[Dovecot] Panic: IMAP(...): Trying to close mailbox INBOX with open transactions
by Mike Abbott 16 May '08

I have been seeing this crash, which has been reported before but apparently not yet resolved. As with the previous reporters, I do not know how to reproduce it reliably. Dovecot version: 1.1.rc5 Operating system: Mac OS X 10.5.2 CPU architecture: x86 File system: HFS+ Activity: From the backtrace it appears the client logged out while in the middle of some operation.

[Dovecot] Sieve plugins 1.0.3 and 1.1.5 released
by Timo Sirainen 16 May '08

http://dovecot.org/releases/sieve/dovecot-sieve-1.0.3.tar.gz http://dovecot.org/releases/sieve/dovecot-sieve-1.0.3.tar.gz.sig http://dovecot.org/releases/sieve/dovecot-sieve-1.1.5.tar.gz http://dovecot.org/releases/sieve/dovecot-sieve-1.1.5.tar.gz.sig I've usually released new Sieve plugins at the same time as new Dovecot versions, but since I wasn't planning on releasing v1.0.14 anytime soon and it looks like v1.0.2 release was quite a while ago, I decided to release these today. 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.

[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.

[Dovecot] Disconnected: BUG internal error

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.

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.
