[Dovecot] New ManageSieve releases: v0.10.2 for Dovecot 1.1.rc4 and v9.3 for Dovecot 1.0.13
by Stephan Bosch 20 May '08

20 May '08

Hello Dovecot users, Recently, I was pointed towards a problem in the managesieve SASL implementation. As it turns out there was a bug in handling mechanisms that expect more than a single client response. That is why the PLAIN mechanism works and the (obsolete) LOGIN mechanism fails (along with probably many others). This problem was present in both v9.2 and v0.10.1 for Dovecot 1.0 and 1.1 respectively. This issue is fixed in the new releases: Change Log v9.3/v0.10.2 ------------------------ * Fixed bug that caused SASL mechanisms that require more than a single client response to fail. Reported by Steffen Kaiser and occured when he tried using the (obsolete) LOGIN mechanism. * Updated installation and configuration documentation to match the information provided in the wiki Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is finally available on the Dovecot wiki at: http://wiki.dovecot.org/ManageSieve New releases: 1.0: (patch) http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.13-MANAGESIEVE-v9.3.diff.gz http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.13-MANAGESIEVE-v9.3.diff.gz… 1.1: (package + patch) http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.2.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.2.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc4-managesieve-0.10.2.diff… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc4-managesieve-0.10.2.diff… (my public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net) Have fun testing the Dovecot ManageSieve service.

[Dovecot] Looking for suggestions: How to strip attachments from mails
by Patrick Nagel 20 May '08

20 May '08

Hi, I know this is not 100% on-topic, but I'll try anyway... I'm looking for a way to strip attachments from incoming mails on the server. The attachments should be stored on a file server (where users have access via SAMBA) and only a link to the file (UNC path) should remain in the mail body. This is to prevent the mail storage from filling up with a large amount of big mails where at the same time the 'payload' (attached file) is not conveniently accessible by the users. The current setup is postfix / dovecot deliver / dovecot (with sieve plugin). I'm considering piping the mails through something like mimeStrip.pl (http://freshmeat.net/projects/mimestrip.pl/) but therefore I'd probably need to bring procmail/maildrop into the game, right? Or are there other (better) ways to accomplish this?

[Dovecot] messages downloading repeatedly to mozilla/seamonkey pop3 client
by Ben Julian 20 May '08

20 May '08

Hello Dovecot List, I am a bit of a sysadmin novice and this is my first time emailing, so please let me know if I have left some critical information out. I am supporting a small office network supported primarily by linux servers. All of my users are using dovecot as a pop3 daemon on a centOS 5 box, no IMAP users. Seven users are running outlook 2003 on windows XP, two users are running thunderbird on ubuntu, two are running evolution on ubuntu, and one is running mozilla seamonkey on XP. Emails to the mozilla/seamonkey user are downloading multiple times, but not to any of the other users. A typical maillog report following this user's mail client pop3 login: Mar 3 10:37:00 servername dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=::ffff:192.168.99.13, lip=::ffff:192.168.99.4 Mar 3 10:37:00 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84873 > 84872, seq=2, idx_msgs=3) Mar 3 10:37:01 servername dovecot: POP3(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (84877 > 84872, seq=2, idx_msgs=4) Mar 3 10:37:01 servername dovecot: POP3(user): Disconnected: Logged out top=0/0, retr=1/3364, del=1/1, size=3347 Things I've tried: *adding the following lines to dovecot.conf: protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } *deleting the user's homedir mail directory (including all dovecot index files) *restarting dovecot *changing mail clients: tried outlook express, netscape 4.8, thunderbird on user's PC *restarting the server All changes resulted in only a brief (1-2hr) cessation of the problem. I've subscribed for a month or so now and searched the archives, but if I missed a solution to this in there, I apologize. Thanks, Ben Julian

[Dovecot] Fixed a Duplicate?
by Nigel Allen 19 May '08

19 May '08

Greetings We have recently switched from mbox to Maildir so that we can implement symlinks for a large email account that is shared (partially) between some 20 or so users. The setup is dovecot-1.0.3-6.fc6, procmail-3.22-17.1, sendmail-8.13.8-2. Procmail has a single recipe in /etc/procmailrc that simply says "DEFAULT=$HOME/Maildir/". The problem is that I am seeing a lot of blank emails being created. For exaample, every time I open a folder from this shared account, I get either one or two emails being created on the spot. The are /always/ created with the current date and time stamp (i.e. now) and at the same time a tail -f of maillog shows something like this: > May 19 09:10:05 sydsrv56 dovecot: IMAP(plans): Fixed a duplicate: > dovecot-shared:2, -> 1211152205.P10039Q1.sydsrv56 The only thing that appears to change is the last modified date and time of the two files, dovecot.index.log and dovecot.index.cache. Should I be maintaining separate index files or lock files for each user in this shared account? Currently the Maildir is shared and has the g+s bit set. Any ideas where I can start looking would be appreciated. Rgds Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Postfix & Dovecot LDA
by Jochen Schulz 18 May '08

18 May '08

Hi, before I start to write a lengthy email about something that isn't really possible anyway: can I make Postfix use Dovecot's LDA and start it with different user IDs? My scenario: Dovecot authenticates users for Postfix and itself using Postgresql. Mails for two domains should be stored under /srv/<domain>/<user> (which is the location returned by my user_sql query and mail_location). When my clients login (with usernames of the form 'user@domain'), Dovecot creates/opens the correct mailboxes for them, but I can't get LDA to deliver to these mailboxes. Whatever I try, I am always running into some kind of permission problems (either for the mailboxes, or for auth_socket). I want to use a unique UID for every virtual domain, so I guess LDA needs to have permissions for every corresponding mailbox *and* Dovecot's auth_socket_path. Is there a good solution for this which doesn't involve severe security implications? J. -- If all my friends had Playstations I would buy a Nintendo to prove my individuality.

After starting dovecot again after a few minutes the files appear. The processes are running something on 6243 and 6244 (Presumably an exploit / login) I have iptables setup to only allow existing ports in/out so I think thats saved me so far.

[Dovecot] Development news
by Timo Sirainen 17 May '08

17 May '08

First a list of all the new features and their state: 1. http://hg.dovecot.org/dovecot-threadindexes/ THREAD=REFERENCES indexes. Missing NFS flushes, support for mmap_disable=yes, breaks when more than one session modifies at the same time. Not tested much if the replies are really correct at all. Also started THREAD=X-REFERENCES2 but it doesn't work as expected. 2. http://hg.dovecot.org/dovecot-virtualboxes/ Virtual mailboxes. Nothing changed since http://dovecot.org/list/dovecot/2008-March/029546.html 3. http://hg.dovecot.org/dovecot-condstore/ Implemented CONDSTORE, QRESYNC, ESEARCH, SEARCHRES and WITHIN extensions. The only known problem left is making CONDSTORE's STORE UNCHANGEDSINCE operation atomic, but it requires changing transaction log file format. Maybe I'll do it and just make v1.1 and v1.0 be able to read the format and just ignore the modseq in the record. Those code trees don't contain all the latest changes from v1.1 tree. So at some point I'll start merging all of them into one dovecot-1.2 code tree. v1.1 is coming along pretty nicely. I'll make a new RC release in a few days. After that probably one more and then v1.1.0. Tomorrow begins a 5 week lab course at school. Every day and about 8 hours a day. And then we'll also have to write these reports about what we have done and how/why, which takes quite a lot of time as well. After 5 weeks there's one free week and then probably another 2 week lab course if I get selected there. So I doubt I can get much Dovecot work done for the next two months. It's also likely that I won't be answering mails much in this list either.

Changes: - Improved vacation reply checks, log discarded vacation replies (in v1.0.3, these were already in v1.1.0) - Expand ~ to home directory in sieve path - If compiled script has the exact same mtime as the source script, assume the script hasn't changed (changed "<" check to "<="). - Unfold multiline headers before comparing them. - Improved error logging.

[Dovecot] deliver exits with status 89 on some but not all mails of a batch
by Patrick Nagel 16 May '08

16 May '08

Hi, I'm trying to get dovecot's LDA 'deliver' to deliver mails that come in through a postfix daemon on the same box. I'm talking about dovecot version 1.0.rc15 (on CentOS 5 as Linux-VServer guest on a CentOS 5 host). Configuration ------------- # /etc/dovecot.conf ssl_cert_file: /etc/pki/selfmade/server.crt ssl_key_file: /etc/pki/selfmade/server.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login verbose_proctitle: yes mail_extra_groups: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: verbose: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot dovecot-ldap.conf looks like this: uris = ldap://dbserver dn = cn=dovecot,ou=services,dc=company,dc=net dnpass = secret ldap_version = 3 base = ou=people,dc=company,dc=net scope = onelevel user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = LDAP-MD5 postfix has mailbox_transport set to dovecot, and master.cf contains the following: dovecot unix - n n - - pipe flags=DRhu user=fry:fry argv=/usr/libexec/dovecot/lda/deliver -d ${recipient} Problem ------- When a lot of mails come in 'at the same time', for example because an employee mailed all other (local) employees, the following happens: Some mails are being delivered as advertised, but on some mails, deliver exits with status 89 and the message bounces. Here is a (postfix) log that illustrates the problem. I replaced all receivers with 'xy', but they are in fact all different.

[Dovecot] Dovecot dying when deliver is called
by MyGoddess 15 May '08

15 May '08

Hello, I run a debian etch server with the mail services configured like their: http://workaround.org/articles/ispmail-etch/ It worked during month but of the last upgrade it doesn't work anymore when postfix calls deliver. dovecot version is 1.0.rc15. I don't remember which was the previous version. There is no error accessing dovecot in any other way. Here my configuration: # /etc/dovecot/dovecot.conf log_path: /var/log/dovecot_err.log info_log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s imap imaps login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n mail_debug: yes mail_drop_priv_before_exec: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap):You can find a copy of the pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=1004 gid=1005 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail I am not able to get a coredump.

[Dovecot] moving folders bug - rc4
by Anil 15 May '08

15 May '08

I am fairly new to dovecot... I had a user who in outlook tried to move one of the folders into another folder but it crapped out. User tried to move "Djans*" folders into Koi folder. The subscription seems to show the folder move but the actual data is still under ".ClickEats.Clients.Djans" instead of ".ClickEats.Clients.Koi.Djans*. How do I fix this? Thanks. root@the:/apps/mail/clickeats.com/juliam/Maildir# grep -i djan subscriptions ClickEats.Restaurants.Djan's ClickEats.Clients.Koi.Djans.Online Orders ClickEats.Clients.Koi.Djans root@the:/apps/mail/clickeats.com/juliam/Maildir# ls -a |grep -i djan .ClickEats.Clients.Djans .ClickEats.Clients.Djans.Online Orders .ClickEats.Restaurants.Djan's root@the:/apps/mail/clickeats.com/juliam/Maildir#

[Dovecot] Automounted home dirs not working
by Roy McMorran 15 May '08

15 May '08

I'm testing Dovecot as a possible replacement for UW. In my environment the home directories are automounted via NFS from a NetApp. In general this works fine, but Dovecot isn't picking up the automounted directories. Consider the case of Arthur Dent, test user: May 12 10:30:24 testbed dovecot: [ID 107833 mail.info] imap-login: Login: user=<adent>, method=PLAIN, rip=xxx.xxx.xxx.242, lip=xxx.xxx.xxx.242, secured May 12 10:30:24 testbed dovecot: [ID 107833 mail.error] IMAP(adent): mkdir_parents(/home/adent/Mail) failed: No such file or directory May 12 10:30:24 testbed dovecot: [ID 107833 mail.error] IMAP(adent): Mail storage creation failed with mail_location: mbox:/home/adent/Mail:INBOX=/var/mail/adent May 12 10:30:24 testbed dovecot: [ID 961074 mail.error] child 21816 (imap) returned error 89 (if however I make sure that /home/adent is mounted at the server (eg. cd /home/adent) prior to starting the mail client this error does not occur) Why isn't the automount succeeding? This is Dovecot Version 1.0.13. I'm running under Solaris 10. Thanks!

Its not always because someone was lazy about > their time setup. My point exactly. It's amazing how some people are quick to ramble about someone else's administrative incompetence without taking time to read the situation. (One person even suggested hacking the dovecot startup script to run ntpdate -- useless as ntpd already occupies the ports). Fact is, ntpd can take unpredictable delay before the initial time-step. Delay that can't be controlled, and it would be unreasonable to delay starting mail services until it is guaranteed to complete. Then, dovecot dies, and admin (who is not always immediately available) has to start it manually anyway (especially as it is not clear what to do with possibly unsynced timestamps) -- only after the unnecessary downtime. So, the question is: why on earth can't we add a single line of code to dovecot to restart itself after terminating? Kind of reminds me of the "fsck_y_enable=YES" option in rc.conf. Without it, if fsck does not like someting during reboot, the server would just sit there in single-user prompt, waiting for (expensive) console operations. Best wishes Eugene

Isn't this one click at accessing the server the first time!? "Accept this certificate permanently"? But if you figured out, how to add it, let me know! :) Hans

[Dovecot] Allow_nets + MySQL failing when using range notation
by Javier García 15 May '08

15 May '08

Hello all, I am testing my dovecot installation in order to restrict access via POP3 for IPs outside my network. I have read and understood the instructions in the wiki and I have reached a configuration that works ONLY when single IPs are listed in allow_nets but not when ranges in the notation x.x.x.x/y are listed. Some examples should be more explanatory. I am using 1.0.rc15 patched as for last week as distributed in Debian etch. First of all, everything related to this is stored in a MySQL database, here is my password query: password_query = SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.%Ls = 1 ) and u.mail = '%u' This one should validate all mail addresses when the protocol used is marked as 1 in table access_type and when the allow_nets value in this same table contains the IP used for the access request. The, if access_type looks like: ID_access pop3 imap allow_nets 3 0 1 10.34.128.0/23, 10.34.133.0/24, 192.168.0.0/24 users with ID_access=3 fail to login by either pop3 (normal, value is 0) or imap. Here is the corresponding excerpt from dovecot.log: dovecot: 2008-03-31 11:29:04 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.imap = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 192.168.0.0/24 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.128.0/23 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.0/23 dovecot: 2008-03-31 11:26:39 Info: auth-worker(default): passdb(user(a)domain.com,10.34.133.104): allow_nets check failed: IP not in allowed networks but if it looks like ID_access pop3 imap allow_nets 3 0 1 10.34.133.105, 10.34.133.104 then access is allowed by IMAP dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.imap = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.105 dovecot: 2008-03-31 11:34:01 Info: auth-worker(default): auth(user(a)domain.com,10.34.133.104): allow_nets: Matching for network 10.34.133.104 dovecot: 2008-03-31 11:34:01 Info: auth(default): client out: OK 1 user=user(a)domain.com while POP3 still disallowed as expected: dovecot: 2008-03-31 11:34:25 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): query: SELECT u.password as password, t.allow_nets as allow_nets FROM users u, access_type t WHERE u.ID_access_type = t.ID_access and ( t.pop3 = 1 ) and u.mail = 'user(a)domain.com' dovecot: 2008-03-31 11:34:25 Info: auth-worker(default): sql(user(a)domain.com,10.34.133.104): unknown user So, is there a bug related to the IP class notation or am I doing something wrong? I have tried to leave a single class (10.34.133.0/24), to explicitly erase any spaces after the commas, but nothing of these worked. Also, note that using 0.0.0.0/0 behaves as expected, this is, access for any IP is allowed. Thanks in advance, Javier

[Dovecot] Mixed maildir and mbox folder
by Stefan Klatt 15 May '08

15 May '08

Hello, i tried to implement a mixed structure of mbox for spams and spam backscatters and maildir for the rest at dovecot 1.0.13. I used the information at the dovecot wiki: http://wiki.dovecot.org/Namespaces (Multiple Mailbox Locations) But if i try this (complete config is attached with this part) namespace: type: private separator: / prefix: "#md/" location: maildir:/srv/imapd/user/%u/maildir inbox: yes hidden: yes namespace: type: private separator: / location: mbox:/srv/imapd/user/%u/Spam thunderbird can't open a maildir folder:-( The msg is " Mailbox doesn't exist: XXXX" If i use this version: namespace: type: private separator: / location: maildir:/srv/imapd/user/%u/maildir inbox: yes namespace: type: private separator: / prefix: "#mb/" location: mbox:/srv/imapd/user/%u/Spam hidden: yes Thunderbird can open maildir folder but no mbox folder.. " Mailbox doesn't exist: XXXX" :-( Where is my fault? Or is this feature first complete implemented at 1.1? I configured namespaces without hidden like a charme... with hidden i run against a wall :-( Other question... has anybody a script to delete messages older then XY days in a mbox file? Here is my complete config with the first config version: [root@kronos etc]# dovecot -n # 1.0.13: /etc/dovecot.conf ssl_cert_file: /etc/pki/tls/certs/xyz.cert ssl_key_file: /etc/pki/tls/private/xyz.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_process_size: 32 mail_access_groups: email dotlock_use_excl: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins: zlib mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle namespace: type: private separator: / prefix: #md/ location: maildir:/srv/imapd/user/%u/maildir inbox: yes hidden: yes namespace: type: private separator: / location: mbox:/srv/imapd/user/%u/Spam namespace: type: public separator: / prefix: Public/ location: maildir:/srv/imapd/shared/public/maildir:CONTROL=/srv/imapd/user/%u/shared-settings/public/control:INDEX=/srv/imapd/user/%u/shared-settings/public/index namespace: type: public separator: / prefix: Archiv/ location: mbox:/srv/imapd/shared/archiv/maildir:CONTROL=/srv/imapd/user/%u/shared-settings/archiv/control:INDEX=/srv/imapd/user/%u/shared-settings/archiv/index auth default: passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: static args: uid=600 gid=600 Stefan

[Dovecot] homedir override problem, MS AD + WINBIND + PAM + SIEVE
by Milan Koudelka - Internet Mall 15 May '08

15 May '08

Hello, i installed my Dovecot with authetification in MS AD throught WINBIND and PAM. Works fine. So I have virtual users with UID, GID from MS AD. I set maildir path as mail_location = maildir:/var/spool/mail/%n/ Then i want to make some vacation system. I install sieve and use dovecot LDA. In postfix main.cf I have mailbox_command = /usr/libexec/dovecot/deliver Setup of lda in dovecot.conf protocol lda { postmaster_address = postmaster(a)mail-server.cz log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log mail_plugins = cmusieve } Sieve user-scripts doesn't work without this: plugin { sieve = /var/spool/mail/%n/.dovecot.sieve } With this settings, LDA and sieve works OK. I can use user-scrips to forward mail by subject or something like this. Vacation rules works too. But it isn't create .dovecot.lda-dupes in user home directory that contains e-mail addresses that was replied. So vacation is sent always. I have this error in dovecot-deliver.log deliver(mkoudelka): May 14 12:24:19 Error: open(/home/MALL/mkoudelka/.temp.cz-dc1-s-018.mall.cz.11302.7e2cc05a1e1df1a7) failed: No such file or directory I tried to override home directory by set this: userdb passwd { args = home=/var/spool/mail/%n } But there isnt't any change. Can you please, help how to set correct home for sieve ? MALL is domain of user mkoudelka. Thank you -- Milan Koudelka Linux & Network Administrator Internet Mall, a.s.

[Dovecot] Disconnected: BUG internal error
by Ainsley Pereira 15 May '08

15 May '08

Hello, I'm seeing some messages from dovecot in my logs such as: May 8 11:43:41 snowdrift dovecot: IMAP(username): Disconnected: BUG: Unknown internal error I did some searching, and discovered a similar report last month, to which there was a request for more information that didn't seem to get followed up, so I have collected this information too. Dovecot version: 1.0.10 (from Ubuntu hardy package, which includes some patches; details of the patches can be found here: http://svn.debian.org/wsvn/collab-maint/deb-maint/dovecot/trunk/debian/patc… ) OS: Ubuntu 8.04 (Hardy) CPU: x86 Filesystem: ext3 IMAP client: Thunderbird. What was happening with it is not too clear, unfortunately it only seems to occur for one user, and that's not me. Reproducability: Seems to occur fairly frequently, but unable to provide steps. dovecot -n output: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s ssl_cert_file: /etc/ssl/certs/snowdrift-cert.pem ssl_key_file: /etc/ssl/private/snowdrift-key.pem ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd Raw log output: 29 OK Fetch completed. * 632 FETCH (UID 14265 RFC822.SIZE 4373) * BYE BUG: Unknown internal error Immediately before that was a set of headers from an email, so I guess that's what the "29" line's talking about, and it's just the last two that are relevant. Please let me know if there's anything further I can provide to help track this down. Thanks, Ainsley

[Dovecot] unix style mbox and vmain maildir on the same server
by Glen Lee Edwards 15 May '08

15 May '08

Hi, I'm new to dovecott. Using version 1.0.rc15. I have a mail server that has both the old style unix mbox in /var/mail/%u, and virtual mail maildir in /var/vmail/%d/%n. Debian Linux Etch stable. I'm trying to get dovecot to deliver to /var/mail/%u using mbox format, and to deliver to /var/vmail/%d/%n using maildir format. I can't get it do work. I can get it to access both directories, but not use the two formats. This is what I tried last: namespace private { separator = / inbox = yes hidden = yes prefix = location = mbox:~/mail:INBOX=/var/mail/%u } namespace private { separator = / inbox = no hidden = yes prefix = mail/ location = maildir:/var/vmail/%d/%n } I have since commented out the above two namespaces and set mail_location to mail_location = maildir:/var/vmail/%d/%n. $ dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login passdb: driver: pam args: dovecot passdb: driver: passwd args: blocking=yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=2000 gid=2000 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail Glen

[Dovecot] Problem with virtual mail user login users uid not permitted
by Neil Muller 14 May '08

14 May '08

Hello, I am trying to run exim 4.68 and dovecot 1.0.13 on Solaris 10 x86 5/08 using dovecot lda and sieve with virtual users and domains, tls and ssl. At the moment certificates are from my internal CA Exim and Dovecot, dovecot lda and dovecot sieve were downloaded and installed from Blastwave.

[Dovecot] Time moved backwards
by Eugene 13 May '08

13 May '08

Hello, I would like to suggest a change in handling of 'Time moved backwards' problem. Right now dovecot just dies. So, the scenario: 1) Colocation server is shut down for some reason. The internal time drifts. 2) Server is started again. 3) Dovecot starts successfully. 4) In about a minute, NTP daemon feels confident about adjusting the system time. 5) Dovecot sees the changed time and dies. 6) Admin has to notice that, login and restart Dovecot manually. I suggest that Dovecot simply terminate the current connections (causing the client to reconnect) or -- if the time change is really that much of a problem -- to restart itself automatically. Maybe a config option could be introduced. Best wishes Eugene

Hello, I just found this message in our dovecot logfiles: "Disconnected: BUG: Unknown internal error" Should I worry about this ? There are no complaints yet (although it is not limited to one user). It seems to occur with different clients (Apple/MacOS mail, Windows/Thunderbird, Pine). We're running dovecot 1.0.10 on Solaris 10 with mboxes (NFS) and local index storage. There are no such messages before the upgrade (from version 1.0.5). Regards.

Hi All, I'm trying out the imapsync migration tool, migrating user mails from cyrus IMAP to Dovecot IMAP. In order to avoid knowing about each of the users password, I use the cyrus admin user in the cyrus end. Is there such a thing as the dovecot admin user, or is that simply the root user?

[Dovecot] imap memory footprint rather large
by martin f krafft 12 May '08

12 May '08

Dear list, I am experimenting with a new mail handling setup and it involves a single IMAP folder with just under 70'000 messages. When OfflineIMAP connects to the server, the imap process starts to eat up a lot of memory: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 15607 madduck 35 19 283m 244m 239m D 16.9 49.3 0:09.96 imap On the contrary, when "online" client, such as Thunderbird connect, memory usage is around 10m, which is entirely acceptable. The way offlineimap reads may is by FETCHing metadata, then APPENDing new local mail, SEARCHing for the UIDs of each uploaded mail, and finally FETCHing new remote mail. Memory use seems to be O(n) in the size of the folder. On the folder with 70k messages, dovecot seems to allocate 280m of memory, which it then fills to about 70% during the metadata FETCH, and then keeps growing while APPEND/SEARCHing the new local messages. The 70k mailbox is just short of 600Mb in size on disk. Dovecot uses 280Mb to serve it. Is it possible that dovecot is reading too much into memory, or over-optimising? Can I somehow tweak this to lower the memory footprint?

[Dovecot] Another numptie question - making maildirs for shared mailboxes.
by Stroller 12 May '08

12 May '08

Hi there, Sorry to have so much trouble with my Dovecot setup & to ask so many questions, but I'm having some problems with shared folders. I've read the thread at <http://dovecot.org/pipermail/dovecot/2005-January/006079.html> and added the following lines to /etc/dovecot.conf: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = General/ location = maildir:/tmp/dovecot-test/ inbox = no hidden = no } So I create a directory /tmp/dovecot-test/ and an empty file /tmp/dovecot-test/dovecot-shared with liberal (777 & 666 respectively) permissions and then try to subscribe to the "General" folder in Outlook - I get a "failed to subscribe to the folder. The server responded `the mailbox doesn't exist: General`" error message, but cur, new & tmp are created in /tmp/dovecot-test. These subfolders are owned by the user that attempted to subscribe & have 700 permissions; chmod'ing them 777 makes no difference. Since "default_mail_env = maildir:%h/.maildir" in dovecot.conf I make a directory /tmp/dovecot-test/.maildir also containing cur, new, tmp & dovecot-shared. When I select "IMAP folders" in Outlook I am still unable to subscribe to "General" but am now able to subscribe to "General/maildir". The subscribed folder is shown in Outlook underneath the users' Inbox as a sub-folder of general, screenshot at <http://linux.stroller.uk.eu.org/DovecotSharedFolders.png> - see how I can't subscribe to "General" alone, but it is "brought in" by subscribing to "General/maildir"? If I try to copy a test message into General then, after a delay of a minute or so, I get "Can't move the items - this IMAP command could not be sent to the server before the connect was terminated"; if I try to copy the test message into General/maildir then I immediately get "Can't copy the items. The server responded: `Internal error occurred. Refer to server log for more information [2005-12-20 12:05:40]". I've tried tinkering with other directory structures under /tmp/dovecot-test/ with no success - can anyone suggest what I'm doing wrong, please? It's quite important to me that the "General" folder is a fairly high-level one - only one additional folder icon should show up for the users' shared mail. At one point I managed to create a folder General/General, but that's undesirable - the users wouldn't understand the concept of having a folder showing in Outlook that they can't write to, or which is only used as a container for another folder. (In any case, I believe I was still unable to write to it). I was about to say, "I know I could resolve this with the use of a symlink-type shared folder, but that's undesirable because I'd have to manually add the symlink for each user that's added to the system", but writing this it occurs to me that I could resolve that by adding the symlink to the the etc/skel/. Nevertheless, I see the namespaces approach as more elegant, as it allows for different user groups having different shared folders. I'd appreciate any advice - I suspect I'm just getting the directory hierarchies wrong, or the syntax of dovecot.conf wrong AGAIN! If anyone with a working shared folders setup could provide a copy of the appropriate section of dovecot.conf & a listing of the appropriate directories then I'd be EXTREMELY grateful. Stroller.

[Dovecot] IMAP, Shared folders, symlinks and permissions
by Nigel Allen 12 May '08

12 May '08

Greetings Using FC7, dovecot-1.0.3-6.fc6 and maildir I have a recurring problem with permissions. We have a (real) account on the system called "custs". Within the email account for custs there exists some 300 folders, one for each customer. This worked okay originally with mbox. Everyone had access to their own email folders and they all had access to the "custs" account. They only problem is that to find one folder (customers)'s emails, you had to scroll through 300+ folders. For the people who need access to all of the custs' folders, there was no problem (apart from a real estate one of scrolling which sometimes caused people to drag and drop into the wrong folders). The problem is that around 16 staff need only access to a subset of customers (i.e. the ones they manage - around 20 each) while the rest of the staff need access to the lot. What we did was to convert everything to Maildir so that we could use symlinks. So far so good. We created symlinks from /home/custs/Maildir/customer1 to /home/manager1/Maildir/customer1 and from /home/custs/Maildir/customer2 to /home/manager2/Maildir/customer2. Again, so far, so good. Manager 1 gets access to Customer 1 and Manager 2 gets access to Customer 2. The problem comes when someone who ONLY has access to the "custs" account drops an email into Customer 1. The file dovecot-uidlist gets created and suddenly Manager 1 cannot see the folder. We changed (in desperation) the group owner of custs/Maildir to "common" (which everyone is a member of) and did a chmod g+s from the custs/Maildir down. e even set the permissions of the custs/Maildir/* to 777 to watch what was happening. It appears that the permissions on the file dovecot-uidlist is set to 600 every time someone drops an email into the folder. Then when someone else tries to access the folder they get a "permission denied" error on dovecot-uidlist. Can anyone explain to me how to: Change the way dovecot creates the dovecot-uid files so that the permissions are set to 660 or 666 or Set this up better so that we can share all these folders. Any suggestions, questions, comments will be (very) gratefully accepted. Rgds Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] BUG: Bad grep when building dovecot?
by Andrew Lentvorski 12 May '08

12 May '08

Is dovecot *really* that picky about grep, or did it just happen to pick up an autoconf that's being overly pedantic? I saw this message a couple of times when googling, but no particularly good solution presents itself. I'll probably give it a new GNU grep just to get it to shut up, but I'm a bit surprised. I tried to compile dovecot in an OpenSolaris 2008.5 system in a zone (which is quite a bit more minimal than base OpenSolaris). bash-3.2# uname -a SunOS postfix-s0 5.11 snv_86 i86pc i386 i86pc bash-3.2# ./configure --help `configure' configures dovecot 1.0.12 to adapt to many kinds of systems. bash-3.2# which grep /usr/bin/grep bash-3.2# grep -v Usage: grep -hblcnsviw pattern file . . . bash-3.2# which egrep /usr/bin/egrep Error in configure: checking for cc option to accept ISO C89...

[Dovecot] MBOX to Maildir preserving the UIDL (outlook-tested, no redownloading)
by Horn Wijaya 09 May '08

09 May '08

TESTED AND RUNNING, MIGRATING from MBOX to MAILDIR, PRESERVE UID and OUTLOOK sees the email as downloaded. I hope this helps a lot of people out there. Feel free to post this somewhere else too. By: Horn Wijaya (hwijaya(a)nodens.biz) 8th May 2008 I have been searching for weeks for a foolproof method to migrate all my users mbox to maildir/dovecot without having the pain of downloading all emails again, especially for heavy users. It would cause frustration to thousands of my users. So.... eventually I found out why Outlook will keep downloading the emails despite all the configuration done in the dovecot.conf. Apparently the UID is generated realtime. When it first generated, it took the time the process runs. Before I migrate, here's the email sample which I have downloaded to my outlook (and keep email on server), and then I use telnet to pop to get the uidl list. +OK POP3 localhost.localdomain v2003.83rh server ready user ***** +OK User name accepted, password please pass ***** +OK Mailbox open, 444 messages uidl +OK Unique-ID listing follows 1 47b1303d00004c2d 2 47b1303d00004c2e 3 47b1303d00004c2f ... 47b1303d = 1202794557 = 12 Feb 2008 13:35:57 the date and time the mbox was created 00004c2d = 19501 the IMAP counter so far.... sequently added as you could see with email #2 and email #3 Then I switch my POP server to dovecot, and migrate my MBOX to Maildir, and I do a telnet to get the UIDL +OK Dovecot ready. user ***** +OK pass ***** +OK Logged in. uidl +OK 1 4822815000000001 2 4822815000000002 3 4822815000000003 ... 48228150 = 1210220880 = NOW 00000001 = counter starts at 1 No wonder outlook sees the emails are NOT-DOWNLOADED-YET status. Then I ponder for another few days and the key is in the dovecot-uidlist...... How to fill it with the correct info.... and there's a way. Which I hope useful for converter developer, and could be implemented in the next version of the converter. Here's the step I do to reach my objective which is to get UID 47b1303d00004c2d in the first email: 1. mb2md-3.20.pl -s /var/mail/hwijaya -d home/hwijaya/Maildir/ that's converting 444 emails from mbox to 444 files in the Maildir/cur folder 2. cd /home/hwijaya/Maildir/cur 3. grep IMAPbase * and I get 1210219860.000000.mbox:2,S:X-IMAPbase: 1202794557 19944 The last 2 strings are the KEY to the ORIGINAL UID 4. So in order to prepare the environment to fool it, some calculations are needed: How do we get 19501 as the first counter? as expected in the first POP TEST above: 19944 - 444 emails + 1 = 19501 5. cd /home/hwijaya/Maildir 6. echo '3 V1202794557 N19501' > dovecot-uidlist 7. DONE....... pop it via outlook and nothing will be downloaded, after pop or imap is processed, the dovecot-uidlist is auto-filled, index auto generated.

[Dovecot] [Q] IMAP update message header?
by Roderick A. Anderson 08 May '08

08 May '08

More about IMAP, less about Dovecot. This is more an IMAP question than specifically about Dovecot. Sorry to ask here but I've been researching, reading and lurking with no answer so far. What I'm doing is running reports as a user from a remote system to provide a list of messages (Sender/From, Subject, Date, size) in a specific folder(?). In one case it isn't even a Dovecot based server so I only have access as a client. (Though I use Dovecot on several other systems and will need this capability for them.) When a message in the folder has been reported I'd like to add a X-Header-??? indicating that the message has been reported so the next time through it isn't reported again. (After the message is X days old it is deleted.) These reports are run using Perl and I've tried most every CPAN module available but haven't figured out how to change/add a header then save the message back. So far I haven't been able to determine if this is even possible by reading the RFCs. Is there a method as a client from a remote system to make changes to a message then save it back? What is the IMAP verb, command, etc. to do this? Or if there are Perl programmers on the list a brief description (or code) for doing this? TIA (and sorry for the off topic posting), Rod --

This will allow you to test things and see if it works better. The changes will revert to the system pre-defines when you re-boot or restart. IIRC, there is a master setting (unchangeable without recompiling OS X) that will not allow you to go over 65536, but I may be mistaken about that. For a permanent change, add the following lines to the /etc/sysctl.conf file: or the /etc/sysctl-macosxserver.conf file for Mac OS X Server You may have to create the file, especially if you are the only user. (Make sure that only root has access to this file!!!!!!) kern.maxfiles=65536 # System-wide limit kern.maxfilesperproc=32768 # Per-process limit This Is ONLY For OS X 10.3 or later. For earlier versions you need to use /etc/rc which was so long ago that I do not recall all of the commands (sorry). HTH, Jerry

[Dovecot] How do I increase the fd limit on OS X?
by Rob Frohne 08 May '08

08 May '08

Hi All, I just upgraded to the new 1.1rc5 from 1.0 that I had been using and it advised me to increase the file descriptor limit. I'm not sure how to do this. There is a command built into tcsh that allows me to do this called limit, but sudo limit 4224 doesn't work, and usually dovecot is started from the rc.local file if I recall right, and I'm not sure how to set this up from there. Any advice. Thanks, Rob -- Rob Frohne <rob.frohne(a)wallawalla.edu> Walla Walla University

Not true! simple way: Just change the default config TB create your account from with the settings you need. You can find the file under your program dir i.e. C:\Programme\Mozilla Thunderbird\defaults\pref Compare the defaults to your working set of setting and change them accordingly. You can activate TLS or CRAM-MD5 and so an.

[Dovecot] thunderbird sane config (OT)
by rosenfield.albert＠gmail.com 08 May '08

08 May '08

Does anyone have any experience putting together a sane config for Thunderbird in an automated fashion? Automated meaning "simple to distribute to users". -- (Background: I'm currently experiencing that Thunderbird does not work against Postfix/Dovecot because the wizard interface for setting up an account does not accept TLS-only servers. Users just sit there with a broken Thunderbird, not knowing what to do :-/.) (PS: Also, giving everybody a GMail-like threaded interface per default would be cool.) (PPS: If anything good comes up, I plan to put this in fx the Dovecot wiki.)

[Dovecot] Clarification wanted on mail_access_groups vs. mail_privileged_group
by Mark Sapiro 07 May '08

07 May '08

I have just upgraded to dovecot 1.0.13. All the documentation I can find in the example .conf file and the NEWS and ChangeLog files seems to say that the mail_privileged_group = mail setting is all I should need to make dovecot use group mail to create dotlock files. My understanding from what I read is that mail_privileged_group is used to set the group used while creating dotlock files in (in my case) /var/spool/mail, and mail_access_groups is used to set the group used to actually access the mailbox. In my case, /var/spool/mail is group 'mail and group writable/searchable drwxrwxr-x 2 root mail 4096 May 7 08:35 /var/spool/mail and the individual mailboxes are owned by the respective users. So it seems that I would need "mail_privileged_group = mail" do be able to create dotlock files in /var/spool/mail, and that I would not need any mail_access_groups as the users can access their own mailboxes. But this doesn't work. With "mail_privileged_group = mail" and mail_access_groups unset, I get May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Yet with "mail_access_groups = mail" and mail_privileged_group unset, it works with no problem. Is my understanding wrong? Is the documentation wrong? Is the implementation wrong? Or is there just something wierd in my case (possibly pop3_lock_session = yes)? # dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf protocols: pop3 pop3s ssl_cert_file: /etc/postfix/grizz-cert.pem ssl_key_file: /etc/postfix/grizz-key.pem login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_access_groups: mail mail_location: /var/spool/mail/%u mbox_write_locks: fcntl dotlock mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] dovecot pop3 proxy with AUTH PLAIN
by Luis Barrueco 07 May '08

07 May '08

Hi, I tried as hard as I could, but I couldn't get this working. So here I come begging for help :) I need to configure dovecot to proxy some users' incoming pop3 connections to another server running the Zimbra Collaboration Suite, trying to log into zimbra via a master password. The problem I found is that zimbra only allows me to log in as a master user with the "AUTH PLAIN" mechanism, but it seems that dovecot uses the "USER.... PASS" authentication when proxying. Am I missing something? Has anyone ever tried to do the proxy+master password to zimbra? I'll post my configurations down here.

[Dovecot] Manual thread breaking from Thunderbird
by Christian Jaeger 07 May '08

07 May '08

Hello I'm looking for a way to manually break threads apart when independent threads are mixed up, mostly by users which aren't aware that they should not be replying to existing threads when starting a new one. Since Thunderbird afaik does the threading itself, it would require a solution that actually changes the In-Reply-To header (and maybe also that other (non-standard?) header which is being sent by the M$ clients). For me modifying the actual emails on disk would be fine, i.e. renaming the In-Reply-To header to Old-In-Reply-To and such. (I'd actually *prefer* a solution that modifies the server side store, as opposed to one which keeps that info on the client side only like mutt seems to be doing.) Is there a way to do this already? Seems like a task for a dovecot plugin--or for the xexec plugin and an external perl script or some such? For triggering the renaming, a hacky solution could be to misuse labels (e.g. marking a message starred and "Later" and "Important" at the same time would trigger the modification and remove the labels). When implementing such a thing: maybe also offer a way to modify subjects (for those cases where people are using short meaningless and recurring subjects--to both help breaking up the ensuing threading as well as giving them a useful replacement), maybe as an IMAP extension or such (to be used by Thunderbird plugins (?), or by web apps). (I can code in C and Perl, but don't generally have much time.) Christian.

[Dovecot] Question about Maildir automatic cleanup.
by José Ildefonso Camargo Tolosa 07 May '08

07 May '08

Hi! I want to automatically delete old messages from one user's Maildir, and I was thinking on running something like this: find /home/user/Maildir/cur/ /home/user/Maildir/new/ -daystart -mtime +15 -delete but I'm not sure if by deleting messages "manually" I will break the dovecot.index* files. What do you think? Thanks! Ildefonso. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

[Dovecot] 1.07 to 1.0.13 mail_extra_groups
by Mark Sapiro 07 May '08

07 May '08

I have just upgraded from 1.0.7 to 1.0.13. I read the comments in the example .conf file and it seemed what I needed to enable dotlock access to mailboxes in /var/spool/mail (writable by 'mail' group) was "mail_privileged_group = mail" so I removed the "mail_extra_groups = mail" that I had in 1.0.7 and added "mail_privileged_group = mail", but I got errors like the following: May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX: Internal error occurred. Refer to server log for more information.

This seems to have the effect of setting both "mail_privileged_group = mail" and "mail_access_groups = mail" as well as issuing "Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead" when dovecot is started. So my question is what do I need. I thought it would be just "mail_privileged_group = mail", but that doesn't work. Do I need both "mail_privileged_group = mail" and "mail_access_groups = mail" or just "mail_access_groups = mail". Also, are the comments describing these in the example .conf file correct, or are they reversed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] deliver custom maildir creation
by Steve Roemen 06 May '08

06 May '08

/ I'm testing a new setup of postfix using deliver to put the messages into the user's maildir, and am curious if there is a way to make deliver create custom maildirs when it delivers to a valid user without a maildir? Right now it only creates the inbox, I'd like it to create the .sent/ .Trash/ and .SPAM dirs. Is this possible? Thanks -------------------------------------- / /Steve Roemen// /

If the user received new mail on the new system, say, around 200kb, and then he/she logs in, messages from the old system are copied. If he had 100Mb of mails (old system), and quota is 20Mb, only the 200kb are shown. Dovecot was not restarted. The problem was what you pointed out, maildirsize had to be deleted, then everything seems to be ok - getquotaroot indicates 100Mb + 200kb. > How badly wrong is the quota?

User has +100Mb, quota 20Mb, quota indicates 0 or just the new mail count (messages received on the new system).

[Dovecot] imap fs quota (rpc) won't work?
by Adam McDougall 06 May '08

06 May '08

In the past I dabbled with the imap quota plugin with the fs backend because I wanted to report usage to my users (not limit them). At the time, the quota plugin would make dovecot crash when trying to write to a folder (I can bring up this report if needed). However, in a later beta of dovecot 1.1 I tried quota again but I cannot get it to report any results. I've been wanting to use fs:noenforcing but also tried just quota = fs to simplify. When I right click a folder stored in my homedir, thunderbird tells me 'the server does not support quotas' in the folder properties. What else can I do? Thanks!

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by David Jonas 06 May '08

06 May '08

Upon upgrading from 1.0.2 to 1.1rc4 I see this error for many of our users: Getting size of message UID=1 failed Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged Logging in with IMAP I would see a bunch of messages with no subject or time and blank bodies (usine horde/imp). Removing dovecot.index.log, dovecot.index.log.2, or dovecot-uidlist fixes the problem for the account (I chose dovecot.index.log). I imagine that forces a rebuild of the indexes. Removing other files in the directory didn't seem to make a difference, including dovecot.index or some arbitrary non-dovecot file. Is there a more conventional way around this problem?

[Dovecot] A previously unreported lsub/list discrepancy in 1.1rc5 and earlier
by Adam McDougall 06 May '08

06 May '08

Not sure about 1.0, I don't run it anymore :) But a few users discovered for a small issue that only affects a very small portion of my userbase where instructional correction will suffice. I guess I am reporting it in the interest of getting it out there, and I can live with it if not fixed but it might be an issue for some people. I'm running through my list of issues. Basically, if a user has a valid namespace prefix set such as mail/ (used to be required on old mail server but discouraged on new mail client setups with dovecot), lsub/list do not show public namespaces that the user has permission to via acl. If the user removes the namespace prefix, they can 'see' the public folders and subscribe. Additionally if the user subscribes to a public folder then puts mail/ back in the prefix, the folders are no longer listed. Not sure if public folders should be affected by the requested prefix in this manner, since they are not in the user's account.

[Dovecot] Replication milestone 1
by Timo Sirainen 06 May '08

06 May '08

5 milestones planned currently. I'll start with the always-on multi-master replication, because that's the most difficult one to get working correctly and efficiently. So if during its implementation I find some design problems, less code needs to be fixed. Milestone 0 will hopefully be done within a month. This includes reading and replying to the rest of the mails on this list and getting a v1.1.0 release out. :) There will most likely also be a v1.2.0 release this summer that has some new features on top of v1.1. Several companies have asked for replication within the past year. At least two are willing to contribute some money into its development this summer, but having more wouldn't hurt of course. :) Paying also guarantees (within reasonable limits) that I'll listen to what kind of a installation you're planning and make sure that the replication will work in that kind of a setup. So, below's the milestone 1 fully described with a couple of FIXMEs left. The rest of the milestones are described only briefly. 0. Prerequisites: - Change v1.2 CONDSTORE implementation to allocate modseqs differently. Currently log file sequence + offset determines the modseq. This can't work in a cluster since their log files are different. Instead add a new "UIDs [..] have modseq X" transaction log record that gets updated when needed. UID list can be 0 to update higest-modseq. To avoid adding modseq for all changes, we can be optimistic and assume that usually multiple servers aren't doing changes at the same time. So the next transaction after modseq=5 record will have modseq=6 and the following one modseq=7, etc. - Update v2.0 framework to include v1.2 changes and make it work. Base the replication code on top of v2.0. - Shared mailboxes making all users' all mailboxes available for read/write within the same (replication) process. 1. Incremental replication for existing mailboxes. IMAP, POP3 and deliver use a replication plugin, which connect to a replication process via UNIX socket (or TCP optionally for chroots). The plugin sends the SAVE, EXPUNGE and STORE changes to the replication process, which forwards them to other servers. The other servers receive the commands and store them to local filesystem. The sending and the receiving sides have quite distinct jobs, so they should probably be implemented as separate processes. They could still use the same TCP socket though, replication sending process writes to the socket and replication receiving process reads the socket. The processes still need to share some state though. Most importantly keeping track of the mailbox master servers. This is probably the most cleanly implemented by having a separate master tracking process which the sending/receiving processes talk to via UNIX socket. The rest of the data sharing is about forwarding command replies (SAVE, STORE with CONDSTORE flag) to replication sender, so it can pass them on to the originating mail process. This can be done easily using an extra pipe/socket between the processes. Examples use: - C1 = Client 1 - C2 = Client 2 - S = Replication sending process - R = Remote replication receiving process - Small letter before commands = IMAP-like command tag - * before commands = tag for a command that doesn't expect a reply 1.1. Master tracking process Master tracking process is connected to sending and receiving replication processes. LOCK: (mail process -> replication sender -> master tracker) - User name - Mailbox name Reply: - success LOCK is sent by replication plugin from mail processes when it wants to assign UIDs for new messages. Replication sender proxies this command to master tracker. If server is already the master, the command returns success immediately. Otherwise tracker looks up from its cache who the current master is and requests it using the REQUEST command. Once GIVE command is received, reply success to the mail process. FIXME: handle timeouts (and master disconnections) somehow? UNLOCK: (mail process -> replication sender -> master tracker) - User name - Mailbox name No reply. UNLOCK is sent by mail processes after they've finished assigning UIDs and sending replication SAVEs. If this was the last lock, pending TAKE requests for this mailbox are handled. GIVE: (replication receiver -> master tracker) - User name - Mailbox name No reply. Notification that this server is now the master for the specified mailbox. If there are any pending LOCK requests for this mailbox, they're replied to in here. TAKE ([mail process ->] replication receiver -> master tracker): - User name - Mailbox name - Server ID No reply. Request for giving master state for the specified server. When this mailbox contains no locks, the TAKE command is forwarded to replication sending process which passes it to the requesting server. While waiting for existing locks to be releases, handling new LOCK commands for the mailbox must be delayed to avoid lock starvation. When forwarding TAKE command, the destination server ID is cached as being the mailbox's current master. If we're not the current master for this mailbox, forward the request using REQUEST command. This also happens if there are multiple pending TAKE requests. The first one gets to become the master and the rest of them are handled as REQUEST commands. REQUEST (master tracker -> replication sender): - User name - Mailbox name - Server ID of the current assumed master - Server ID who wants to be the new master (e.g. ourself) Request master status to be moved to the specified server. If server ID isn't ours, cache it as being the mailbox's current master. If we don't have any idea who the master might be currently, use the root server ID. ROOT-SET (replication receiver -> master tracker): - Server ID This command causes all cached master states to be dropped. Any new LOCK requests are delayed. Once all mailboxes are unlocked, drop being a master from all mailboxes and send ROOT-CLEAR command to replication sender, which passes on the information that we've cleared the master states. The given server ID is set to be the new root. ROOT-CLEAR (replication receiver -> master tracker): - Server ID Given server ID has notified that it has cleared its master states. If we're not the current root, this command is forwarded to it. If we're the root and this was the last pending ROOT-CLEAR, start handling the pending REQUEST and LOCK commands. FIXME: How is initial root selection done? How is it decided who's the new one when previous one dies? 1.2. Replication sending 1.2.1. Saving (For now we ignore the possibility of saving as non-master.) When a mail process wants to give UIDs for newly saved messages, it first requests for master lock for the mailbox from the master tracker process. Once UIDs have been assigned for the new messages, the messages are sent to replication sender using SAVE commands. After the last one is sent, the master lock is dropped. Note that this lock duration should be as small as possible, so in Dovecot's code this means doing both locking and unlocking in mailbox_transaction_commit(). If multiple processes are sending SAVEs at the same time, the replication sender may receive the UIDs in wrong order. It must reorder them before forwarding the SAVEs to other servers. Since all master LOCK/UNLOCK commands pass through the replication sender, it can figure out when it has seen all the SAVEs based on them. For example: C1-C3 -> S: a LOCK [1] S -> C1-C3: a OK [Client 1 sends the first mail] C1 -> S: b SAVE uid=5 .. [SAVE uid=5 depends on dropping [1] locks (currently clients 1,2,3)] C1 -> S: * UNLOCK [1] (left 2) [Client 1 starts sending more mails in a separate transaction, lock counter is incremented because of the previous SAVE] C1 -> S: d LOCK [2] (remember lock[2].prev_uid=5) S -> C1: d OK [Client 2 sends its mail] C2 -> S: b SAVE uid=9 .. [SAVE uid=9 depends on dropping [1-2] locks (currently clients 1,2,3)] C2 -> S: * UNLOCK [1] (left 1) [Client 3 sends its mail] C3 -> S: b SAVE uid=3 .. [SAVE uid=3 depends on dropping [1] lock (currently client 3). It doesn't depend on [2] lock, because uid < lock[2].prev_uid (3 < 5)] C3 -> S: * UNLOCK [1] (left 0) [SAVEs depending on [1] locks are ordered and forwarded.] S -> R: x SAVE uid=3 .. S -> R: y SAVE uid=5 .. [Client 1 finishes its second transaction] C1 -> S: f SAVE uid=7 [SAVE uid=7 depends on dropping [2] lock (currently client 1)] C1 -> S: * UNLOCK [2] (left 0) [SAVEs depending on [2] locks are ordered and forwarded] S -> R: x SAVE uid=7 .. S -> R: y SAVE uid=9 .. The idea is that locks have a counter which is incremented if there was a SAVE command sent after the previous LOCK command. The previous SAVE's UID (prev_uid) is also stored to the lock. When the first SAVE after LOCK arrives, it's assigned a dependency on all existing locks which have uid > prev_uid. The lock counter order doesn't guarantee an ascending prev_uid order. (An actual lock counter probably isn't even needed, prev_uid should be enough as the lock ID. Lock counter simplifies the above example though.) All subsequent SAVEs from the client before the next UNLOCK will have the same dependency as the first SAVE. This is because by that time the transaction has been committed and all messages within the transaction have been given UIDs. So in fact it wouldn't really matter in which order the SAVEs are even sent to the replication sender. Although sending them in order allows an extra optimization: If only a single client is holding a lock, the SAVEs can be immediately forwarded as they're being received. After all lock dependencies have been dropped, it's guaranteed that all new SAVEs will have higher UIDs, so the SAVEs can be ordered and forwarded. A further optimization could use some kind of weak locks that are dropped after the client's first SAVE command. After the weak lock count has dropped to zero, the messages can started to be sent. For example assume two clients having the same lock counter. Both clients would be sending 10000 messages within the same transaction. Waiting for and buffering all of them would waste a lot of memory. Instead it would be possible to read the first SAVE from the first client and then block until the first SAVE is read from the second client. The SAVE with a smaller UID can be forwarded to remote servers. The next message is then read from that connection, and this is continued until all messages have been processed. A simpler solution would have been to order and forward SAVEs only when lock counter dropped to zero, but under very high load it's (at least theoretically) possible that the counter never drops to zero. In synchronous setups (recommended whenever possible) the SAVE commands use a tag (not "*"), which requests an ack reply from the remote. After replication sender has sent SAVE to a remote server, the remote server eventually replies back. This reply is forwarded from replication receiver to sender, which in turn forwards it to the mail process. After mail process has finished sending all SAVEs, it waits until it has received at least one ack for each SAVEd message. If the replication sender sent the SAVE to multiple servers, mail process may receive multiple acks for each message. It should just ignore the ones it doesn't care about. 1.2.2. Modseq updating If all mailbox modifications were done only while the server was the mailbox master, there wouldn't be any problems with modseq updates, because only one server could modify the mailbox at a time. This scales badly though, so it's preferrable to move the master only when absolutely required (for SAVEs) and handle modseqs another ways. Modseqs are incremented by each mailbox modification. All modification commands contain a modseq parameter. When applying the modification command make sure the local modseq is at least as high as the modification command's modseq. If the local modseq is higher, broadcast the new modseq to all other servers using MODSEQ command. When receiving a MODSEQ command, update the modseq only if its current value is lower than the received one. Remember that modseqs can also be updated for expunged messages. All this means that eventually everyone's modseq will be the highest assigned modseq for the change in the cluster. It doesn't matter if temporarily some clients saw lower modseqs. The worst that can happen is that some extra FLAG/MODSEQ updates are sent to the client. Although there is a problem if a client can jump from a server where it had higher modseqs to a server that hadn't yet received the incremented modseqs and performed a sync using the higher modseq. If the updated modseqs come after the sync, they're lost from the client. This could be avoided by issuing a cluster-wide sync wait before such syncing commands are run. 1.2.3. Expunging EXPUNGE commands can be replicated without waiting for anything. There are problems with messages getting expunged while COPY is being handled, but this will be resolved later when COPY is implemented. 1.2.4. Flag updates When STORE is received by a master, it checks if it has higher modseqs in messages than the modseq in STORE parameter. Then it applies all the changes and forwards the changes to other servers using possibly updated modseqs. For messages that had higher initial modseqs their current flags are sent back to the originating server to fix a potential desync. If STORE is initiated by the master, there are no flag desynchronization possibilities. The correctness of applying conflicting changes could be improved by including a "highest modseq of messages before this STORE" parameter. The applying server (master) could then find the flags from that point in time and apply changes on top of it. And finally on the top would be applied newer changes (that were already once applied). There could still be conflicting changes, but the result would be better for updates that had been delayed for a long time. Finding these flag changes and old flag values isn't simple though, so this won't be at least in initial implementation. STORE UNCHANGEDSINCE (CONDSTORE extension) is initially implemented by grabbing a master lock. If there are simultaneous STOREs in other servers, they'll temporarily have lower modseqs and different message flags. Eventually when the STOREs reach the master, they will be applied on top of the CONDSTORE modification. So even if normal STOREs were sent slightly earlier than CONDSTORE, they'd eventually be applied on top of the CONDSTORE change. This makes the STORE UNCHANGEDSINCE work correctly (even if with a slight delay), and our multi-master replication should be fully compatible with the CONDSTORE spec. 1.3. Replication receiving Replication receives 3 different types of data from remote sender: 1. Replies to commands this server's replication sender sent 2. Message texts (as part of SAVE) 3. Metadata updates (SAVEs, STORE, EXPUNGE, etc.) Command replies are handled by directly forwarding them to the replication sender process via a pipe/socket. 1.3.1. Receiving SAVEs The message text part of the SAVE is stored in a file. The file format depends on the server's configured default data format. For now we consider only maildir format where the data is written as-is to the file. This file is later hard linked to the destination maildir directory. If multiple partitions are used, the file should be written to the correct partition. The initial code could write the file to the destination mailbox's tmp/ directory to make sure the partition is correct. There may be some permission problems with this approach though, a separate replication drop directory would be nicer. The rest of the SAVE is processed similarly to other metadata updates. The path to the written file is added as new metadata to the SAVE command. 1.3.2. Metadata updates The primary replication receiver process's job is to read data from the network as fast as possible. Processing the actual updates can take a while, so the work is distributed to multiple worker processes. As discussed above, the primary replication receiver process still writes message texts to files. The workers could do this as well, but it would mean that the text needs to be sent via IPC to the workers, which adds extra overhead. If the message writing really becomes the bottleneck, this change could be done. The replication receiver tries to pass the same user's updates to the same workers so they can benefit from keeping mailboxes open longer. Each worker could be limited to e.g. 100 open mailboxes. The worker handles the SAVE/EXPUNGE/STORE commands using the normal mailbox handling functions. After the changes were successfully committed, commands that had tags are replied as having succeeded. If a change failed, a failure reply is sent instead for it. Replication receiver passes this reply to the replication sender (not to be confused by remote command replies which are also forwarded), which in turn passes it to the originating server. ------ 2. Mailbox synchronization for existing mailboxes. - As described in the replication protocol. - IMAP UID conflict resolution. 3. Mailbox list synchronization. - Track creates, deletes, renames. - Add unique global mailbox ID which is preserved across renames and allows replication to perform renaming (and symlinking?) 4. More features 4.1. Global UIDs - Save GUIDs to messages (dbox: metadata, maildir: dovecot-uidlist) - Tracking GUIDs globally - Implement COPY command - Implement SAVEs sending only global UIDs and FETCHing unknown ones 4.2. Support for untrusted user-run replication processes - Make SAVE and work without being a master - Make CONDSTORE's STORE UNCHANGEDSINCE work without being a master 4.3. Transactions - Wrap changes into transactions just like they're in the originating Dovecot's transaction (e.g. TX-BEGIN, TX-END commands) - On receiving side a transaction is handled in a single Dovecot transaction by a single worker. 4.4. Cluster-wide sync - Broadcast a ping packet and wait for a reply from all servers on the cluster. This ensures that all changes before the ping packet was sent have been received. - Then ping replication receiver process and have it ping worker processes to wait until all received changes have been committed. - CHECK command could do it. - CONDSTORE/QRESYNC commands that take modseq parameters could maybe do it? Or would it be too slow? It would at least increase reliability. We could probably also figure out some rules when the sync is needed and when not. 5. dbox support - Message text can't just be written to a file and renamed. At minimum some dbox metadata needs to be written to it. - Files can't be shared between mailboxes by hard linking like they can be with maildir

[Dovecot] Timeout when using icedove's searching on a large amount of email.
by guillaume.yziquel＠free.fr 05 May '08

05 May '08

Hello list. I'm using dovecot as a local server, where I'm the only user (or so), and I appreciate using icedove searching functionality to roam through the whole inbox in search of some specific string in the body of my emails. Unfortunately, recently, such a search has become impossible, since the search takes too much time, and the connection times out. I've looked throughout the .conf file and the documentation, but I haven't found where I could increase the delay until timeout. If someone knew the right option in the .conf file, it would be really great... Guillaume Yziquel.

I'd like to mirror my dovecot server (which only serves myself). I'm thinking to use gmail. Problem is, I don't want all my mail going to gmail in plain text. I'd like to gpg+mime encrypt each mail using my public key. Any thoughts on how to do this?

Hi. What does the warning "Inotify instance limit for user exceeded, disabling." mean, and how do I get rid of it? I assume that I have to change a limit somewhere? Regards, Anders.

[Dovecot] mail_chroot problems / dovecot 1.1rc4
by Michal Soltys 05 May '08

Hello I've noticed a little strange behaviour of that option. For example with following settings: system user: admin, with its home directory as /home/admin dovecot options: as reported by dovecot -n (in attachment) dovecot will try to chroot into /home/home/admin with the following message in logs, in my case: Fatal: chdir(/home/home/admin) failed with uid 1999: No such file or directory The same happens if I use per-user chroot= option in userdb, f.e. in passwd-file I've noticed it's just now, as I've always used explicit chroot dirs specified through passwd-file with /./ (which works perfectly fine, except harmless double slashes in logs), and didn't bother with single system user (I made some chroot/lock related bugreports in distant 1.0rcXX past).

[Dovecot] libsieve support
by Mateusz Kijowski 05 May '08

05 May '08

Hi, I was wondering - are there any plans on switching the sieve plug-in to use libsieve (http://libsieve.sourceforge.net/)? The rationale of using this library is simple - cmusieve codebase seems stagnant and libsieve promises to implement some new sieve rfc drafts. -- matik

[Dovecot] v1.1.rc5 released
by Timo Sirainen 05 May '08

05 May '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc5.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc5.tar.gz.sig I've finally gone through all my unread mails and fixed most of the reported bugs. There are only a couple ones left that I can't reproduce. Please report if you still have any problems with rc5, even if you already have reported the same bug before. v1.1.rc6 will hopefully be the last RC before v1.1.0. + Support cross-realm Kerberos 5 authentication. Based on patch by Zachary Kotlarek. + Added dict_db_config setting to point to a Berkeley DB config file. + If mail_chroot ends with "/.", remove chroot prefix from home directory. - Fixed several bugs and memory leaks in ACL plugin. LIST and LSUB may have listed mailboxes where user had no 'l' access. STORE could have been used to update any flags without appropriate access. - mbox: Valid-looking From_-lines in message bodies caused the message to be split to two messages (broken since v1.0). - Plugin initialization hooks were called in wrong order, possibly causing problems when multiple plugins were used at the same time. - Expire plugin was broken - LIST-EXTENDED options were ignored. - LDAP: Static attribute names weren't working correctly - deliver: mail_uid and mail_gid settings weren't used. - pop3 + maildir++ quota: maildirsize file wasn't created if it didn't exist already. - dnotify: Waiting for dotlock to be deleted used 100% CPU

[Dovecot] Users w/o acl access appear to be subscribed to public folders (1.1b8)
by Adam McDougall 05 May '08

05 May '08

I noticed this today, I had a user outside of our department test out dovecot. They were using squirrelmail and I noticed that dovecot thinks this user is subscribed to ALL public folders even though a dovecot ACL prevents all access. I'm pretty sure access is still denied. I was able to reproduce this with a guest account I added: l lsub "" "#shared/decs/%" * LSUB (\Noselect) "/" "#shared/decs/linuxadmin" * LSUB (\Noselect) "/" "#shared/decs/jbossadmin" * LSUB () "/" "#shared/decs/support" * LSUB () "/" "#shared/decs/receipts" * LSUB (\Noselect) "/" "#shared/decs/pcadmin" * LSUB () "/" "#shared/decs/network" * LSUB (\Noselect) "/" "#shared/decs/printmaster" * LSUB () "/" "#shared/decs/postmaster" * LSUB (\Noselect) "/" "#shared/decs/unixadmin" * LSUB () "/" "#shared/decs/security" * LSUB (\Noselect) "/" "#shared/decs/webmaster" l OK Lsub completed. This only seems to happen when the acl plugin is enabled. Without the acl plugin, these are not listed as subscriptions. After deleting /egr/mail/shared/decs/dovecot-acl-list and re-enabling the acl plugin, I get this: l lsub "" "#shared/decs/%" * LSUB () "/" "#shared/decs/unixadmin" * LSUB () "/" "#shared/decs/support" * LSUB () "/" "#shared/decs/security" * LSUB () "/" "#shared/decs/printmaster" * LSUB () "/" "#shared/decs/postmaster" * LSUB () "/" "#shared/decs/pcadmin" * LSUB () "/" "#shared/decs/network" * LSUB () "/" "#shared/decs/linuxadmin" * LSUB () "/" "#shared/decs/webmaster" * LSUB () "/" "#shared/decs/jbossadmin" l OK Lsub completed. Is it related, or is it different just because a new dovecot-acl-list got created by another user already (but is mode 700?)

[Dovecot] Compiling plugins
by Juan Asensio Sánchez 05 May '08

05 May '08

Hi I use Debian Etch 4.0r3. I am trying to compile antispam plugin, but i have no idea about how to do it cause i have never done so.

[Dovecot] Dovecot SASL doesn't seem to be working with Postfix
by Jeremy Gillick 05 May '08

05 May '08

I've tried to setup Postfix to use SASL, but it still doesn't seem to be working with Dovecot. I've set things up based on these instructions: http://wiki.dovecot.org/HowTo/SimpleVirtualInstall http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL http://wiki.dovecot.org/LDA I've compiled Postfix with Dovecot SASL and SSL/TLS support. The problems I'm seeing in Postfix are: * Virtual users are not being recognized (it'll only delivers mail for local users) * For mail it does deliver, it uses the local user permissions ( I want it to use the vmail user) * I had to modify 'mail_spool_directory' to get it to use the /home/vmail/ directory * For mail delivered to local users, it still doesn't come up in my email client when I check for new mail. I just keep feeling like the SASL integration is not working. Can anybody shed some light? --- DOVECOT config # 1.0.13: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap pop3 imaps pop3s disable_plaintext_auth: no verbose_ssl: yes login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=postfix gid=postfix home=/home/vmail/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /usr/local/var/run/dovecot/auth-master mode: 384 user: vmail ---- POSTFIX main.cf alias_maps = $alias_database broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 default_privs = nobody html_directory = no inet_interfaces = $myhostname, localhost mail_owner = postfix mail_spool_directory = /home/vmail/ mailq_path = /usr/bin/mailq manpage_directory = /usr/local/man mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = $myhostname myhostname = mixermixer3.com newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix/ readme_directory = no sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_exceptions_networks = $mynetworks smtpd_sasl_local_domain = $myhostname smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_tls_CAfile = /etc/postfix/ssl/smtpd.pem smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.pem smtpd_tls_key_file = /etc/postfix/ssl/smtpd.pem smtpd_tls_loglevel = 1 smtpd_tls_session_cache_timeout = 3600s unknown_local_recipient_reject_code = 550 virtual_mailbox_domains = $myhostname virtual_transport = dovecot ---- POSTFIX master.cf (just the important lines) smtp inet n - n - - smtpd smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} THANKS, Jeremy

[Dovecot] Segfault when opening a public folder, dovecot 1.1 beta4
by Adam McDougall 04 May '08

04 May '08

I was trying to debug this with gdb, but I'm not sure how to make env MAIL=maildir:~/Maildir MAIL_PLUGINS=acl ACL=vfile gdb /tmp/imap understand the #shared/decs namespace from below so I can SELECT it. I have a number of maildirs under #ahared/decs, I tried opening at least 2 of them but dovecot gives sig 11 without a direct error about the problem. I don't think this was exactly the same problem in 1.1b3, but unfortunately I deleted all the patches I was testing with so it would be a pain to test the same situation with 1.1b3 again (although if needed, I can). If dovecot-shared exists in the folder I try to open, dovecot says: Oct 27 12:57:38 gribble dovecot: IMAP(mcdouga9): fchown() failed with file /home/mcdouga9/Maildir/dovecot11testing/public/indexes/decs/.unixadmin/dovecot.index.log: Operation not permitted Oct 27 12:57:38 gribble dovecot: child 55470 (imap) killed with signal 11 I am used to getting the first message because dovecot tries to apply perms from dovecot-shared to the index files which are elsewhere. If I open a public folder without dovecot-shared, I see no contents but it does not sig11. I am NOT using the acl plugin right now, it didn't seem to make a difference if it was loaded. When I left off with the dovecot 1.1b3 + 8 patches, I believe I was getting an assertion. Please let me know if I goofed up something, I have a strange feeling about that here, or if you need more info. I'd like to go ahead and get a gdb trace. # 1.1.beta4: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/cert.pem ssl_key_file: /usr/local/etc/apache2/ssl/cert.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot11testing/private/control:INDEX=%h/Maildir/dovecot11testing/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot11testing/public/control/decs:INDEX=%h/Maildir/dovecot11testing/public/indexes/decs list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot11testing/private/control:INDEX=%h/Maildir/dovecot11testing/private/indexes hidden: yes subscriptions: yes namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] FAQ: setting thunderbird to talk to dovecot
by Mauricio Tavares 04 May '08

04 May '08

Let's say I have a postfix box, named mail.thespider.com, which is setup to handle virtual mailbox domains. One of these domains will handle is, thespider.com, and my email address in that domain is boris(a)thespider.com. As I setup dovecot, I can telnet to the pop3 port (110) and test it by logging in as boris(a)thespider.com (I would try the imap port but I do not know how to login to imap from the telnet prompt): [raub@taz ~]$ telnet mail.thespider.com 110 Trying 192.168.1.12... Connected to mail.thespider.com (192.168.1.12). Escape character is '^]'. +OK dovecot ready. user boris(a)thespider.com +OK pass creepycrawly +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [raub@taz ~]$ How would I do the same under thunderbird from a machine in the same lan (taz.thespider.com)? It seems to keep trying to login as boris(a)mail.thespider.com, which will not fly.

[Dovecot] UID inserted in the middle of mailbox errors
by Dean Brooks 04 May '08

04 May '08

Hi, We are still getting, on a daily basis, users who cannot move messages to Trash or expunge Trash due to these errors: Mar 28 10:43:57 tm2 dovecot: [ID 107833 mail.error] IMAP(kss021): mbox sync: UID inserted in the middle of mailbox /home/kss021/Mail/Trash (3137 > 536, seq=2, idx_msgs=76) Our users have no other access to their mailbox other than Dovecot, and we are using mbox format and 1.1rc3. Deleting the indexes fixes the problem, so it seems to be a problem with index corruption and not something inherently wrong with the mailbox. That is, once I delete the index files, the problem does not come back immediately. I've seen others on the list with the same problem, but I wasn't able to find a workaround. It's happening more and more frequently. I guess what I don't understand is why Dovecot cant just mark the index invalid and purge it instead of failing over and over. I thought the whole point behind Dovecot's indexing is that it was able to detect index inconsistencies and mark the index invalid. Any help is much appreciated. Even a quick stopgap fix would be a lifesaver, short of a cronjob that just purges everyone's index files every 2 hours (which sort of defeats the point of using Dovecot). -- Dean Brooks dean(a)iglou.com

[Dovecot] Embedded From_ lines breaking Content-Length (and Dovecot)
by Lennart Lövstrand 04 May '08

04 May '08

I feel like I'm going totally crazy. Is it just me, or have embedded From_ lines really been breaking mbox messages since (at least) dovecot 1.0? I found a whole lot of broken messages in an old mailbox of mine and when I looked closer at it, it seemed like Dovecot was ignoring the Content-Length header and truncating the messages at the first embedded From_ line instead. Figuring that this probably just was a fluke / old bug, I erased the index and upgraded Dovecot, first to 1.0.10, then to 1.1.beta14, but I'm still seeing the bug -- and it's even gotten worse! Earlier versions would just quietly split the message at the From_ line, but 1.1.beta14 is more diligent and will complain with: > dovecot[44795]: IMAP(lennart): FETCH for mailbox Drafts UID 196 got > too little data: 590 vs 719 before dropping the connection and exiting... which cause Thunderbird to reopen the connection and reissue the same request... which will cause Dovecot to complain and exit again... etc ad nauseam... It's trivial to reproduce too -- just mail yourself a message with a valid From_ line in it (assuming that your delivery system isn't doing >From-escaping), or put it in a draft plain text message and save it. Then go and look in your Drafts folder... (Like this one: "From someone Tue Jan 29 03:15:52 2008") Just be sure that you can stop your spinning mail client and/or server if you're using 1.1.beta14... --- OK, I am definitely not very familiar with the Dovecot source, but I spent some time trying to track this down today and it looks to me like i_stream_raw_mbox_read is being asked to find the end of the message (at the From_ line) before mbox_sync_parse_next_mail has had a chance to parse the Content-Length header and find out how big it is. Maybe someone who knows the code better can take a look at it and tell me if I'm barking up the totally wrong tree... Thanks, --Lennart

[Dovecot] Mailbox locking issue?
by Mark Sapiro 04 May '08

04 May '08

Here's my configuration. dovecot -n # 1.0.7: /usr/local/etc/dovecot.conf protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: /var/spool/mail/%u mbox_write_locks: fcntl dotlock The above setting was just added in an attempt to resolve the issue. It was default before. mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Postfix 2.3.3 mailbox_delivery_lock = fcntl, dotlock The problem is the following. A user uses fetchmail via an ssh tunnel to download mail via pop3 every 5 minutes. This normally works fine. perhaps once a week or so, maillog shows that Postfix delivers a message while fetchmail is retrieving. Here is one such. Apr 8 19:07:20 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured Apr 8 19:07:22 sbh16 postfix/local[13745]: D959169046B: to=xxx(a)example.com>, orig_to=<xxx(a)example.org>, relay=local, delay=16, delays=15/0/0/1.1, dsn=2.0.0, status=sent (delivered to mailbox) Apr 8 19:07:22 sbh16 dovecot: POP3(xxx): Disconnected: Logged out top=2/15995, retr=0/0, del=2/2, size=15985 Five minutes later when fetchmail comes back, we see Apr 8 19:12:42 sbh16 dovecot: POP3(xxx): mbox sync: Expunged message reappeared in mailbox /var/spool/mail/xxx (UID 4683 < 4684, seq=2, idx_msgs=0) Apr 8 19:12:42 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured Apr 8 19:12:46 sbh16 dovecot: POP3(xxx): mbox sync: UID inserted in the middle of mailbox /var/spool/mail/xxx (4684 > 4683, seq=2, idx_msgs=1) Apr 8 19:12:46 sbh16 dovecot: POP3(xxx): Disconnected: Logged out top=1/46375, retr=0/0, del=1/1, size=46365 >From now on, as messages are added to the mailbox by Postfix, fetchmail keeps retrieving both old and new messages. i.e. even though dovecot's log says del 1/1 (or del n/n) no messages are actually deleted from the mailbox. This situation continues until someone accesses the mailbox locally (e.g. via mutt through a local shell) and deletes the old messages. As noted above, this has been observed a few times with dovecot's default mbox_write_locks. I have since changed that to mbox_write_locks: fcntl dotlock to be consistent with Postfix's mailbox_delivery_lock = fcntl, dotlock I don't know if that will fix the problem or not, but it seems the issue with default dovecot mbox_write_locks should have been deadlock and time out rather than what we see. Also it seems that dovecot should recover from the 'corrupt' mailbox and fix it rather than just continuing to encounter the same problem. Any ideas or advice? -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

My migration happens like this: - if a user receives mail (before ever using the new mail system), it goes to his/her inbox, dovecot proceeds normally, like when a user exists, but never received mails. Quota is shown ok. - if a user logs in before receiving any new mail, then, /var/spool/data/USER/new is created, and all converted messages are copied to that dir. If that user had deleted messages (some users mark messages as deleted, others delete for real), then a /var/spool/data/USER/.Trash/new dir is created, and messages are put there too. No other files/dirs (dovecot-uidlist maildirsize cur tmp), are created by "me" or the migration scripts. Index files (/var/spool/index/USER) are not created neither. They are created by dovecot itself. I have a problem, when a user has mails that exceed the limit in mb's (I set just size limit, no messages limit), neither "getquotaroot" (via telnet to port 143), neither webmail software (horde) show the quota usage correctly (I'm not talking about new mail, talking about those messages copied, when they exceed the size limit). Just after trying to delete messages it is shown (gives me an error message, quota exceeded, since Trash is not excluded from quota limits, for now, I'll exclude it later). This server has some issues: many old users have lots of mails, in thousands (1000-15000). Some have 50mb to 150mb of mails. The migration is part of the cleanup process. --- MY QUESTIONS --- Is it possible that the migration order (creating dirs in that way) is causing the quota usage to be shown wrong? Is it possible that the amount of messages and the size can be the cause? Misconfiguration? Other causes? How can I manually tell dovecot to recalculate the quota, after copying messages (when a user logs in, and didn't receive new mails on the new mail system, but had messages big enough to exceed the quota limit) from the old system? Should I run any commands to rebuild indexes or any operation to keep information integrity about the mails/mailboxes to dovecot, after copying the converted messages? many thanks = -- Powered by Outblaze

[Dovecot] Master user and missing folders
by Anders 04 May '08

04 May '08

Hello again. I am trying to use a master user. The login works. However, a LIST command gives me only the INBOX. Is this to be expected? When logging in normally, I do get the full list of folders. (using Dovecot 1.1 rc3.) Anders.

[Dovecot] The CONTROL problem with fs quotas.
by Jorgen Lundman 04 May '08

04 May '08

dovecot-1.0.10 on Solaris 10 x86, with NFS. We currently have the problem that when customers go over their disk quota, the dovecot-uidlist file stops them from logging in. In the interest of solving it, we considered moving the CONTROL file to a different file system. But: 1: Using CONTROL= with "%u" will quite quickly run into the problem that the directory will fill up, and hit the maximum (around 32k) or so. We have 170k users so far, and more are being imported. You could cull some from crontab or similar, but is generally a poor way to solve a problem. 2: We attempted to use CONTROL= with "%h", which would give us full directory hashing, however, we found that when it creates all the directories, it does so as the uid of the first user. So all following users (that hash in at least one part) will fail. Most likely because dovecot has already setuid()ed. Pre-creating the hashes is not feasible. 3: Using 2, we could change umask to "0000" and hence it does not matter than all directory hash node are owned by a user's id, but this unfortunately includes all other directories, and having all directories at 777 is not an option. Now, naturally, I can easily patch dovecot to call mkdir_parents with 0777 only for CONTROL. But I would rather not have local patches, meaning upgrades will be difficult. It would be preferable if: => Dovecot would call "mkdir_parents" on "%h" _before_ setuid, but create the final directory after. OR, Dovecot support (at least 2 level) directory hashing when specifying CONTROL=%1/%2/%u OR, The ability to disable dovecot-uidlist (in memory is fine). (Setting INDEX=memory does not work for CONTROL=). Are there other solutions out there? -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] used_file_size too large
by Anders 04 May '08

04 May '08

Hi. Just got this error (1.1.rc4), is it something to worry about? Corrupted index cache file /.../Maildir/.Sent/dovecot.index.cache: used_file_size too large This is a shared mailbox with concurrent access. In general, can that usage pattern mess up the index? I am guessing "no", which is why I worry slightly about the warning. Cheers, Anders.

[Dovecot] Can't receive mail for virtual user

I followed the dovecot instructions ( http://wiki.dovecot.org/HowTo/SimpleVirtualInstall) to create a simple virtual user installation with the /etc/dovecot/passwd file.

[Dovecot] Dovecot 1.1: Ignoring Trash/Junk for maildirsize?
by richs＠whidbey.net 04 May '08

04 May '08

Hi all, We're testing Dovecot 1.1rc3, but have run into a snag with IMAP Quota's and the way Trash and Junk folders can be handled. Our MTA (Exim) quota configuration uses this option: maildir_quota_directory_regex = ^(?:cur|new|\.(?!Junk$)(?!Trash$).*)$ This completely excludes "Junk" and "Trash" from the "maildirsize" file and quota calculations. Dovecot 1.0 could do this using "ignore=Trash" (although only on one folder). Is there any way to duplicate this behavior in Dovecot 1.1? We see that "quota_rule" can be used to set an unlimited quota (storage=0), but for some reason Dovecot still records their tallies in "maildirsize", which breaks the MTA. Thanks! -Rich

[Dovecot] Patch for zlib and maildir for 1.0.13
by Richard Platel 04 May '08

04 May '08

When using the zlib plugin with maildir and copying with hardlinks, if a compressed message is copied, the 'Z' suffix on the file isn't copied, so the new message isn't uncompressed when it's fetched. I wasn't smart enough to figure out a clean way to carry a file suffix through a copy, so I changed how the zlib-plugin detects if a message is compressed. This patch peeks at the first two bytes of the message looking for the zlib header. -- Richard Platel Tucows

[Dovecot] 1.1rc4 problem with maildir++ quota and POP3
by Laurent Papier 04 May '08

04 May '08

Hi, it looks like there is a bug (in dovecot or in my config) with quota on maildir mailboxes when accessed via POP3. The maildirsize is not created when not already present (even after a DELE + QUIT command). The quota limit (the first line of maildirsize) is not updated if values are not in sync with those in the database. If maildirsize is present, DELE commands are correctly reported in maildirsize. maildirsize is correctly updated when the same mailbox is accessed in IMAP or mail is delivered with dovecot LDA. Here is my config. Timo 'dovecot -n' does not show the lda config part... # 1.1.rc4: /etc/dovecot.conf protocols: imap pop3 ssl_disable: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: please to meet you login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_processes_count: 100 login_max_processes_count: 512 max_mail_processes: 3072 mail_uid: 1000 mail_gid: 1000 mail_location: maildir:~/ mmap_disable: yes maildir_stat_dirs: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): imap_quota quota mail_plugins(imap): imap_quota quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls auth default: user: nobody passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: prefetch socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: mailonly group: mailonly plugin: quota: maildir quota_rule2: Trash:storage=12288:messages=100 --- SQL queries ---- # prefetch auth password_query = SELECT cpasswd as password, home as userdb_home, concat('*:bytes=',quotas,':messages=',quotai) AS userdb_quota_rule FROM `mail` WHERE email='%u' # for delivery user_query = SELECT home, concat('*:bytes=',quotas,':messages=',quotai) AS quota_rule FROM `mail` WHERE email='%u' -- Laurent Papier - 03 88 75 80 50 Admin. système - SdV Plurimedia - <http://www.sdv.fr/>

[Dovecot] deliver: handling of quota_full_tempfail and -e
by Ulrich Zehl 04 May '08

04 May '08

Hi, while testing out dovecot 1.1, I found that when you set quota_full_tempfail = yes in dovecot.conf and use the deliver -e command line flag, no deferral reason is printed, thus breaking my fancy quota_exceeded_message. This appears to be because of the if() block in lines 1003-1009 in src/deliver/deliver.c, and should be easily fixable (if it is indeed a bug, and not intended behavior). However, I shied away from creating a patch because either there is a mismatch between the documentation and deliver's actual behavior, or I misunderstood the code (likely, since I'm not really a C programmer). The lines in question (in src/deliver/deliver.c) read: | 1003 if (error != MAIL_ERROR_NOSPACE || | 1004 getenv("QUOTA_FULL_TEMPFAIL") != NULL) { Does this mean that the corresponding block gets executed whenever quota_full_tempfail is set? If so, setting it transforms all errors into TEMPFAILs, and not only those relating to quota/space issues. I think dovecot-example.conf should at least mention this it's inteded; otherwise, the code should be changed (I'm not completely sure what Timo's intensions are, so I won't comment on possible solutions). Regards, Ulrich PS: All line numbers are taken from rev 080dd4d2fd94, which was the most recent at the time of writing.

[Dovecot] Replication protocol design
by Timo Sirainen 03 May '08

03 May '08

I'll probably be implementing multi-master replication this summer. My previous thoughts about it are here: http://dovecot.org/list/dovecot/2007-December/027284.html Below is a description of how the replication protocol will probably work. It should work just as well for master-slave and multi-master setups. Comments welcome. I'll write later a separate mail about how it'll be implemented to Dovecot. Goals ----- 1. If a single (or configurable number of) server dies, no mails must be lost that have been reported to IMAP/SMTP clients as being successfully stored. 2. Must be able to automatically recover from a server desynchronization, such as: - server has been offline for a long time - some mail files have been manually added/deleted - corrupted data/mail files if they're noticed 3. In multi-master setup if the link between servers die, the servers must be able to proceed autonomously (kind of conflicts with goal 1 though). When the link comes back, the changes are replicated as soon as possible. 4. Normal IMAP commands must not be able to cause desynchronization between servers. For example making conflicting flag changes simultaneously in two servers must not result in the servers having different flags. 5. Must perform well with at least 3 servers in a multi-master setup, preferrably still with tens of servers. 6. Latency shouldn't be increased noticeably when using servers distributed into 3 or more data centers. Must be usable over high-latency links (in optimistic async mode). 7. In normal operation send minimal incremental changes. Protocol -------- There are two major parts in the protocol: Handling the normal incremental changes and fixing desynchronization. Originally I thought that maybe the changes could be sent using the same format as Dovecot's transaction logs, but now I'm beginning to think that it's probably not that good idea. The code reuse potential is quite minimal and the format would still have to be extended in several ways so that it won't be directly compatible anyway. So I'm thinking the protocol could be something text-based. The main benefit is that text-based protocols are easier to debug. Stream compression should drop most of the extra overhead if bandwidth is a problem. The exact on-wire protocol anyway doesn't matter in the design that's discussed below. The commands have tags similar to IMAP commands, because some commands may have to be forwarded to other servers and it may take a while to get a reply. During the wait the server may process other commands. Mailbox master -------------- Each mailbox has a single master server selected. In multi-master setups the master server may be moved by having the destination server simply request it from the current master. The current master must then give it up. If link is lost to the current master, one of the remaining servers will become the new master within the remaining servers. Each server must be connected to the current master server. Since each mailbox can have a different master server, this typically means all servers are connected to each others. However it's possible to create setups where server connects to only one other server, which in turn connect to more servers. This is useful if there are bandwidth bottlenecks between some servers. This kind of a situation can also happen if in a network A-B-C the link A-C dies, but A-B and B-C continues to work. Because of this all commands must be able to function in a way that the server proxies them to the current master, instead of failing the command and trying to make it the caller's problem to resend the command to the actual master. When the cluster starts up, a single server is selected as the root master for all mailboxes. If a server doesn't know who the current mailbox master is, it asks from the root. All servers cache the currently known mailbox masters to avoid constant requests to the root. If the root server dies, another server is selected as the root. Because the new root doesn't know what masters have been requested (and asking all of them from all servers would just waste bandwidth), all the servers are expected to flush their master caches and drop their own master status. The new root doesn't respond to any requests before all servers have notified that they've dropped being a master. The master status doesn't have to be at mailbox level granularity. It could just as well be configured to move at user, domain or even global level. Perhaps this could be done dynamically, so that higher granularity is used when the master is beginning to change too often between servers. Mailbox ID ---------- Mailbox IDs are session-specific numbers dynamically assigned for user+mailbox+UIDVALIDITY combinations. All connections have different mailbox IDs. Also send and receive directions have different IDs. This allows the sender to easily replace existing IDs to point to new mailboxes without causing any confusion. MBOX: - Mailbox ID - User name - Mailbox name - Mailbox UIDVALIDITY - Mailbox UIDNEXT - Mailbox message count If the receiver finds out it has a different UIDVALIDITY, the mailbox requires a full resync. Message count and UIDNEXT may also be used to determine if replication servers are out of sync. Requesting master status ------------------------ MASTER-MOVE: - Mailbox ID - [Destination SID] (if forwarding) The command is sent to the last known master for the mailbox. The server will keep forwarding the command until it reaches the current master. During the forwarding other servers may want to request something from the master. These requests must be delayed by the forwarding servers until the move is finished. Saving messages --------------- SAVE: - Mailbox IDs - Received date - [IMAP UID] (only if we're the master) - Global UID (stays the same when copying the message) - Message text Reply: - [IMAP UID] (only if not specified in parameters) - [Current mailbox master SID] (if it was moved) If current server is not the master, the SAVE is sent to the master which gives the message its UID. The master server then replicates the message to other servers with the UID parameter set. The mailbox master may have already changed by the time server receives a save request. If server receives a SAVE without IMAP UID parameter, it's responsible for finding out the new mailbox master and sending a new SAVE request to it. Once the new master replies with the IMAP UID, the server can reply to the original SAVE request, also providing the new master SID so the future requests can be sent there directly. To be sure the message doesn't get lost, the server should not reply OK to the IMAP/SMTP client until it has received a reply from SAVE. Copying messages ---------------- COPY: - Source mailbox ID - Destination mailbox ID - Source IMAP UID - Global UID - [Destination IMAP UID] (only if we're the master) - Destination received date Reply: - [Destination IMAP UID] (only if not specified in parameters) - [Current mailbox master SID] (if it was moved) Source mailbox ID + source IMAP UID identifies the message to be copied. It's expected to contain the given global UID (which is just an extra sanity check). Otherwise it works the same way as SAVE. Since the message already exists, it's probably not necessary to wait for a reply before replying OK to originating IMAP client. Expunging messages ------------------ EXPUNGE: - Mailbox ID - UID range (No reply) Expunges also have to be sent via master server (the same way as SAVE) to avoid COPY command failing in some servers because it was just expunged. Changing message flags ---------------------- STORE: - Mailbox ID - UID range - Added flags/keywords - Removed flags/keywords - [Current modseq] (master sends) - [Highest modseq of the messages before this change] (non-master sends) - [flag: this is a CONDSTORE STORE UNCHANGEDSINCE] (non-master may send) [Reply: - UIDs where STORE was rejected to (if CONDSTORE flag was used) ] Stores also have to be sent via master server to avoid flag desynchronization. Master first checks if it has higher modseqs in the messages. Then it applies all the changes and forwards the changes to other servers. For messages that had higher initial modseqs their flags are sent to the server sending the STORE to fix a potential desync. If CONDSTORE flag is set, the change is rejected for messages that had a higher modseq. Non-masters shouldn't reply to a STORE UNCHANGEDSINCE command before the change has been replicated to master and the rejections have been processed. Mailbox synchronization ----------------------- If a mailbox is determined to have changed externally (e.g. network connection down for too long, causing replication logs to get full) the mailbox state needs to be synchronized between servers. SYNC: - UIDVALIDITY - UIDNEXT - Message count - For each message: - UID - Global UID - Modseq - Flags and keywords - Received date Reply: - (Sync finished) Receiving server compares the parameters with its own mailbox state. If it finds previously unseen global UIDs, their message texts are requested: FETCH: - Mailbox ID - UID Reply: - Message text SAVE, EXPUNGE and STORE commands are used to synchronize the mailbox. A special case is when two servers have been saving messages independently from each others. In this case it's possible that the servers have used the same UIDs for different messages (different global UIDs). These need to be resolved by giving both conflicting UIDs new unused UIDs, otherwise IMAP clients may show them as wrong messages from their caches. FIXME: If the other server had expunged a conflicting UID it still should be given a new UID. How do we find out this has happened?

[Dovecot] Replication protocol design #2
by Timo Sirainen 01 May '08

01 May '08

Changes: - Added goal 8 and rewrote mailbox synchronization plan. - Added new SELECT command to change active mailbox and removed mailbox ID from command parameters Goals ----- 1. If a single (or configurable number of) server dies, no mails must be lost that have been reported to IMAP/SMTP clients as being successfully stored. 2. Must be able to automatically recover from a server desynchronization, such as: - server has been offline for a long time - some mail files have been manually added/deleted - corrupted data/mail files if they're noticed 3. In multi-master setup if the link between servers die, the servers must be able to proceed autonomously (kind of conflicts with goal 1 though). When the link comes back, the changes are replicated as soon as possible. 4. Normal IMAP commands must not be able to cause desynchronization between servers. For example making conflicting flag changes simultaneously in two servers must not result in the servers having different flags. 5. Must perform well with at least 3 servers in a multi-master setup, preferrably still with tens of servers. 6. Latency shouldn't be increased noticeably when using servers distributed into 3 or more data centers. Must be usable over high-latency links (in optimistic async mode). 7. In normal operation send minimal incremental changes. 8. Make non-incremental synchronization fast enough to allow replication with users' untrusted Dovecot servers which may connect only rarely. Support also super high latency replication (e.g. using USB sticks). Protocol -------- There are two major parts in the protocol: Handling the normal incremental changes and fixing desynchronization. Originally I thought that maybe the changes could be sent using the same format as Dovecot's transaction logs, but now I'm beginning to think that it's probably not that good idea. The code reuse potential is quite minimal and the format would still have to be extended in several ways so that it won't be directly compatible anyway. So I'm thinking the protocol could be something text-based. The main benefit is that text-based protocols are easier to debug. Stream compression should drop most of the extra overhead if bandwidth is a problem. The exact on-wire protocol anyway doesn't matter in the design that's discussed below. The commands have tags similar to IMAP commands, because some commands may have to be forwarded to other servers and it may take a while to get a reply. During the wait the server may process other commands. Mailbox master -------------- Each mailbox has a single master server selected. In multi-master setups the master server may be moved by having the destination server simply request it from the current master. The current master must then give it up. If link is lost to the current master, one of the remaining servers will become the new master within the remaining servers. Each server must be connected to the current master server. Since each mailbox can have a different master server, this typically means all servers are connected to each others. However it's possible to create setups where server connects to only one other server, which in turn connect to more servers. This is useful if there are bandwidth bottlenecks between some servers. This kind of a situation can also happen if in a network A-B-C the link A-C dies, but A-B and B-C continues to work. Because of this all commands must be able to function in a way that the server proxies them to the current master, instead of failing the command and trying to make it the caller's problem to resend the command to the actual master. When the cluster starts up, a single server is selected as the root master for all mailboxes. If a server doesn't know who the current mailbox master is, it asks from the root. All servers cache the currently known mailbox masters to avoid constant requests to the root. If the root server dies, another server is selected as the root. Because the new root doesn't know what masters have been requested (and asking all of them from all servers would just waste bandwidth), all the servers are expected to flush their master caches and drop their own master status. The new root doesn't respond to any requests before all servers have notified that they've dropped being a master. The master status doesn't have to be at mailbox level granularity. It could just as well be configured to move at user, domain or even global level. Perhaps this could be done dynamically, so that higher granularity is used when the master is beginning to change too often between servers. Mailbox ID ---------- Mailbox IDs are session-specific numbers dynamically assigned for user+mailbox+UIDVALIDITY combinations. All connections have different mailbox IDs. Also send and receive directions have different IDs. This allows the sender to easily replace existing IDs to point to new mailboxes without causing any confusion. MBOX: - Mailbox ID - User name - Mailbox name - Mailbox UIDVALIDITY Reply: - [Mailbox UIDVALIDITY] (if changed - command failed) - Mailbox UIDNEXT - Highest modseq If the receiver finds out it has a different UIDVALIDITY, the mailbox requires a full resync. UIDNEXT and modseq can be used to determine if replication servers are out of sync. After mailbox ID has been assigned, the active mailbox can be changed using a command: SELECT: - Mailbox ID Requesting master status ------------------------ MASTER-MOVE: - [Destination SID] (if forwarding) The command is sent to the last known master for the selected mailbox. The server will keep forwarding the command until it reaches the current master. During the forwarding other servers may want to request something from the master. These requests must be delayed by the forwarding servers until the move is finished. Saving messages --------------- SAVE: - Received date - [IMAP UID] (only if we're the master) - Global UID (stays the same when copying the message) - Message text Reply: - [IMAP UID] (only if not specified in parameters) - [Current mailbox master SID] (if it was moved) If current server is not the master, the SAVE is sent to the master which gives the message its IMAP UID. The master server then replicates the message to other servers with the IMAP UID parameter set. The mailbox master may have already changed by the time server receives a save request. If server receives a SAVE without IMAP UID parameter, it's responsible for finding out the new mailbox master and sending a new SAVE request to it. Once the new master replies with the IMAP UID, the server can reply to the original SAVE request, also providing the new master SID so the future requests can be sent there directly. To be sure the message doesn't get lost, the server should not reply OK to the IMAP/SMTP client until it has received a reply from SAVE. Copying messages ---------------- FIXME: Source or destination mailbox ID parameter should probably be removed and the selected mailbox's ID used instead. COPY: - Source mailbox ID - Destination mailbox ID - Source IMAP UID - Global UID - [Destination IMAP UID] (only if we're the master) - Destination received date Reply: - [Destination IMAP UID] (only if not specified in parameters) - [Current mailbox master SID] (if it was moved) Source mailbox ID + source IMAP UID identifies the message to be copied. It's expected to contain the given global UID (which is just an extra sanity check). Otherwise it works the same way as SAVE. Since the message already exists, it's probably not necessary to wait for a reply before replying OK to originating IMAP client. Expunging messages ------------------ EXPUNGE: - IMAP UIDs (No reply) Expunges also have to be sent via master server (the same way as SAVE) to avoid COPY command failing in some servers because it was just expunged. Changing message flags ---------------------- STORE: - IMAP UIDs - Added flags/keywords - Removed flags/keywords - [Current modseq] (master sends) - [Highest modseq of the messages before this change] (non-master sends) - [flag: this is a CONDSTORE STORE UNCHANGEDSINCE] (non-master may send) [Reply: - IMAP UIDs where STORE was rejected to (if CONDSTORE flag was used) ] Stores also have to be sent via master server to avoid flag desynchronization. Master first checks if it has higher modseqs in the messages. Then it applies all the changes and forwards the changes to other servers. For messages that had higher initial modseqs their flags are sent to the server sending the STORE to fix a potential desync. If CONDSTORE flag is set, the change is rejected for messages that had a higher modseq. Non-masters shouldn't reply to a STORE UNCHANGEDSINCE command before the change has been replicated to master and the rejections have been processed. Mailbox synchronization ----------------------- Network connections to other servers are always initiated by the same servers. From replication point of view they could be thought of as client/server. The clients keep track of the last seen server state for all mailboxes: - UIDVALIDITY - UIDNEXT - Highest modseq Client requests mailbox ID with MBOX command. If UIDVALIDITY changed, state is reset by setting UIDNEXT=1 and highest modseq=0. MBOX command is then resent using the updated UIDVALIDITY. If server's UIDNEXT (server-UIDNEXT) is higher than last seen UIDNEXT (old-UIDNEXT), it means the server has added new messages and we want to fetch them. If the client's UIDNEXT (client-UIDNEXT) is higher than the old-UIDNEXT, it means the client has added new messages and they need to be sent to the server. All messages with UID >= old-UIDNEXT and UID < min(client-UIDNEXT, server-UIDNEXT) have an UID conflict and they must be given new unused UIDs. The synchronization is done in two batches of commands. Client first selects the mailbox and then starts the sync: SYNC-BEGIN: - server's last highest modseq - client's current highest modseq - QRESYNC-like sequence + IMAP UID lists for optimizing EXPUNGE replies Client then proceeds to send all its changes using SAVE, EXPUNGE and STORE commands. The sync is finished with SYNC-END command. Server replies with: - List of expunged IMAP UIDs (EXPUNGE command): - IMAP UIDs - Added messages (SAVE command?): - IMAP UID - Global UID - Modseq - Flags and keywords - Received date - [Message text] - Changed flags/keywords/modseqs (STORE commands): - IMAP UID - Modseq - Changed flags and keywords (or if not easily determined, their current values) - IMAP UID conflict fixes (UIDFIX command): - Source IMAP UIDs - Destination IMAP UIDs - Sync finish: - Updated UIDNEXT - Updated highest modseq Server may also reply with STORE commands that change nothing except modseqs. This is needed to get the modseqs synchronized. If in high-latency + high-bandwidth mode the message texts are always sent. The message texts are also sent if the server can determine that the client couldn't have previously seen the message (i.e. the message was saved, not copied). Otherwise they have to be requested for the messages with previously unseen global UIDs: FETCH: - IMAP UIDs Reply: - Message texts By the time client receives the reply from server, it may already have done further changes. This means it may have to fix modseqs and IMAP UIDs internally as well.

[Dovecot] virtual mbox case sensitive?
by Anil 01 May '08

01 May '08

This is on dovecot 1.1.rc4. I have this mail_location: mail_location = maildir:/apps/mail/%d/%n/Maildir When I receve mail to a virtual mailbox, its putting it in different Maildir's depending on what the sender used for the caseness of the recipient's email address: I have these Maildirs: JasonK JuliaM info jasonk juliam JasonK and jasonk should be the same maildir. So should JuliaM and juliam. Now the 2nd question is, how do I "move" the mail from JasonK back to jasonk? Thanks, this is very odd!

[Dovecot] Avelsieve 1.9.7 and Dovecot/TLS
by Michael Firnau 30 Apr '08

30 Apr '08

Hi, i'm installing a new mail server for our faculty and want to use the squirrelmail plugin 'avelsieve' (1.9.7). As documented on the dovecot wiki there is a problem in the STARTTLS code and i found a solution (that works for my installation): i've traced the server output in 'get_response' and instead of a script list i saw "IMPLEMENTATION". So i took a look at the file 'managesieve.lib.php' and the STARTTLS code: /* If we allow STARTTLS, use it */ if($this->capabilities['starttls'] === true && function_exists('stream_socket_enable_crypto') === true) { fputs($this->fp,"STARTTLS\r\n"); $starttls_response = $this->line=fgets($this->fp,1024); if(stream_socket_enable_crypto($this->fp, true, STREAM_CRYPTO_METHOD_TLS_CLIENT) == false) { $this->error=EC_UNKNOWN; $this->error_raw = "Failed to establish TLS connection."; return false; } else { $this->loggedin = true; // RFC says that we need to ask for the capabilities again $this->sieve_get_capability(); $this->loggedin = false; } } With my limited time and debugging possibilities i've found that the dovecot managesieve server seems to send capability lines 'automagically'. I've added a few "debugging" lines /* If we allow STARTTLS, use it */ if($this->capabilities['starttls'] === true && function_exists('stream_socket_enable_crypto') === true) { fputs($this->fp,"STARTTLS\r\n"); $starttls_response = $this->line=fgets($this->fp,1024); if(stream_socket_enable_crypto($this->fp, true, STREAM_CRYPTO_METHOD_TLS_CLIENT) == false) { $this->error=EC_UNKNOWN; $this->error_raw = "Failed to establish TLS connection."; return false; } else { $this->loggedin = true; $starttls_response = $this->line=fgets($this->fp,1024); $errormsg .= _("MFI fgets ") . $starttls_response . '<br>'; print_errormsg($errormsg); // RFC says that we need to ask for the capabilities again $this->sieve_get_capability(); $this->loggedin = false; } } and could read MFI fgets "IMPLEMENTATION" "dovecot" what will throw the following 'sieve_get_capability' out of sync. Then i've added a second 'fgets' and received: MFI fgets "SASL" "PLAIN" Then i've added a third 'fgets' and received: MFI fgets "SIEVE" "fileinto reject envelope vacation imapflags notify subaddress relational comparator-i;ascii-numeric regex" Then i've added a fourth 'fgets' and received: MFI fgets OK "TLS negotiation successful." Now the protocol should be in sync again and after removing the lines $errormsg .= _("MFI 1 fgets ") . $starttls_response . '<br>'; print_errormsg($errormsg); i could load my scripts back. So, adding four lines reading $starttls_response = $this->line=fgets($this->fp,1024); $starttls_response = $this->line=fgets($this->fp,1024); $starttls_response = $this->line=fgets($this->fp,1024); $starttls_response = $this->line=fgets($this->fp,1024); solved the problem. I know this is not a sound "fix", but i hope to help you with this. One addendum: a "debugging" using my errormsg-printout of the output from /* If we allow STARTTLS, use it */ if($this->capabilities['starttls'] === true && function_exists('stream_socket_enable_crypto') === true) { fputs($this->fp,"STARTTLS\r\n"); $starttls_response = $this->line=fgets($this->fp,1024); resulted in the response: MFI fgets OK "Begin TLS negotiation now." what looks proper to me, but the negotiation makes the server send the four lines mentioned above. Cheers

[Dovecot] Broken Header uidvalidity problem after upgrade
by Robert Henjes 30 Apr '08

30 Apr '08

Hi, we use a current Debian etch distribution as basis for our servers, which are running within a vmware server environment. Our current configuration consists of a dovecot server with imap enabled and a ldap based authentication. Mails are stored using the Maildir format on a central nfs store. We do not use any virtual mailboxes. Since upgrading from dovecot version 1.0.rc15 (debian stable) to 1.0.13 (debian etch-backport) we got the following error logs. Excerpt from mail.err: Apr 21 12:04:38 servera deliver(usera): /var/mail/Maildir/usera/dovecot-uidlist: Broken header (uidvalidity = 0, next_uid=9) Apr 21 15:37:50 servera deliver(userb): /var/mail/Maildir/userb/dovecot-uidlist: Broken header (uidvalidity = 0, next_uid=16) Apr 23 10:37:17 servera dovecot: IMAP(userc): /var/mail/Maildir/userc/.Sent/dovecot-uidlist: Broken header (uidvalidity = 0, next_uid=2) Apr 25 17:00:17 servera dovecot: IMAP(userd): /var/mail/Maildir/userd/dovecot-uidlist: Broken header (uidvalidity = 0, next_uid=8) I did already some mailinglist reviews. They confirmed in some way the problem, but there is still no explanation where it comes from, and how it can be solved or if it may affect the proper operation of the system. Here are some links with a short comment, which are related to this problem: http://www.dovecot.org/list/dovecot/2007-September/025541.html This post also uses nfs, but pam for authentication, error message is exactly the same as in our case. http://www.dovecot.org/list/dovecot/2007-July/024001.html Version upgrade from 1.0.0 to one above, also problems with uidvalidity. They described, that it happens only once for each user after upgrading. This is similar to our observations. No user complains as well ;). So it would be only of interest if it is so. http://wiki.dovecot.org/Clients/NegativeUIDs The number for uidvalidity is zero, so it is non-negative. But maybe it is correlated with these hints. From my point of view, there could be some problems with time synchronization as well between nfs server and dovecot server machine. But we checked this and they differ never more than 2 seconds. In total we are running two servers in parallel, each has it's own userspace, all accounts are strictly separated. One server is running the rc15 version, the other (more experimental) is running the backport 1.0.13. The described problem occurs only on the 1.0.13 server, which was previously updated. All other configurations are exaclty the same. Any hints? Best regards, Robert -- Dipl.-Inform.

[Dovecot] Quota not showing properly in webmail
by Eden 29 Apr '08

29 Apr '08

Hi I have a virtual users system using postfix / mysql / dovecot. Everything is working like a charm except for the quota display on webmail systems. It is working properly but showing GB instead of MB. For example. If I create a user with 100MB of quota and send him 50MB of mail, squirrelmail and roundcubemail display 50MB of 100GB If I create another user with 20MB quota and send him 10MB of mail, squirrelmail and roundcube dipslay 10MB of 20GB. if I send 50MB more I get the quota error msg I should get. So everything is workign but its displaying incorrectly. At first I though it was squirrelmail`s fault but it happens with roundcube as well, since both get their quota info from the imap server than I think its dovecot. I`m using Debian 4.0 This is the output of the --version and the -n dovecot commands. qgalvao-dns:/# dovecot --version 1.0.rc15 qgalvao-dns:/var/log# dovecot -n # /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3s pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_privileged_group: mail mail_location: maildir:/vmail/%n@%d maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: login plain digest-md5 cram-md5 user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail

[Dovecot] Connection problems using dovecot proxy
by Adrian Wojcicki | Unternehmensberatung Wojcicki 29 Apr '08

29 Apr '08

Hi Maybe somebody could help me with the following problem: I have set up a dovecot imap proxy in the dmz and a dovecot imap server in the intranet. Both in version 1.05. Now, while this setup works using Thunderbird, iPhone, etc. I have problems connecting using a Samsung Qbowl. It simply aborts with a connection error. Using the same setup but bypassing the proxy and connecting to the imap server directly does work for the phone. Logs on both servers don't show any errors. There is simply a "Info: IMAP(test): Connection closed" at the end. I enabled the rawlogs on the imap server but they don't long anything (They do log access from other imap clients but nothing from the phone). Could somebody point me into a direction where to look next?

[Dovecot] Imap sent folder sometimes dosen't get updated in dovecot-1.1-rc3(+some current hg patches)
by Diego Liziero 29 Apr '08

29 Apr '08

Yes, again, some sent emails don't get copied to sent folder. This time I get the following error: Error: IMAP(username): UIDs broken with partial sync in mbox file /maildir/username/Sent This happened at least with thunderbird and with evolution. Dovecot is running on vith fcntl locking on Centos5, sendmail should use fcntl, too. Filesystem is ext3 on drbd partition. After a grep vith dovecot.log I see the same error message also with other imap folders as well (mainly Trash imap folder). Should I try to get a rawlog? Regards, Diego.

[Dovecot] icedove update
by Karl Schmidt 29 Apr '08

29 Apr '08

Something came up that Confounded problems in my move from UW-imap to dovecot. I found a problem with the new icedove update in Debian lenny when moving from 1.5.0.13+1.5.0.14b.dfsg1-0etch1 to 2.0.0.9-3 that could look like a dovecot issue. Icedove runs for a while but eventually quits updating the displayed email, yet appears to be working and busy trying to get messages from the server. I think it is related to message filters, but not sure. The fix was to move .mozilla-thundrebird somewhere and restart icedove and create a new profile. There may be a more elegant fix. ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] sieve doesn't sift yet
by Colin Brace 28 Apr '08

28 Apr '08

Hi all, I am having difficulty getting sieve working. I created a simple set of rules which I've validated on the sieve-php page at SF. I placed this file, .dovecot.sieve, in the root of my maildir, which I understand is the default location. I also created a logfile in /var/log, but nothing has gotten written to it yet. Here is my configuration: $ sudo dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_location: maildir:/var/spool/vmail/%n mail_debug: yes pop3_uidl_format: %08Xu%08Xv auth default: verbose: yes passdb: driver: passwd-file args: /usr/local/etc/dovecot-passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/spool/vmail/%n What piece of the puzzle am I still missing?

[Dovecot] Public Namespace + ACLs + virtual users
by Fintec 28 Apr '08

28 Apr '08

g'day! I'd just like to share my experience with public namespace and ACLs. I know this has been discussed a number of times in the past, but there were no definite answers. dovecot version i'm using: 1.0.13 Got a public namespace setup in dovecot.conf as follows: namespace public { separator = . prefix = Public_Folders. location = maildir:/home/vmail/domains/% d/Public_Folders:CONTROL=/home/vmail/domains/%d/% n/Public_Folders/support:INDEX=/home/vmail/domains/%d/% n/Public_Folders/index hidden = no } In it's own right this works just fine and it's been in use for some time now. But we need some control over who can access and delete things. So I had a go at configuring ACLs. I configured global ACLs, because as far as I can tell, per directory ACLs seem to be ignored. Once configured global ACLs work fine, except for 1 major issue; users cannot create new folders because ACLs do not get propagated (are not applied to the subfolders). If an user attempts to create a new (sub)folder, the folder is created on the filesystem however email client throws an error and the folder is inaccessible to the user as there is no ACL for it. Any pointers how to get around this? Has this been dealt with in v1.1? Regards Natko Muzina

Hi Johannes. I wanted to try out the antispam plugin for a Dovecot 1.1 install, only to learn that 1.1 is actually not supported. Are there any plans to remedy this? If not, is it known how much effort is required? (i.e. could I do it myself?). Thanks, Anders.

[Dovecot] Does a script exist to fix broken maildir timestamps?
by drbob 26 Apr '08

Hello, When I upgraded to dovecot (changing servers at the same time) in November last year I copied the maildirs from my old server without using the -p option to preserve timestamps! Since my mail client displays the email dates based on the Date header rather than the imap "internaldate" I didn't notice the problem until today when I tried to migrate an account to gmail using imapsync and found that all emails prior to November display the wrong date in the web interface (they show the date they were copied in November). I feel very silly. Before I go try to hack together a script which parses all my older email files and changes the timestamps to the time recorded in the "Date:" header, does anyone know if robust, tested version of such a script is alrady available? Would correcting the timestamps in this way cause any problems for dovecot (e.g in the index files)? Thanks in advance for any help. drbob NB In my googling for a solution to this problem I found this hack to imapsync which would rewrite the "internaldate" based on the date header during a sync. Whilst I'd rather fix the timestamps that are the source of the problem, it may be useful for others finding this post in the future, see: http://www.zimbra.com/forums/installation/237-received-date-appears-incorre…

[Dovecot] Mixing LDAP and static
by Anders 25 Apr '08

25 Apr '08

I want to read quota size from LDAP, but I have a static value for home. How can I mix these? Right now, I have this LDAP configuration: user_attrs = uid=home=/var/mail/vhosts/%d/%n,gosaMailQuota=quota_rule=*:bytes=%$M which works fine, but looks up the uid attribute needlessly, and is not scalable: I have to pick a different, always-existing LDAP attribute for each static extra field that I want to set. Is there some LDAP configuration syntax like the SQL "SELECT '/var/...' AS home" ? Thanks, Anders.

[Dovecot] 1.0.5: many pop3-login processes?
by Alan Ferrency 25 Apr '08

25 Apr '08

Hello, We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range). We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes. Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running. Is this normal? Can we stop it? Is anyone else successfully running dovecot on FreeBSD 6.2? Thanks for your help.

[Dovecot] Problem with Dovecot Delivery Agent, Extra "From" lines and mbox
by Hokan 25 Apr '08

25 Apr '08

When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this. Example line, with ">" quote: >From hokan(a)hokan.org Thu Mar 8 17:28:01 2008 When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email. -- Hokan MEnet, a wholly owned subsidiary of Enet System Administrator Department of Mechanical Engineering hokan(a)me.umn.edu Institute of Technology 612.626.9800 University of Minnesota

[Dovecot] Authentication: Dovecot -> Vpopmail - > MySQL with one table per domain
by James Nordstrom 25 Apr '08

25 Apr '08

Hi All, I am using Dovecot 1.0.13 with Vpopmail (Qmail Toaster current) backed by MySQL with one table per domain (--disable-many-domains) . What I cannot figure out is how to have Dovecot authenticate to Vpopmail when Vpopmail uses one table per domain. Basically I need dynamic SQL in the Dovecot-sql.conf file. Currently I have: password_query = select pw_clear_passwd as password from domainname_com where pw_name = '%n' I need something like password_query = select pw_clear_passwd as password from %d where pw_name = '%n' Where %d is the name of the table. I can't use the exact domain name at it will not match the vpopmail format domainname_com. I would be happy to use some sort of sting builder but and not sure what my options are in the .conf file. Please help Thanks in advance James James Nordstrom Nordstrom Design Inc. E-mail: james(a)nordstromdesign.com US: 908-419-5597 Europe: 001/908-419-5597

Hi. I am unable to find information about what happens to the index file if I use something like the cron script at the bottom of http://wiki.dovecot.org/Plugins/Expire There must be some information in the index that is no longer needed. When and how will Dovecot clean this up? Thanks, Anders.

[Dovecot] sieve header :matches for multiline header
by Anton Yuzhaninov 25 Apr '08

25 Apr '08

RFC3028 say: Folding of long header lines (as described in [IMAIL] 3.4.8) is removed prior to interpretation of the data. The folding syntax (the CRLF that ends a line plus any leading whitespace at the beginning of the next line that indicates folding) are interpreted as if they were a single space. But it seems to be not true for dovecot-sieve-1.0.2 for header Received: from example.ru (example.ru [192.168.105.14]) by myserver (Postfix) with ESMTP id D4DA5D85927 This sieve test work: header :matches "Received" "from *by myserver (Postfix) with ESMTP id *" But this test not work, while should also work according to RFC: header :matches "Received" "from * by myserver (Postfix) with ESMTP id *" -- WBR, Anton Yuzhaninov

[Dovecot] ACLs generating plugin problems.
by "Fábio M. Catunda" 25 Apr '08

25 Apr '08

Hi! I'm trying to use an ACL to avoid deletion of messages that are inside .Trash folder, the ACL is already working very well, the problem that I'm facing is that even if the message is not deleted, mail_log logs that it has been deleted. Also, in some cases part of the lazy_expunge code is executed too, but sometimes I just dont know where the message is, thats weird. I erased deleted and expunged folders, then I deleted a message, It hasn't been deleted, but "deleted" and "expunged" folders has been created. Anyway, I would like to know if there is a way to stop plugin execution when an ACL matches. Thanks a lot.

[Dovecot] alert function, V2
by Stewart Dean 25 Apr '08

25 Apr '08

I guess the alert function is not part of the spec, because it appears to be unimplemented in Dovecot, even though most clients implement it. Timo, I would hope this would be easy to implement, and it's functionality that will be valuable to every installation. Here's why. America recently had the tragedy of a shooting rampage on a large university campus (yes, America should do something about the violence and free access to guns in our culture/society). What was worse was that, due to the lack of an emergency notification process, some 20+ people died needlessly. Now all college and university administration are scrambling to set up emergency notification processes. Our first take on this is a massive all-hands mailing list, but a) best case, it would take 15 minutes (and as much as an hour) to get to everybody's mailbox. b) users would have to read through their mail and stumble on the message What's needed is an "in-your-face" unavoidable alert, and the UWIMAP alert functionality provides this. As I recall, you touch just about anything in your IMAP client and there's a popup message in the middle of the client IMAP window...and it happens repeatedly. We tried it back 3-4 years ago and found it too annoying to use. For this purpose, it's perfect. The wy UWIMAP did it, the presence of the file /etc/imapd.alert triggers it, and the text in that file is transmitted to the client. The message has to be short, a one-liner for a small popup window, but this could be a pointer to a shared system message folder. Of course, DC could sense the activation of the alert in some other fashion that the presence of a file. Ideally, whatever activates the alert function should be able to be turned on remotely; I had in mind to do it using a mail aliases that is a pipe to a executable...

[Dovecot] Rare problem with Indexes?
by richs＠whidbey.net 25 Apr '08

25 Apr '08

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and issues a "SELECT INBOX", or "GETQUOTAROOT" when "maildirsize" needs rebuilding. When Dovecot hangs, no data is returned and no further commands are accepted, and the daemon must be killed. We see no errors in the logs, but have yet to catch the problem with "mail_debug" enabled. We're using NFS with Maildir's and these related options: mail_location = maildir:/mail/%Lu/Maildir:INDEX=/mail/%Lu/Cache mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_drop_priv_before_exec = yes mail_cache_min_mail_count = 128 mailbox_idle_check_interval = 5 maildir_stat_dirs = yes maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no Has anyone else run across the need to purge Indexes manually? Could this be unrecoverable Index corruption, or a locking issue? We've made a copy of the mailbox when the problem occurs. However, when we test it later, Dovecot re-builds the "dovecot.index" file itself just fine, and functions normally. We plan to "mail_debug" when this happens next to see if we can get more information. Thanks! -Rich

[Dovecot] Dovecot features
by Phan Thanh Diện 25 Apr '08

25 Apr '08

Hi, We would like to switch from courier-imap to dovecot. I have installed dovecot on a machine running FreeBSD 6.3 and now testing it. My questions are below: 1. Can I configure dovecot to delete all files that are older, say 10 days, from defined mail boxes (for example Trash or Spam). 2. After I access mail box (using web mail squirrel imap) all emails moved from 'new' directory to 'cur'. Then messages are not accessible for pop3. Such behavor doesn't occur with courier-imap. Can I force dovecot to behave like courier-imap? Many thanks for help. Dien Phan

I recently switched one of our 30 imap servers to 1.1RC4 from 1.0.x, and the difference is huge. The load on the server dropped from 5+ to 0.3 or so. This means there is no more io waiting going on. Thats on FreeBSD 6.2. Great work Timo! Cor

[Dovecot] dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor

Hello. Since I upgraded few months ago from version 1.0 to 1.1 (right now using v1.1.rc4) in logs for some users only (but in different servers) I noticed errors: dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor dovecot: Fatal: IMAP(user3): write(event_pipe) failed: Bad file descriptor So only for some imap users. And in different servers. And this error happens suddenly, I already tried to delete delete cache and index files. However the users themselves haven't noticed any problems.

[Dovecot] Sieve script executed, but nothing happens
by Wouter Amsterdam 24 Apr '08

24 Apr '08

Hi all, I think I have almost solved my dovecot-deliver lookup problems, but now sieve still fails to work.

[Dovecot] using mysql from within a plugin
by Alexander Prinsier 24 Apr '08

24 Apr '08

Hello, I'm trying to access a mysql database in a plugin. -What special compiler flags do I need? I discovered that when I don't explicitly link lib-sql/libsql.a in, then I get an undefind symbol error about sql_init when loading the plugin. Shouldn't the imap process itself have sql support linked in, rather than each plugin? -It appears that I need to call sql_drivers_init() and sql_drivers_register_all() before sql_init. Again, shouldn't the imap process do this, instead of each plugin? It should probably only be called once, so if one plugin already does it, then the second one will create problems. -When linking libsql.a in, and calling the functions mentioned above, then I get this error when starting dovecot: undefined symbol: mysql_ssl_set I'm guessing it's part of the mysql library itself, not dovecot. Can someone give me some hints on how to use dovecot's mysql library in a plugin? Thanks, Alexander

[Dovecot] Sharing Folders - or views?
by Nigel Allen 24 Apr '08

24 Apr '08

Hi All Running Dovecot v1.0.3 on FC 6. We have a Dovecot account which contains folders used by all staff. Think of the account as "Customers" and the folders as "Customer-1", "Customer-2", "Customer-3" and so on. We currently have around 650 of these customer folders. The problem is that there are currently 12 members of staff who need to see a subset of these folders (i.e. the customers that they are the manager for) but who also need to see (sometimes) the entire range of customer folders. Ideally what they would like to see is this kind of layout: +Personal Folders Inbox Trash Copies + My Customers Cust-1 Cust 7 Cust-25 Cust 33 + All Customers Cust-1 Cust-2 Cust-3 Cust-4 Cust-5 Cust-6 Cust-7 etc I suppose we could achieve this with symlinks but thought I would ask in case there is a "clever" way to achieve the same end. Thanks and Regards Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Windows Mobile and IMAP proxy
by Onno Molenkamp 24 Apr '08

24 Apr '08

Hi, We are running Dovecot proxies in front of our Dovecot IMAP servers, and were having problems with Windows Mobile clients not being able to connect. The clients would send a LOGIN command, and immediately after the succes reply a LOGOUT command. It turns out the Windows Mobile IMAP client gets confused by the IMAP proxy first sending the command tag in the reply and then, in a seperate packet, the rest of the line. Although not being able to handle this looks like a very bad design to me (how can one ever expect to read a full line in a single read() call?) I fixed it in our Dovecot proxies because we do have clients that want to use it. Attached is my fix for the problem. Onno

[Dovecot] Adding new storage backend to Dovecot
by Earl Dreller 24 Apr '08

24 Apr '08

I'm exploring adding a new storage backend to dovecot, storing mail in some sort of database, and had a few questions. Hoping someone here might be able to help :) -Is all of the 'storage' specific code in housed in lib-storage/index? Would adding a new storage backend be as simple as recreating all of the public functions of the current /mbox or /maildir code such as they pertain to that storage mechanism? -Where is the particular storage method controlled? I've had a look around but can't seem to find where the decision to use the 'mbox' or 'maildir' code is. -Finally, if there isn't a filesystem associated with the mail storage area, obviously the index data code will need to change somewhere. Any ideas on the complexities of that? Thanks!

[Dovecot] IMAP clients generate user home folders one level higher than needed
by andel 22 Apr '08

22 Apr '08

Hi (Of course not the clinets generate the folders, dovecot does, but I wanted to have the title not be too long.) I am using static userdb: userdb static { args = uid=vmail gid=mail home=/srv/vmail/%d/%n } and I have configured the hostname in protocol lda. Now when mail arrives for a known virtual user, the home directory with all subdirectories is being created correctly unter /srv/vmail/$domain/$vuser. But when connecting from an IMAP client (I have tested Thunderbird and Outlook) a new home directory with apparently correct subfolders is bring created unter /srv/vmail/$vuser ! The connection works, I just don't see the mails which arrived since the client is mapping a directory one level higher than needed. Where do I have to look for the cause? I did not find anything reasonable yet. Thank you in advance, David

[Dovecot] odd behaviour with antispam plugin
by ZyanKLee 22 Apr '08

22 Apr '08

hey, in my dspam database there has been some odd behaviour: during training dspam had created an uid entry named by the local part of the email. i.e.: user1 I use a virtual setup using dovecot, postfix and postfixadmin. On my first try I set up a database for dspam itself and there this happened. After I couldn't figure out how to solve this, I merged the database into the postfixadmin database. But using just the username for identifying email adresses is a bit critical within a virtual environment with multiple domains, isn't it? if one would not merge the databases - how could he solve this problem?

[Dovecot] Moving Maildir email messages and backing things up.
by Karl Schmidt 22 Apr '08

22 Apr '08

I just moved to dovecot with Maildir. I think this is probably a stupid question, but I couldn't find an answer after an hour of googling and searching the wiki. What would happen if I ran a script that did this: mv ~/Maildir/.folder_one/cur/* ~/Maildir/.folder_two/cur/ My hunch is it might break things. What if dovecot was stopped? ,.,.,. Where can I find a list of files in ~/Maildir/ and a note on what they are? (And similarly for a ~/Maildir/.folder) I'm wondering if everything needs to be backed up, or if I can/should skip the indexes. What happens if any of these files changes during the backup? (I'm thinking I shouldn't have to stop dovecot for a backup). ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] antispam plugin ehancement
by ML 22 Apr '08

22 Apr '08

I'm not a developper so I can't do it by myself, but I wonder if it could be possible to use tagSpam and tagNospam DSPAM feature to ehance user's dspam lerning experience. I even don't know if this must be done by DSPAM itself or by dovecot, but let me explain : The feature would be done by a signature replacement into tagSpam and tagNospam text, so the user would simply have to click on the link at end of the mail to learn DSPAM : # dspam.conf tagSpam on tagNonspam on # msgtag.spam If this message was classified SPAM by mistake, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} # msgtag.nonspam If this message should have been classified SPAM, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} I think a click is easier and faster than a forward, what do you think of such an implementation ?

[Dovecot] Feature Request - starting dovecot, config file behavior
by Charles Marcus 21 Apr '08

21 Apr '08

Hey Timo, I was wondering how much trouble it would be to again emulate the way postfix does something - in this case, the way it reads its config file when starting up. Current behavior: Postfix: If postfix encounters the same setting defined more than once, the last one wins. Dovecot: If dovecot encounters the same setting defined more than once it gives an error (also when using the 'dovecot -n' command). I like to add all of my changes to the very bottom of the config file, but otherwise leave the config file as is... this makes it very easy when updating - I can easily keep all of the new default config file, and simply merge my customizations at the end. So - how hard would it be to make dovecot simply accept the last defined setting read, instead of refusing to start? Thanks much, and glad to have you back in action! -- Best regards, Charles

[Dovecot] mailtrain with dovecot antispam plugin
by Hugo Monteiro 21 Apr '08

21 Apr '08

Hello all, and Johannes if you're around, I was trying to set up the "new" antispam plugin with the mailtrain backend, and i was trying to use the sendmail binary that's part of a qmail system. The message wouldn't get sent and i kept getting exit error 100 from the /var/qmail/bin/sendmail binary. To try to figure out what was happening, i mean a fake sendmail program, which is nothing more than a bash script to capture the command call input. The script is rather simple, it just places the calling parameters into a txt file and the stdin into another. code is #!/bin/bash echo $* > /tmp/sendmail-parms.txt exec cat<&0 >> /tmp/sendmail-msg.txt exit 0 So i tried a retrain and went to see what those txt files had. The parms.txt file was fine apparently, with cat /tmp/sendmail-parms.txt i got -f hm(a)hmonteiro.net notspam-hm(a)hmonteiro.net Then i did the same to the message file, with cat /tmp/sendmail-msg.txt, and i got the follwing Return-Path: <hugo.monteiro(a)fct.unl.pt>Delivered-To: hm(a)hmonteiro.net Received: (qmail 21616 invoked from network); 19 Apr 2008 16:21:17 -0000 Received: (simscan 1.4.1 ppid 21609 pid 21611 t 0.1451s) (scanners: regex: 1.4.1 attach: 1.4.1 clamav: 0.92.1 /m:46/d:6803); 19 Apr 0108 16:21:17 -0000 Received: from femme-fatal.resnet.costabasto.com (HELO femme-fatal) (192.168.0.20) by hmonteiro.net with SMTP; 19 Apr 2008 16:21:17 -0000 Subject: buy some viagra HURRAY X-DSPAM-Result: Innocent X-DSPAM-Processed: Sat Apr 19 17:21:17 2008 X-DSPAM-Confidence: 0.4945 X-DSPAM-Probability: 0.0330 X-DSPAM-Signature: 480a1bfd216125429498786 viagra sale really HURRAY cheap! only $5!

[Dovecot] building a simple antispam plugin
by Alexander Prinsier 21 Apr '08

21 Apr '08

Hello, I'm trying to build another antispam plugin, but some things are a bit unclear. In backend_handle_mail I put store the signature returned from signature_extract into my antispam_transaction_context. In backend_commit it appears that the signature is empty. (It wasn't in backend_handle_mail). Somehow between backend_handle_mail en backend_commit it has been cleared... When I use i_strdup it appears to work. Anyone can tell me where this clearing happens? Is i_strdup the right way to do it then? Thanks, Alexander

[Dovecot] How to deal with mail to unknown virtual recipients?
by Andreas Ntaflos 19 Apr '08

19 Apr '08

Hello list, I am not quite sure whether this is a questions for Dovecot or Postfix. I have set up, virtual hosting for one domain (for test purposes) using a passwd-file as passdb and a static userdb (see dovecot -n at the end) along with Postfix in a manner described in [1], i.e. a non-Postfix mail store. Other than that I also do hosting for the canonical domain which is for users with a regular Unix account on the system (looked up via PAM) The virtual domain shall be "example.org", with two users "alice(a)example.org" and "bob(a)example.org". But today I received spam mail (which was correctly identified as such by amavisd-new) for "info(a)example.org" and "sales(a)example.org", two recipient addresses that do not exist. According to [1] "it's left up to the non-Postfix delivery agent to reject non-existent recipients from local submission or from local alias expansion." How to deal with such a situation? The sender address was clearly forged so returning a failed delivery message is pointless. The messages are now hanging around in the queue with a status of "deferred: temporary failure". The logs show: dovecot: auth(default): passwd(info(a)exmaple.org): unknown user dovecot: auth(default): passwd-file(info(a)mexample.org): unknown user dovecot: auth(default): static(info(a)example.org): passdb doesn't support lookups, can't verify user's existence postfix/pipe[25328]: C7EA18BC0B5: to=<info(a)exmaple.org>, relay=dovecot, delay=1.4, delays=0.07/0.02/0/1.3, dsn=4.3.0, status=deferred (temporary failure) The dovecot relay is defined in /etc/postfix/master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} The question, once again, is: what to do in such a situation? A catch-all address could be set up, but to what end? It would just catch a lot of spam over time. What is the correct way to deal with this? More importantly: is there even anything Dovecot could (or should) do?

[Dovecot] Delete antispam emails
by David Reid 19 Apr '08

19 Apr '08

I'm using dovecot with the antispam plugin to allow for training, but how do I delete emails once they've been trained? If I delete them from the folder using an email client they get retrained as valid emails when they're moved to the trash folder! D'oh. I'm looking, ideally, for a solution that doesn't need a script to be run per user as I have a number of users using this feature. Also, the cleanspam script doesn't seem to be able to find the folder I'm using ('SpamTrain') so what format should I use? Thanks. david

[Dovecot] CRAM-MD5 HMAC-MD5 password algorithm for PHP
by Hajo Noerenberg 18 Apr '08

18 Apr '08

Hi, based on the recent discussion by Bill Cole and Douglas Willcocks I've quickly put together a PHP script which generates MD5 'contexts' for Dovecot's password files: http://www.noerenberg.de/hajo/pub/dovecot_hmacmd5.php.txt The script has not been tested extensively, so use it on your own risk :) Most of the code has been shamelessly stolen from various sources. You'll find the names in the header of the script. Hajo

[Dovecot] Message UID Question
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 18 Apr '08

18 Apr '08

I have referred to the wiki and the RFC, but I still can't find the exact answer I'm looking for. From what I know, Dovecot uses the IMAP standard of 32 bit integers to uniquely identify messages. After a message is deleted from the mbox, can this UID ever be reissued to a new message or is that UID retired? What about after the 2 billion limit is reached? Thanks!

[Dovecot] Please help: LDAP configuration _almost_ works.
by Jack McKinney 18 Apr '08

18 Apr '08

Red Hat Linux release 7.2 (Enigma) OpenLDAP 2.3.38 Dovecot 1.0.12 SHORT VERSION ----- ------- Here is my dovecot-ldap.conf: hosts = ldap.lrtz dn = cn=varmail,ou=users,dc=lorentz,dc=com dnpass = ********* ldap_version = 3 auth_bind = yes pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu)) base = ou=users, dc=%Dd scope = onelevel I have tested using the above information with ldapsearch, and it works fine. However, when dovecot tries to authenticate the user, the LDAP server receives the query and responds to it (according to the LDAP log file), but dovecot just hangs there. 180 seconds later, it drops the IMAP client. E.g.: The dovecot log shows: Apr 3 08:13:21 fourier dovecot: auth(default): new auth connection: pid=15774 Apr 3 08:13:30 fourier dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=x.x.x.x^Irip=y.y.y.y^Iresp=<hidden> Apr 3 08:13:30 fourier dovecot: auth(default): ldap(jackmc(a)lorentz.com,y.y.y.y): bind search: base=ou=users, dc=lorentz,dc=com filter=(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) Apr 3 08:16:30 fourier dovecot: imap-login: Disconnected: Inactivity: method=PLAIN, rip=y.y.y.y, lip=x.x.x.x, TLS The OpenLDAP log shows that the query is received and that it returns a match: Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH base="ou=users,dc=lorentz,dc=com" scope=1 deref=0 filter="(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))" Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH attr=uid Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SEARCH RESULT tag=101 err=0 nentries=1 text= LONG VERSION ---- ------- My users login using their email address as username. Each domain has their own LDAP subtree. Each user has an entry in the ou=users subtree of the domain subtree, and has a mail: field (inetOrgPerson) listing their email address/login name. I am trying to use auth_bind: when I login with jackmc(a)lorentz.com, dovecot should search for mail=jackmc(a)lorentz.com in the onelevel below ou=users,dc=lorentz,dc=com and find me as "cn=Jack McKinney,ou=users,dc=lorentz,dc=com". I have created an entry in LDAP (varmail) that should be able to do this query. Indeed, from the command line, it works: ldapsearch -h ldap.lrtz -b 'ou=users, dc=lorentz, dc=com' -D 'cn=varmail,ou=users,dc=lorentz,dc=com' -x -W -s onelevel '(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))' Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=users, dc=lorentz, dc=com> with scope oneLevel # filter: (&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) # requesting: ALL # # Jack McKinney, users, lorentz.com dn: cn=Jack McKinney,ou=users,dc=lorentz,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson cn: Jack McKinney givenName: Jack McKinney sn: McKinney mail: jackmc(a)lorentz.com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 It appears that dovecot performs the above query successfully, but then never uses the password and retrieved DN to attempt to bind and authenticate the user. Instead, it just times out. (See log files above in the SHORT VERSION). I tried to add pass_attrs, in case there was a bug in dovecot where it ignores the reply if there are no pass_attrs (even though none are needed), but it still fails the same way. Timo Sirainen suggested that I add a debug line to src/auth/db-ldap.c ldap_input() around line 372: msgid = ldap_msgid(res); // added line: i_info("LDAP: Received reply %d", msgid); I did this. Now, when the server first starts up, this line is logged. However, it is not logged when it queries the LDAP server as a result of an IMAP connection needing authentication. -- Jack McKinney GPG 1024D/99C6A174 jackmc(a)lorentz.com YM:lfaatsnat2006 AIM:jackmclorentz "There is no parameter that makes it impossible for you to perform still more excellently." -Mario Cuomo, on the lack of a clock in baseball

[Dovecot] Dovecot LDA / Deliver question
by Stacy Trippe 18 Apr '08

18 Apr '08

Problem described: I am trying to get Postfix + Dovecot + MySQL setup to work together in a virtual mail hosting platform. I am running Postfix 2.3.x, and MySQL 5.0.x. I am trying to use Dovecot's LDA for delivery to the users vmail home directory -- usually under /var/vmail/domain.com/j/jdoe for home and /var/vmail/domain.com/j/jdoe/.maildir for mail location, using MAILDIR format. However, I cannot get Dovecot's LDA to write the maildir folders/files into the right location. It wants to write in MBOX format to /var/vmail/mail/inbox instead. When I force the mail_location variable...it just uses the system 'vmail' user (uid: 1101) and 'vmail' group (gid: 1101) that I assigned for the virtual mail user. mail_location = maildir:/var/vmail/%d/%1n/%n I am not sure where to go to troubleshoot Dovecot LDA...and how to turn up/down the verbosity of debug messages (albeit now I am logging the deliver info to /var/log/dovecot-deliver.log). Does anyone know what I am missing? Can Dovecot LDA be told how to deliver mail to the users maildir folder? Here is my postfix master.cf: ... dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/libexec/dovecot/deliver -f ${sender} Here is my postfix main.cf (as it pertains to dovecot LDA): virtual_transport = dovecot mailbox_command = /usr/libexec/dovecot/deliver smtpd_sasl_type = dovecot dovecot_destination_recipient_limit = 1 dovecot --version 1.0.rc15 dovecot -n # /etc/dovecot.conf log_path: /var/log/dovecot.log login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: SMTP ready. login_process_size: 64 login_processes_count: 5 login_max_connections: 512 mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: passwd userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=mailsql user=mailquery password=m@1l default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, passwd AS password, concat('/var/vmail',homeDir) as userdb_home, 1101 AS userdb_uid, 1101 AS userdb_gid, concat('maildir:/var/vmail',mailDir) as userdb_mail FROM users WHERE (username = '%u' OR email = '%u' OR email = concat('%u','@domain.net')) AND status = 'A' AND type = 'M' user_query = SELECT concat('/var/vmail',homeDir) as home, 1101 AS uid, 1101 AS gid, concat('maildir:/var/vmail',mailDir) as mail FROM users WHERE username = '%u' ....

[Dovecot] Feature request
by Ruud Boon 18 Apr '08

18 Apr '08

Hi! I hope I'm using the right mailing for a feature request. I'm using dovecot on my server for a year now and I'm very happy with it. Its extremely stable and fast. Ok what is my situation why I'm asking a feature.. Users are retrieving mail using pop3 over the external ip address. When the user connects to there webmail. The webmail client (Squirrelmail) is using imap on the localhost. I would like to give some users the option to use imap over the external ip, I want to set option in my MySql backend configuration. As far as I know there isn't a possible solution on dovecot right now that's why I hope you can build a extra config parameter that gives me the possibility to allow users to retrieve email by imap by ip. So all users can do an imap request on localhost (for webmail) and some user are allowed to do an imap request over the external ip. I hope that my request is clear and I'm posting in the right group. With regards, Ruud Boon

[Dovecot] Single quote email addresses
by Guy 18 Apr '08

18 Apr '08

Hi, I've just been told that I need to make our mail server cater to accounts with single quotes. Has anyone set dovecot up to do this or know of any documentation/howto on it, assuming it's possible at all. I'm running dovecot 1.0.5 on Ubuntu 7.10 if that makes much of a difference. Thanks for any help anyone can give. Guy -- Don't just do something...sit there!

[Dovecot] dovecot + qmail - deliver not working...

Hi List, I have a working qmail server and installed dovecot trying to setup vmail... it's not going as expected...

[Dovecot] dovecot and postfix virtual mailbox domains, system users
by Dave 18 Apr '08

18 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username/, there's a maildir under that area and incoming mail gets delivered by postfix to that area. In the first case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account at all. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd and the specific maillog error is this: Apr 11 23:48:17 s15298471 dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=66.139.186.37, lip=74.208.64.129, TLS Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): Couldn't open INBOX: Internal error occurred.

[Dovecot] remove mails from shared folders
by Patrick Fischer 18 Apr '08

18 Apr '08

Hallo dovecot This is my first post on this list. I'm new to IMAP servers and i read lots of howtos. If I use the wrong term for some features please tell me the right term. I have installed dovecot under ubuntu 7.10 and it works fine. dovecot + fetchmail + postfix I would like to use shared folders the way that we have an email pool for info(a)mydomain.com user1(a)mydomain.com -> User1 user2(a)mydomain.com -> User2 user3(a)mydomain.com -> User3 info(a)mydomain.com -> Pool (look at this http://decembersoul.dyndns.org/wiki/images/c/c6/IMAP1.jpeg ) The users can see and process emails from the email pool. To process an email the user move the email from the email pool to his own inbox. This should make sure that only one user process a email. Shared folders are created by symlink. The problem is that, if a user move an email out of the email pool, the other users still can see the mail in the pool. It takes a long time to remove the mail from the pool for every user. Move TO the pool works immediatley. The user can make a "compress folder" to remove the emails but this can't be the soulution. Maybe this is a client failed (tested only with thunderbird) Best regards Patrick Fischer

[Dovecot] Minor namespace issue - inconsistent default value
by Joel Johnson 18 Apr '08

18 Apr '08

I burned some time yesterday over a documentation inconsistency. The dovecot-example.conf file shipped with dovecot (checked with 1.1rc4 and the April 3 nightly), includes an indication at the top that the commented values listed are the defaults for the settings. Line 248 of this file has the inbox setting for a private namespace which indicates that the default value for this setting is true. However, line 358 of ./srv/master/master-settings.c sets the default value of the namespace inbox variable to false. With a single private namespace (what I was setting up), one wants this value to be true, however when using multiple namespaces the default should likely remain false. I propose keeping the coded default and changing the line in the example configuration file to indicate false. Before I determined that this was the issue, I had a single namespace defined (but not as INBOX), and dovecot (both deliver and imap) created and read from a .INBOX directory under the Maildir. Thanks, Joel

If I have two databases in my ldap, ex: dc=dominio1,dc=it is the first database and dc=dominio2,dc=it is the second one. Can I put these two search bases in dovecot-ldap.conf?

[Dovecot] Bah! Outlook
by Jason Wohlford 18 Apr '08

18 Apr '08

Hi All, I run a little hosting company. I use Dovecot 1.0.10* with IMAP exclusively. Lots of my customers use Outlook or Outlook Express. This poses a problem. These programs don't and have absolutely no workarounds to move messages to a trash folder when deleted. They only mark the message for deletion. Then, users have to purge the message to actually delete it. Outlook has a way to hide deleted messages and also auto-purge them when moving to a different folder. That just doesn't cut it. (Thanks Microsoft! :-p ) So, I'm thinking Dovecot could pick up where Microsoft left off. It seems to me there needs to be two things done. First, a system that automatically copy a message marked for deletion from one folder (e.g. INBOX) to a trash folder (e.g. Trash, Deleted Messages, etc.) Dovecot's lazy_expunge might already do this, but I couldn't quite discern it from the wiki docs. Second, a way to only do this when Outlook or Outlook Express is the one who is deleting a message. Possibility? Comments? Cheers, Jason P.S. Thanks for the great software! *Yes, I know. I need to upgrade to Dovecot 1.0.13. -- Jason Wohlford <jason(a)wohlford.org> <http://wohlford.org>

[Dovecot] keep users from deleting email
by Adam Williams 17 Apr '08

17 Apr '08

I looked on the dovecot website, but didn't find an answer. With dovecot 1.0, is there a way to keep users from deleting their email? So that when they click the delete button on their email client, nothing happens/dovecot refuses to delete email, etc?

[Dovecot] Dovecot 1.1rc3 "Out of Memory" crashes from pop3-login?

[Dovecot] CRAM-MD5 Password Generation Algorithm
by Douglas Willcocks 17 Apr '08

17 Apr '08

Hi, I'm just in the middle of setting up dovecot to serve IMAPS -- Actually I've finished apart from one thing: CRAM-MD5 passwords. I'm using SQL as a backend for the password storage, and I don't want to store the passwords in plaintext. I've also configured dovecot to be rather restrictive when it comes to authentication methods (only CRAM-MD5 is allowed). To generate the passwords to go into the database I can use the dovecotpw utility, but I'm wanting to stick some sort of minimal admin interface on the server to be able to manage the users etc without having to use the CLI. I've looked at the theoretical explanation of the hashing algorithm, and I've read through the source code that dovecotpw uses to generate the passwords with the intent of creating a higher level language library (Perl, Ruby, PHP ... whatever)) to generate passwords, but I don't seem to be able to replicate the functionality, and there don't seem to be any existing libraries that generate consistent results (that I've found). I don't have that much experience with C, and so I'm sure that I must have misunderstood how dovecotpw does its stuff. Perhaps someone could explain how the algorithm works? Or point me in the right direction? Thanks, Douglas Willcocks

[Dovecot] Dovecot-deliver lookup fails
by Wouter Amsterdam 17 Apr '08

17 Apr '08

Hi all, I'm still trying to get Dovecot-deliver to work in my config. I have found the problem to be in the maildir lookup for Dovecot-deliver as logged in /var/log/maillog: "Apr 15 16:30:34 termserv dovecot: auth(default): static(user(a)zesgoes.nl): passdb doesn't support lookups, can't verify user's existence" The thing I don't get, is that if I remove the virtual_transport modifications in /etc/postfix/master.cf and /etc/postfix/main.cf and the socket listen in /etc/dovecot.conf, all works well. So dovecot has no problems looking up my users on a LDAP server as a passdb backend, but failes when using the same passdb for dovecot-deliver. How come? TIA, Wouter
