[Dovecot] Duplicate suppression from remote lists?
by Adam Seering 12 Dec '08

12 Dec '08

Hi, I have a setup where users on my server who are subscribed to several lists on a (remote) weirdly-configured listserver are getting many duplicate e-mails. I know why this is happening; but I don't have control over that listserver so I can't fix it. Is there a way for me to suppress duplicates from within Dovecot? The duplicates do all have the same (otherwise-unique) message ID. "dovecot --version" gives 1.0.rc15. I'm using exim for SMTP. I'm also using dovecot-lda, with the Sieve plugin. There's a rather old thread on this list that mentions that dovecot-lda+Sieve should be able to suppress duplicates; it's not doing so automagically, though... Thanks, Adam

[Dovecot] W= fixup feature
by Arkadiusz Miskiewicz 12 Dec '08

12 Dec '08

Hi, When there are maildir mail files without W= tag in name then dovecot opens them, read data inside to calculate W= size, cache that information etc. Would be it sensible to have option where dovecot would fix names of such files? Like if no W= then after calculating size rename file to actually contain W= ? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Do not update status on imap connections
by Adrian Reber 12 Dec '08

12 Dec '08

Does an option like "pop3_no_flag_updates = yes" also exist for imap? Is it maybe planned? Or should I just provide a patch? Adrian

[Dovecot] dovecot howto?
by Olaf Zaplinski 11 Dec '08

11 Dec '08

Hi, is there a *simple* HOWTO that explains a simple postfix+dovecot setup? Up to now, I used postfix+cyrus, worked fine. But I do not get postfix+dovecot to work. Currently, all emails go to /dev/null. What really would help me is a dovecot lmtp server. Is there any? Regards Olaf postfix main.cf: # -- delivery options # local_recipient_maps = virtual_alias_maps = btree:/etc/postfix/virtual alias_maps = btree:/etc/postfix/aliases alias_database = btree:/etc/postfix/aliases # mailbox_command = /usr/lib/dovecot/deliver mailbox_transport = dovecot postfix master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} dovecot.conf: mail_location = maildir:/home/vmail/%u namespace private { separator = '/' inbox = yes } auth default { mechanisms = cram-md5 plain verbose = yes passdb passwd-file { args = /etc/dovecot/passwd } userdb static { args = uid=vmail gid=vmail home=/home/vmail/%u } socket listen { client { # Assuming the default Postfix $queue_directory setting path = /var/spool/postfix/private/auth mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix } } }

[Dovecot] removal of all keyword.
by Matthias Rieber 11 Dec '08

11 Dec '08

Hi, how can I remove all keywords from an existing Maildir/? After reading the docs I assume this might work: 1. Stopping dovecot 2. Removing all lowercase [a-z] from the filename flags 3. Removing the dovecot-keywords file 4. Removing the dovecot.index / dovecot.index.* files Is that correct? matthias

Yes, but when Dovecot is spawned as service, the user dovecot does not log in (through PAM anyway to have pam_limits invoked), therefore I assume that limits.conf does not take effect. > Dovecot ran with a lot of proccess here, something about 800~900 imap > proccess and 5~10 login-proccess to 300~400 simultaneous users...

[Dovecot] Mixing MBOX and MAILDIR
by Romer Ventura 08 Dec '08

08 Dec '08

Hello, I have about 100 mboxes, a few with a lot of mails and others with a few mails. I have configured dovecot to use maildir as mail format, but I would like to give users the ability to access their old email located in their old mbox. So all the new mail would be in the ~/Maildir/ and their old or archived email in /home/vmail/mboxmail/%Ln How can I add a namespace to achieve my goal...? namespace private { separator = / hidden = yes prefix = "#mbox/" location = mbox:/home/vmail/mboxmail/%Ln/ } Like that...? Thanks for any inputs...

[Dovecot] LDA questions
by Romer Ventura 08 Dec '08

08 Dec '08

Hello, I am looking at the docs and I see this: Problems with deliver Namespaces are supported with v1.1 and later. With v1.0 and older versions mails can be delivered only to mailboxes specified by the mail_location setting. But in the dovecot.conf I see: # NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently ignore # namespaces completely, they use only the mail_location setting. I am running 1.1.7 so is that a typo in the dovecot.conf or the wiki page..? Also, I got postfix+dovecot configure to authenticate to Active Directory using pam_krb5 and I am able to login and send emails with pop3 or imap, but unable to receive emails since postfix complaints about the user not being found in the local recipient table. Now I have made a few changes, but I cant get to see deliver complaint, all I see is: postfix/smtpd[19924]: NOQUEUE: reject: RCPT from ............: 550 5.1.1 <test1(a)domain.com>: Recipient address rejected: User unknown in local recipient table; So I think that it is not being passed to deliver... Master.cf has: dovecot unix - n n - - pipe flags=DR user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} Main.cf has: virtual_mailbox_domains = your.domain.here virtual_transport = dovecot Any ideas..?

[Dovecot] Just some user input
by Brandon Lamb 08 Dec '08

08 Dec '08

Hi Timo, You may remember some of my mails, I was having unusual high load issues using pop3 with dovecot over nfs, and unusual being the load on anywhere from 1 to 4 servers would run at 2 to 4 for a week then all of a sudden would spike to 60 and higher (saw 150 once). I have been banging my head on the wall for the last 1.5 to 2 months since switching from courier to dovecot, the imap has worked great but the pop3 was a problem out the door. Anyway, I finally tried loading dovecot directly on our raid, all loads across the board dropped to the floor. The single P4 3ghz purrs along at an easy 0.30 load where the 1 to 4 quad core boxes with brand new hardware were loading up to 60 when using nfs. So, my experience has been that maildir, nfs and dovecot as the pop3 server was unusable. I wasnt really sure this whole time, it seemed odd that a single P4 box using nfs and courier pop3 could handle the entire system load but dovecot with the same and more quad cores fell over was weird. Anyway, this is totally not meant as a bashing or anything, just information. Im not a C programmer so I really cant offer anything but my input/observations. Maybe the pop3 part of dovecot isnt really given much love or people are mostly just interested in the imap server? Or maybe most people dont use nfs? Totally just assumptions here. A definite positive here though, after moving dovecot directly to the raid server, wow, our mail TOTALLY hauls ass now. Two of our managers both noticed the huge speed increase. One of them uses pop3 and leave messages on server and has almost 4,000 messages in the inbox on the server, his webmail now loads literally instantly, i click login and count 1 second. That is amazingly fast. I dont have any hard numbers, but before our upgrades his "feeling" was that he seems to remember it taking up to 30 seconds for webmail to load his mailbox. that is an incredible difference. Our webmail uses imap by the way, so this is probably a combination of moving from nfs and switching from courier to dovecot. Ok thanks for your great hard work and sorry for the novel size post.

[Dovecot] catching authentication failures with LDAP backend
by Udo Rader 06 Dec '08

06 Dec '08

Hi, we have recently been hit by a couple of brute force password attacks against dovecot. So what I want to do now is to add dovecot to fail2ban in order to block further attacks. However, I don't seem to be able to find out password verifification failures for our LDAP based user data. The only thing I see are loads of lines like these in the logfiles: -------CUT------- dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<ludovic>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<luna>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<luke>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 -------CUT------- Googling the web I found that PAM based authentication obviously gives a matchable error message, but for some reasons the ldap backend does not - or does it? Any pointers highly appreciated :-) dovecot -n says this: -------CUT------- # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imaps imap pop3 listen: 81.16.98.99 ssl_listen(default): 81.16.98.99 ssl_listen(imap): 81.16.98.99 ssl_listen(pop3): ssl_cert_file: /etc/bestsolution/ssl/mail.bestsolution.at-cert.pem ssl_key_file: /etc/bestsolution/ssl/mail.bestsolution.at-key.pem ssl_parameters_regenerate: 24 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: 9 mail_access_groups: mail mail_privileged_group: mail default_mail_env: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:~/mail/:INBOX=/var/mail/%u mmap_disable: yes lock_method: dotlock 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_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): %v.%u auth default: mechanisms: plain digest-md5 cram-md5 login passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix -------CUT------- -- Udo Rader, CTO http://www.bestsolution.at

I have an unsigned SSL certificate with Dovecot and connect fine using OSX.5's Mail.app. What do you mean, "unable to connect"? Do you really mean "unable to connect", or do you mean, "an error message comes up every time they try to connect"? If its the latter complaint, please see this document: http://support.apple.com/kb/TA22383 I know it says 10.3 Mail, but the steps to follow are essentially unchanged between 10.3 and 10.5.

[Dovecot] quota warning for fs quota
by Florian Effenberger 05 Dec '08

05 Dec '08

Hello, I configured my Dovecot to use filesystem (fs) quota. It works fine, the correct free/used space and percentage is being shown to the client. However, the warning feature doesn't seem to work, no mail is being sent, although executing the script standalone works fine. Is quota warning for fs quota supported? I use Dovecot 1.0.10 (Ubuntu package). Thanks, Florian

[Dovecot] Auth_username_format question
by Romer Ventura 05 Dec '08

05 Dec '08

Hello again, I have change authentication to LDAP from Kerberos due to recent changes to my plans and I am having a little problem getting the malbox created in desired path. At the moment the home folders are being created in: /home/vmail/DOMAIN.COM/%Ln and it worked great with kerberos, but with LDAP the domain part is missing so I did the following: Auth_username_format = %Ln Then I did: # telnet localhost pop3 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user test4(a)domain.com +OK pass password +OK Logged in. But I saw in the logs the following: dovecot: auth(default): master out: USER 1 test4 uid=1001 gid=1000 home=/home/vmail//test4 The domain was missing.. So does it mean that auth_username_format dictates what dovecot will use, not only for the authentication part, but for everything else as well..? To me it seems that once the username has been formatted it forgets everything that doesn¹t constitute part of the specified format. Or am I misunderstanding the entire concept..? How cant I preserve the domain part so that the homes can be placed in the desired location: /home/vmail/%d/%u...? Thanks

[Dovecot] Dovecot Proxy with MySQL auth
by Justin Krejci 04 Dec '08

04 Dec '08

We are looking at deploying several pop/imap servers to house the mail for 15,000 or more mailbox accounts. We are contemplating on the design and are looking at using MySQL auth (we already have a MySQL environment in place for our user auth to live) and proxy_maybe so each server can proxy for all the others and we just have a network load balancer distribute the incoming connections to all of the Dovecot servers. Each server would have its own local maildir storage for the users local to that server and all of the authentication and target backend pop/imap server data would be stored in the same MySQL database. The problem we are running into is the documentation is not very clear on this type of scenario. http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy At the bottom of this page it gives a query example of "SELECT NULL AS password, ." but that does not seem to allow for us to use the proxy_maybe if the destination server is localhost (and therefore do not proxy) it does not seem that the above query will actually send the real password for authentication. Is this a misunderstanding on our part or is the use of mysql auth + proxy_maybe not feasible? Assuming the latter we surmised using a separate instance of Dovecot on each machine to act solely as a proxy front end (use proxy instead of proxy_maybe) then on the second instance there is no proxy config and it listens on a separate TCP port like 80143 or whatever. Any input or suggestions would be appreciated. Justin Krejci

I've been running 1.2alpha3 for weeks now without issue. However, some people in my testing department object to even testing "alpha" code. Are there specific features/bugs that need resolved before alpha reaches beta? Thanks, Jonathan

[Dovecot] Dovecot authenticating to multiple kerberos realms
by Romer Ventura 04 Dec '08

04 Dec '08

Hello, I got Postfix, Dovecot 1.1.7 configure to use pam and the pam.d/dovecot file is configure to use pam_krb5 module. Everything is working with no problems, but I am finding that the user must type the domain part in uppercase in order to successfully authenticate. So I am wondering if there is any way for the user to login as user1(a)domain.com instead of user1@DOMAIN.COM...? Any ideas..? Thanks

[Dovecot] Antispam plugin + scriptsieve
by Allan Cassaro 03 Dec '08

03 Dec '08

Hi, I wrote a little python program that works with antispam plugin, to create or remove sieve rules based on "From:" of any e-mail that is moved to some folder configured in dovecot.conf. He works fine with "Felamimail" the email program of "eGroupware". After setup, is very simple: If an user move a message to "blocked" folder, is appended a rule in the script sieve of this user. If the message is deleted or moved out that folder, the rule is removed too. The setup is very simple: (after setup antispam plugin) Change this in dovecot.conf: protocol imap { mail_plugins = antispam } plugin { antispam_spam = Blocked antispam_mail_sendmail = /usr/libexec/dovecot/blockthis.py antispam_mail_sendmail_args = -u;%u antispam_mail_spam = -a antispam_mail_notspam = -d } Hooo... this script create a "include global script" statament in script sieve... If you don't want this feature, just comment this 2 lines: sievelist.append('require ["fileinto", "include"];\n') sievelist.append('include :global "global.sieve";\n') Here this is very useful! :D This script was created to suit my needs, so, have some paths in the code... It's not very "user friendly" yet... but if have intereting I will implement others features (like a config file). Download here: http://allan.cassaro.googlepages.com/blockthis.py Regards.

[Dovecot] my_vsnprintf crash on HP-UX

Hi, sorry for the double post, I stupidly composed this as a reply to an earlier mail, which causes it to appear in an older thread.

by Roald Amundsen 03 Dec '08

03 Dec '08

Hi! I have a server with a few thousand mailboxes (for a few hundred domains) on it. The usernames are following several naming conventions: username_domain domain_username username_domain.tld username-domain domain.username The reason for this chaos is that the accounts were set up on different mailservers, some imail, some linux, some with virtualmin and some manually and through aquisitons etc it has all ended up in one server. Now we are setting up atmail to replace imp. The loginprocess of atmail is a bit different in that you just type in your mail address and atmail tries a few combinations of loginnames to login. However, some of the combinations over atmail cant login to. Some of them works fine when using this line in dovecot.conf auth_username_translation = @_ Is there any facility to let dovecot do username mapping? If I eg have a file: usermapping that looks like this: user(a)domain1.com domain1_user user(a)domain2.com user_domain2 user(a)domain3.com domain3.user And yes, I know that the best way is to start again and use virtual domains and get all into one naming standard, but unfortunately, that is not going to happen. The other alternative is of course to hack into the source code of atmail, but I am not that confident in PHP. Any ideas? -- Regards Roald Amundsen

[Dovecot] Problem with sieve: Keep: Generic Error
by Thomas Siebert 03 Dec '08

03 Dec '08

Hi, i came across a strange error message in Ubuntu 8.10s package (Dovecot 1.1.4) regarding sieve: sieve runtime error: Keep: Generic Error sieve_execute_bytecode(/etc/dovecot/sieve/default.sievec) failed Note that the Sieve Scripts are basically executed fine and working fine. After a lot of testing I suppose the following: "keep" doesn't detect the private namespace I have to use (courier-compatibility...), thus sieve fails to do "keep", the message is handed back to dovecot-deliver which does a "keep"-similar action itself. If I have a script with "keep;" as the only command, I get this error message. If my script is totally blank (i.e. implicit keep only), I get the same error. But if there's no implicit or explicit "keep", e.g. "fileinto INBOX;" as only command, there's no error. Also IMAP-Folders, e.g. "fileinto INBOX.Test", work. Unfortunately, "fileinto INBOX" as default is no option for me, as I use a delimiter and want to let deliver put the mails into the according IMAP-Folders. Is this a known bug? Any Ideas?

[Dovecot] Compilation of 1.1.6 fails on HP-UX 11.31
by Marc Beyer 02 Dec '08

02 Dec '08

Hi, $ uname -srv HP-UX B.11.31 U $ cc --version cc: HP C/aC++ B3910B A.06.20 [May 13 2008] Compilation fails, output of configure and make are given below. The cause of this is almost certainly that this version of HP-UX does define the QCMD macro in sys/quota.h (checked in the ifdef line 26 dovecot-1.1.6/src/plugins/quota/quota-fs.h) as well as the dqblk struct, but the latter with different fields than the Linux version. Older versions of HP-UX seem not to have contained this macro(? can't check this at the moment), which is probably why it was used to distinguish between HP-UX and Linux in quota-fs.h. Deleting lines 26-28 and 30 from dovecot-1.1.6/src/plugins/quota/quota-fs.h fixes the problem for HP-UX, but of course a real fix would need to add a more current method of distinguishing between Linux and HP-UX. If there's any more helfpul information you'd like let me know, cheers, Marc configure: ...

[Dovecot] Using namespaces to duplicate mailboxes (Doable?)
by Julio C. Ortega 02 Dec '08

02 Dec '08

Greetings. As part of a new installation of dovecot, we are exploring backup options, and wondered if it's at all possible to define a couple of namespaces where messages get duplicated to be saved in another disk for fast recovery. (we do not intent to load balance between the two, all we would like is to see if it's possible to have duplicate mailboxes so to keep a fast working backup _besides_ normal methods: tape, external disk, etc.) The whole idea behind this would be that in case of a major failure of the array holding the mailboxes, a fast working backup can be put in place. Other thing we would like to know (and i reckon it's a long shot) if it's possible to "hide" this mailbox copy from the IMAP clients, so as to prevent any user from subscribing _again_ to the same folders. Naturally this last thing is to be considered only if the former (mailbox copy trough namespaces or other dovecot _internal_ method) it's at all possible. Any feedback or better ideas are totally welcome. -- --------------------------------- Julio C. Ortega Grupo de Infraestructura ONUVA | Integración de Sistemas http://www.onuva.com

[Dovecot] data retention and e-discovery rules
by Trever L. Adams 02 Dec '08

02 Dec '08

Hello All, I am in the United States where we have e-discovery rules. Some organizations have to retain data for a certain amount of time, others are required to have a data retention policy. This means that while it should probably be possible for a user to "delete" an email so they do not see it. The server needs to store it, possibly in a tree that mirrors the folder setup of the user (so if it is in "Sales" folder, it should move to namespace "hidden", or similar, in folder "Sales"). Is there anything like this in dovecot? Is it possible to use cron jobs to see when the message was deleted (Maildir) and erase it based on policy? (Python scripts are fine if the users password isn't needed.) Thank you, Trever Adams

[Dovecot] symlink() failure in 1.2 managesieve
by Bruce A. Mallett 02 Dec '08

02 Dec '08

I've been simultaneously learning about dovecot and experimenting with the 1.2.alpha4. To start I built an rpm under CentOS 5.2 from: dovecot-1.2.alpha4.tar.gz dovecot-1.2-managesieve-0.11.2.tar.gz dovecot-1.2.alpha4-managesieve-0.11.2.diff.gz dovecot-1.2.alpha4.tar.gz dovecot-1.2-sieve-0.1.2.tar.gz and then setup with mysql to use virtual users. Mail-wise, it all works. :) Where I'm having trouble is with the managesieve part. I find that when I activate a sieve script I get a symlink() failure message in /var/log/maillog similar to this: Dec 2 05:12:47 hostname dovecot: MANAGESIEVE(account(a)hostname.com): sieve-storage: Creating symlink() hostname.com/account//.dovecot.sieve to /usr/local/virtual/hostname.com/account/sieve/Test.sieve failed: No such file or directory I began to chase this first by inserting i_info() calls into various points of the managesieve build and later by attaching to the process with gdb. I can see that in sieve_storage_script_activate() the storage->active_path member is incomplete (i.e., is not a full, absolute path name) and the cwd is "/tmp", thus the symlink() call fails. Based on what I've been reading in the documentation, shouldn't the system have resolved the "home" area for the mail to be the same as what is determined for the virtual user mail area? Using the README in the alpha4 package I've found that I can get it to work by adding the following after the "protocol manageseive {}" section: plugin { sieve=/usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage=/usr/local/virtual/%d/%n/sieve } While that helps, I'm a little confused as to why I need to do this. I believe that the documentation states that the sieve defaults to .dovecot.sieve under the MAIL_LOCATION directory. So it is not clear to me if I am doing something wrong, if there is an oversight in the software and/or documentation (or perhaps my reading of it), or is it really necessary to specify the same information multiple times? - Bruce Here is some output that may be of use: -bash-3.2# dovecot -n # 1.2.alpha4: /etc/dovecot.conf # OS: Linux 2.6.18-8.1.8.el5xen x86_64 CentOS release 5.2 (Final) ext3 info_log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s managesieve 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_executable(managesieve): /usr/libexec/dovecot/managesieve-login max_mail_processes: 100 first_valid_uid: 150 last_valid_uid: 150 mail_location: maildir:/usr/local/virtual/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve auth default: mechanisms: plain digest-md5 debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf plugin: sieve: /usr/local/virtual/%d/%n/.dovecot.sieve sieve_storage: /usr/local/virtual/%d/%n/sieve ----- -bash-3.2# grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-mysql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=postfix default_pass_scheme = MD5-CRYPT user_query = \ SELECT maildir as home, 150 AS uid, 12 AS gid FROM mailbox WHERE username = '%u' password_query = select password from mailbox where username='%u'

[Dovecot] Feature request: Force leave copy on server
by Bárður Háskor 02 Dec '08

02 Dec '08

It would be very nice, if I could force users to leave a copy on the server when using POP3. This is because users primarily use a web interface to access mail (the web interface uses IMAP), but users can also download messages using POP3. Users who forget to set the "Leave copy on server" get all their messages deleted in the web interface, and mostly they don't want (expect) this behavior. Isn't it possible to create another way to tag POP3 messages as deleted without these being deleted in IMAP? Sincerely, Bardur Haskor

[Dovecot] help on MailLocation please!
by Li Wei Nan 01 Dec '08

01 Dec '08

Hi Everyone, I'm now using dovecot with a POP3&SMTP server called JAMES. I want dovecot and james to share the email location. Both dovecot and james can store email in mbox format. However, the james will only store mbox mail repo in a fixed dir, such as: /var/mail/ And it will naming each user's mbox repo by its name, such as /var/ mail/tom or /var/mail/peter, etc. So I have to config dovecot for it to fit the situation. So I config dovecot as: mail_location = mbox:/var/mail:INBOX=/var/mail/%u The inbox get worked now, dovecot can read the mbox file created by james correctly. However, dovecot make each user's Trash, Sent in same directory: /var/mail. So it means all the user just have one Trash, Sent. I've read the Wiki carefully and tried some different config and still cannot get it work. Can anyone gives me some advice on it? Thanks a lot! What I hope to achieve is: - Let dovecot read everyone's inbox at: /var/mail/%u (it's a mbox file, not dir) - Let dovecot store everyone's Trash, Sent in /var/mail/%u/mail Thanks in advance. - Li Wei Nan

[Dovecot] lda logging directive does'nt work...

01 Dec '08

Hi all, I'm using Postfix + Dovecot with system users (/etc/passwd and NIS) + deliver + cmusieve; Here are some relevant lines in conf files : /etc/postfix/main.cf ... mailbox_command = /usr/lib/dovecot/deliver ... /etc/dovecot/dovecot.conf ... protocol lda { postmaster_address = postmaster(a)lri.fr mail_plugins = cmusieve deliver_log_format = msig=%m : Subject=%s : From=%f :%$ } ... I just want deliver to log more than default format...like procmail... but nothing happens...the line 'deliver_log_format' seems to be ignored. Any idea ?

[Dovecot] Dovecot POP3 problem: Authentication suddenly fails until dovecot gets restarted
by Carsten Buchenau 01 Dec '08

01 Dec '08

Hi, I am running dovecot with postfix and OTRS2 on a fresh Ubuntu 8.10 Server system. OTRS2 is configured to poll new email to otrs-incoming@localhost via POP3 every 5 minutes. It works, but after approximately 20 hours it suddenly stops working and only a restart of dovecot helps. The outage starts at different times during night (00:15 on Thursday, 1:15 on Friday, 3:20 on Saturday). I checked all cron-jobs, but couldn't find anything matching. Anyone any idea? Thanks, carsten Mail.log: Nov 29 07:10:13 wombat dovecot: auth-worker(default): pam(otrs-incoming,127.0.0.1): pam_start() failed: Critical error - immediate abort Nov 29 07:10:14 wombat dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<otrs-incoming>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Dovecot.conf: protocols = pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol managesieve { sieve=~/.dovecot.sieve sieve_storage=~/sieve } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } /etc/pam.d/dovecot: #%PAM-1.0 @include common-auth @include common-account @include common-session Manual test of POP3 Authentication: root@localhost:/etc/pam.d# telnet localhost 110 Trying 127.0.0.1...

[Dovecot] Relay-Ctrl, error message
by Wouter van der Schagt 30 Nov '08

30 Nov '08

Hi all, I'm trying to get Relay-Ctrl to work (as explained on http://wiki.dovecot.org/HowTo/PopBSMTPAndDovecot) however when i add: mail_executable: /usr/local/bin/envdir /etc/relay-ctrl /usr/local/bin/relay-ctrl-chdir /usr/local/bin/dovecot-settcpremoteip /usr/local/bin/relay-ctrl-allow /usr/local/libexec/dovecot/imap to /usr/local/etc/dovecot.conf I get the following error message when doing dovecot -n Error: Error in configuration file /usr/local/etc/dovecot.conf line 126: Expecting '=' Fatal: Invalid configuration in /usr/local/etc/dovecot.conf So I'm guessing i misplaced the line somewhere in the config file. Where should it be placed? Does it work for both pop3 and imap? Sincerely, - Wouter van der Schagt

[Dovecot] Cache details
by Warren Baker 30 Nov '08

30 Nov '08

Hi All, Is there any specific details we can extract from dovecots authentication cache (besides Authentication cache hits)? Reason i am asking is because we had a mysql user account which was returning a unknown user account. Fixing the one value in the sql result didnt have any affect and Dovecot was still returning an auth failure for the user after 24 hours had elapsed, even though auth_cache_negative_ttl was set to 120. Restarting Dovecot or a SIGHUP on dovecot-auth sorted out the problem. It would be useful if we could interrogate the cache somehow to see what cache entry is been hit. Auth cache settings are as follows: auth_cache_size = 51200 auth_cache_ttl = 2100 auth_cache_negative_ttl = 120 Any suggestions appreciated. Thanks, Warren

[Dovecot] INTERNALDATE call, timezone randomly changes
by Guy 30 Nov '08

30 Nov '08

Hi guys, I've run into an odd little problem. We use SquirrelMail as the basis for our webmail. Recently I've had a user complaining that the "Received" time on mail in the Sent folder has changed between logins. The change is always been by +1 hours or -5 hours. While checking, our developer had a time changed by +2 hours. On refresh it changed back. He poked through the code and it looks like SquirrelMail gets the received date via an IMAP command: A003 FETCH 1:10 (INTERNALDATE FLAGS BODY.PEEK[HEADER.FIELDS (To Content-Type Subject Date)]) I'm running dovecot 1.1.6, and I'm wondering how that function gets the date and time? If I can isolate the source of the timezone I can try and correct it. The server time shown by "date" is correct and /etc/localtime is /usr/share/zoneinfo/Europe/London (which is correct - I've also se the timezone in /etc/conf.d/clock is set to "Europe/London" now), so I'm wondering where else the information could be coming from? Thanks for any information you can give me to help isolate the problem. Guy -- Don't just do something...sit there!

[Dovecot] v1.2.alpha4 released
by Timo Sirainen 30 Nov '08

30 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha4.tar.gz.sig Note that there are significant changes in this release from alpha3 and I haven't tested everything extensively. Be careful. The next release will hopefully be v1.2.beta1 with a feature freeze. Most importantly shared mailboxes and IMAP ACLs are finally supported. This is mainly thanks to the Kolab people (looks like I forgot your names from NEWS file, the next release will have them). I'll have to write a wiki page about ACLs, but the main thing you need to know is that if you want shared mailboxes to be LISTable by other users, you'll need to specify acl_dict. If you don't expect many shared mailboxes, a file backend is the easiest, but you could also use SQL or Berkeley DB. With a file backend you could also create per-domain files, which will improve performance if you don't need cross-domain shared mailboxes. You could do this with e.g.: acl_file = /home/virtual/%d/shared-mailboxes Also full text searching works now better with virtual mailboxes. Previously the fts would have duplicated the indexes for virtual mailboxes. Now with Solr backend it searches the original mailboxes directly. Although this is still missing some optimizations and also it doesn't check first if mails are missing from the original mailboxes, so it may not find everything. Also this still doesn't work with Squat backend.. Anyway, a bit more code and Dovecot will have fast full text searching from all mailboxes (virtual * mailbox). I implemented also draft-gulbrandsen-imap-response-codes-04, which adds some [codes] for all IMAP command failures, which should make it possible for clients to figure out more easily what caused the failure. Hopefully the draft won't change much anymore. :)

[Dovecot] Dovecot as proxy for M$ Exchange mailboxes
by Axel Schmalowsky 30 Nov '08

30 Nov '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, is there a way to use dovecot as proxy for m$ exchange mailboxes? Currently, our clients not only can login to their mailboxes with their e-mail address but also with their accountid. Both the clients e-mail address and accountid are stored in ldap. Now I need a way to let dovecot rewriting the client's accountid to the respective e-mail address. Is this possible with the proxy-feature of dovecot? Any hints would be appreciated. - -- Freundliche Grüße / Kind regards Axel Schmalowsky Platform Engineer ___________________________________ domainfactory GmbH Oskar-Messter-Str. 33 85737 Ismaning Germany Telefon: +49 (0)89 / 55266-356 Telefax: +49 (0)89 / 55266-222 E-Mail: aschmalowsky(a)df.eu Internet: www.df.eu Registergericht: Amtsgericht München HRB 150294, Geschäftsführer Tobias Marburg, Jochen Tuchbreiter -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJL+JKsuqpduCyZM0RAoFUAJ9mPbv5eI5xP54YhwlmOs40F1RxDQCgir5l jCdaNeXKO8FnOCxaKSI7S4E= =m5WN -----END PGP SIGNATURE-----

Hello, Thank you for this link, but this is not what I want. Dovecot is only used for imap. Currently, authentication works fine, but new fields are created in a subdirectory. Example: /var/vpopmail/domains/0/domain.com Once authenticated, I just want to be in chroot /var/vpopmail/domains/0/domain.com/user and not in /var/vpopmail/domains/domain.com/user I explained that vpopmail which manages the creation of areas and I can not influence the subdirectory.

[Dovecot] ManageSieve and invalid scriptname
by Miguel Filho 28 Nov '08

28 Nov '08

Hello there, I have been using pysieved and avelsieve and it has been working great. I decided to do test with the ManageSieve patch and got this problem: Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: using active sieve script path: ~/.dovecot.sieve Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: using sieve script storage directory: ~/.sieve Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: relative path to sieve storage in active link: .sieve/ Nov 27 17:21:29 cambui dovecot: MANAGESIEVE(miguel): sieve-storage: Active sieve script symlink /home/admsis/miguel/.dovecot.sieve is broken: invalid scriptname (points to .sieve/phpscript). Well as you can see, a file without the .sieve is not welcome :-( I checked the RFC and there is no requirement for a .sieve file extension when considering scriptnames. http://tools.ietf.org/html/draft-martin-managesieve-12#section-1.6 Is this a misplaced restriction or it really should be enforced for any reason? I hope that this can be tolerable, or I will have to rename a lot of scripts and remove all hardcoded "phpscript" strings from avelsieve :-( Regards and thanks for the great work. Miguel

[Dovecot] Sieve and global scripts
by Allan Cassaro 28 Nov '08

Hi Stephan Bosch, there's any way to make the dovecot deliver agent (with sieve) load a "global sieve script" before load the user sieve file? I want to create some rules for every one, like: "if header contais: IS SPAM, move to SPAM BOX"... I made this today with a couple of "sed + awk" and a wraper for managesieve-login... but, this is definily not the best way to do this... This is possible to do?

[Dovecot] Namespaces and shared folders
by bbell2000 28 Nov '08

28 Nov '08

I had a working dovecot install before I tried to implement shared folders using namespaces. I added the following to /etc/dovecot/dovecot.conf: namespace private { separator = prefix = inbox = yes } namespace public { separator = / prefix = location = maildir:/home/public/shared/Maildir } </pre> I created my shared folder using the maildirmake command that came with qmail: maildirmake -S /home/public/shared/Maildir maildirmake -s write -f online /home/public/shared/Maildir chown -R dovecot:shared /home/public/shared find /home/public/shared -type d -exec chmod 0777 {} \; find /home/public/shared -type f -exec chmod 0666 {} \; At this point, the online folder shows up as a subscribable folder in Thunderbird. I can subscribe to online and I can still access my Inbox. But I can't get to any of the folders in my Inbox (Trash, Drafts, etc.). I can access these folders if I comment out the namespaces and revert to the default behavior. There are no clues in mail.err, mail.info or mail.warn -- the only messages are the ones written when my client establishes a successful IMAP connection. What did I do wrong? -- View this message in context: http://www.nabble.com/Namespaces-and-shared-folders-tp20727713p20727713.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] UIDL question
by Wouter van der Schagt 28 Nov '08

28 Nov '08

Hi all, I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem. Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time. I understand this must be because the email client "sees" a different UIDL and downloads the message again. Looking at the 1.0 configuration, i do not see a "pop3_uidl_format" setting. So was wondering how the UIDL is generated. Is anybody aware of a conversion script that properly maintains the UIDL? Or am I misisng something else here? Sincerely, - Wouter van der Schagt

In my case, the cause was a large spam message (above the configured MaxMessageSize parameter for DSPAM) that was skipped during tests and thus no signature was added. Might this be true in your case? As a general suggestion for Johannes: maybe it is better to ignore this error silently, just move the message and don't call DSPAM? > I checked that the given location for the dspam executable is correct, > that the user executing it (dovecot?) is actually able to execute dspam > and that dspam trusts this user.

[Dovecot] Can I import RFC822 messages into Dovecot from file system
by bbell2000 27 Nov '08

27 Nov '08

I'm returning to qmail and dovecot after having suffered a complete failure with a different mail system and I'm now trying to figure out the easiest way to recover our messages from the failed system. The messages are stored as RFC822 in individual files and I can easily identify which message belongs to whom. I have qmail and dovecot configured to use Maildir format. I know I can probably write a script that resends the messages... but in addition to adding another layer of transport headers I really don't want, it's going to be way slow unless I disable my current content filters. I'm new to dovecot and what's got me hung up are the indexes that dovecot maintains in each user's directory. Otherwise, I'd probably try copying the messages into Maildir/cur just to see if it worked. I could sure use some ideas about an efficient, reliable means of getting our old messages back. Thanks. -- View this message in context: http://www.nabble.com/Can-I-import-RFC822-messages-into-Dovecot-from-file-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Antispam plugin + script sieve
by Allan Cassaro 27 Nov '08

27 Nov '08

Hi guys, I will start a little script that receive via antispam plugin an email, extract the "from" and "return-path" and create alter the sieve script of the user that send the e-mail. Well, I don't speak english very well (I speak like Borat!!!), but with some examples is better to understand: 1) Some user move an "undesirable" mail to "Automatic Block" folder 2) The antispam plugin call my script 3) The script parse the e-mail and extract the from and return-path mail 4) A rule is added to ~/.dovecot.sieve to dicard messages that came from that e-mail 5) If the user remove the mail from "Automatic Block" folder, the script remove this rule So, my question is: anyone is working on something similar with this?

[Dovecot] deliver segv on sieve redirect
by Andy Howell 27 Nov '08

27 Nov '08

Hello, I've been trying out the bleeding edge, 1.2.alpha4. I'm having a problem with deliver and dovecot-1.2-sieve-0.1.1. I get a segv on this sieve script: require ["fileinto", "reject", "vacation", "envelope", "regex"]; if header :contains "subject" ["urgent"] { redirect "someone(a)somewhere.net"; fileinto "test"; } Seems its happening on the "redirect". If I put the fileinto before the redirect, the fileinto works. I tried putting extra debug statements in plugins/lda-sieve/lda-sieve-plugin.c right after the sieve_execute in lda_sieve_run, but it never prints anything. I'm guessing thats the right place. Its quite possible there is something amiss in my setup. My logs show: Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: using sieve path: /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: opening script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: executing compiled script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin postfix/pipe[17027]: 0CA895CB3A: to=<andy(a)x.y.org>, relay=dovecot, delay=0.41, delays=0.33/0.01/0/0.07, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/libexec/dovecot/deliver") Thanks, Andy

[Dovecot] Released Sieve v0.1.2 (important bug fixed)
by Stephan Bosch 26 Nov '08

26 Nov '08

Hello Dovecot users, Today, Andy Howell tripped an important bug in the Sieve interpreter that makes it crash when redirect is executed. That is why I quickly release yet another new version to provide a fix for this bug. I really should prevent this from happening again in the future by extending the test suite to test the execution of actions. Changelog v0.1.2: - Fixed important bug in the redirect action (and probably other actions like reject and vacation that only send messages). This was a bug in the handling of context information during the execution of actions. It caused the sieve interpreter to crash with a segfault when redirect was executed. The release is available here: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz.sig Refer to the initial release mail for more information: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

Only enabling it without using it (with addflag) is enough to stop sieve from working. All my emails will be delivered in my inbox despite the rules I use. If I remove imapflags, everything is working fine. And I don't see anything in my logs explaining the problem.

[Dovecot] Released Sieve v0.1.1 and ManageSieve v0.11.2 for Dovecot v1.2.alpha4
by Stephan Bosch 25 Nov '08

25 Nov '08

Hello Dovecot users, Since the first release of the new Sieve implementation, not that many bugs were reported. This is probably due to the fact that it is not tried yet by that many people. In the mean time, I did find and fix some more bugs myself, I adapted to changes in Dovecot, wrote some more documentation and started work on the enotify extension. Both Sieve and ManageSieve were changed to match API changes in Dovecot and therefore older versions will not compile against the new Dovecot release. Likewise, these new Sieve and ManageSieve releases will not compile for older Dovecot versions. Changelog Sieve v0.1.1: * Re-enabled support for compiling against dovecot headers. Much like cmusieve, command line tools like sievec and sieved are not compiled in this case. * Started implementation of enotify extension. Not anywhere near finished though. * Adapted to changes in Dovecot on various occasions, making this release dependent on Dovecot >= v1.2.alpa4. + Improved logging of errors at specific occasions and added debug messages to find script execution problems quicker. + Removed code duplication between command line tools and the test suite. Also restructured the sources of the tools. + Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP. + Created man pages for the command line tools. These are automatically installed upon 'make install' + Incorporated Valgrind support into the test suite and fixed a few memory leaks in the process. - Fixed compile error surfacing for gcc3.4. Forgot mask argument for the open() system call when the O_CREAT flag is specified. Bug found by Sergey Ivanov. - Fixed bug in the sievec tool. -d output was always written to stdout. - Fixed important bug in the imap4flags extension. When no :flags argument is specified, the previous version would always use the final value of the internal variable to set the flags. This means that modifications to the internal variable also affected the bare fileinto/keep actions executed earlier. This does not comply to the RFC. - Fixed bug in the include extension's import/export commands. Duplicate import/exports caused problems. - Fixed bug in the handling of non-existent scripts.

[Dovecot] v1.1.7 released
by Timo Sirainen 25 Nov '08

25 Nov '08

http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz.sig I should have released this earlier since v1.1.6 had that annoying startup problem, but surprisingly few people complained about it so I kind of forgot about it then. BTW. v1.2 progresses nicely. Now that shared mailboxes are finally fully supported, there aren't any widely used IMAP features missing from Dovecot. v1.2.beta1 shouldn't be in too distant future anymore. * IMAP QUOTA extension now returns "MESSAGE" quota, not "MESSAGES". This makes Dovecot now RFC 2087 compliant. Hopefully this change doesn't break anyone's Dovecot-specific quota checking code.. + Added !include and !include_try directives to config file reader. Note that !include doesn't currently work with deliver. The main point here is that ssl_key_password can be placed to a different file with !include_try that deliver can just ignore. + More error/debug message logging improvements. - v1.1.6 gave "userdb didn't return a home directory" error at startup - Some config file parsers (deliver, passwd-file, acl, trash) ignored the file's last line if it didn't end with LF. - fts: SEARCH SUBJECT didn't search messages that weren't already in fts index. - fts-solr: Don't assert-crash if we couldn't connect to Solr. - IMAP: Mailbox deletion gave an error, but still worked, if mails' control directory wasn't the same as index directory. - Several fixes to rarely used mailbox list layout configurations.

[Dovecot] PLAIN password scheme question
by Dmitri V. Ivanov 24 Nov '08

24 Nov '08

Hi, ppls There is some problem with using passwd-like file and plaintext passwords within it. Let's assume we have users speaking russian. They think and remember their passwords also within russian words (they just not change keyboard layout before entering their passwords). So if the user has password like ":jgf" (meaning "ass" in russian) and passwords are stored into passwd-like file within {PLAIN} scheme what will happen? ===== user:{PLAIN}:jgf:1234:1234:.... ===== Isn't it a reason to implement something like {HEX} and why?

But why do you think there's a bug in Dovecot? Note > that Dovecot never even sees this value. It's the kernel that enforces > it, Dovecot simply reacts to a write() failure. The logs stating the "File too large" errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets "File too large" error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag

[Dovecot] pam auth fail considered mail.error?
by David Halik 24 Nov '08

24 Nov '08

Hello all, Following the Dovecot wiki and migration help, we recently migrated our core IMAP systems from Courier to Dovecot on Solaris. So far it's been working great, but I have one issue that I'm curious about. Just as the docs mention, we also use "syslog_facility = mail" for logging. Unlike in the past, failed PAM auth attempts are now getting logged as mail.error: Nov 24 08:34:34 xxx.xxx.xxx.xxx dovecot: [ID 107833 mail.error] auth-worker(default): pam(dhalik,xxx.xxx.xxx.xxx): pam_authenticate() failed: Authentication failed Is there a reason for this, or a way to configure this behavior? mail.error is a little harsh for pam auth failures and I would think that the auth channel would be used instead similar to other processes (sshd, courier, etc) I'd like to continue using the mail facility, but if every time there is an auth error Dovecot reports to mail.error, my consoles and legitimate error logs are going to be full of something considered a non-issue by most. Any help is appreciated, thanks. -Dave -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] two dovecot server using the same file system
by Osvaldo Alvarez Pozo 24 Nov '08

24 Nov '08

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there a way of solving this issue?? Thanks

Hi, Setting mailbox_size_limit to 0 made deliveries possible. a limit of 2000000000 (<2GB) also did not show the errors. Thank you ! :) My issue is fixed but deliver might have a bug, so I will explain things, sorry for not being clear previously. Old mail server was 32 bit(an old version of debian) and used procmail for deliveries, that setup worked with the given limit of 5GB and mailbox sizes above 1GB. After migrating to an 64 bit server (debian etch) and dovecot's deliver, the stated delivery errors appeared for mailboxes above 1 GB. As I stated at the beginning of my reply, setting mailbox_size_limit below 2GB made deliveries possible. I tried with edge values, mailbox_size_limit=2147483648 (exactly 2GB) would give the following error in postfix logs: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit A limit of 2147483648 - 1 worked fine. There are two distinct bugs probably, one in postfix and one in dovecot. I guess this is result of using integer values for size limit. values greater than 2GB would wrap and cause warnings in postfix. Probably, my previous limit of 5GB would confuse things and no error was reported. (I don't know how, 5GB cannot be stored in an unsigned int, double overrun makes it within limit ? :) ) Maybe moving to "long long int" for mailbox file size is a possible solution. -- Gokdeniz Karadag

[Dovecot] OT: Run Sieve On A Mailbox Manually
by Neil 22 Nov '08

22 Nov '08

(Apologies for being offtopic.) The subject basically says it all...does anyone know of a tool to run a sieve script on a mailbox (in particular, Maildirs) manually? Ideally, I'd like to do it without adding a bunch of new headers to the mail. So, could I just do a find (or for-loop, if it was just one maildir) command and pipe all the mails into deliver..? Thanks, Neil.

[Dovecot] mail_privileged_group not working for dotlock files (1.1.6)

Hello, Running dovecot 1.1.6 on centOS 5 and RHEL 5. With the settings: pop3_lock_session = yes mail_privileged_group = mail mail_location = mbox:~/:INBOX=/var/spool/mail/%u mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl and /var/spool/mail permissions: drwxrwx--x 2 root mail 4096 Nov 19 10:16 mail/ Trying to connect via POP3 results in this error: --- Nov 19 09:31:01 lexiconn2 dovecot: child 32127 (pop3) killed with signal 11 Nov 19 09:31:01 lexiconn2 dovecot: POP3(cerberus): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Nov 19 09:31:01 lexiconn2 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=1.2.3.4, lip=5.6.7.8, secured --- The docs seem to indicate the above config / settings should work. Is this a bug? The reason we have dotlock as the primary format is due to procmail LDA from sendmail: --- procmail -v 2>&1|grep Locking Locking strategies: dotlocking, fcntl() --- I assume we have to make the "mbox_write_locks" match the procmail locking... Thanks. Rob

[Dovecot] expire-tool fails if mail_location contains %h
by Thorsten Vollmer 21 Nov '08

21 Nov '08

Hi Timo, not long ago you fixed a bug regarding the expansion of ~/ in mail_location that prevented expire-tool from working correctly. A similar problem exists if mail_location contains %h: expire-tool will use the wrong path to access the mailbox. After replacing %h with ~, expire-tool works as expected. Why are there two variables for the home directory? Maybe the use of %h could be discouraged, sparing you some problems. Regards, Thorsten

[Dovecot] Separate quotas not displayed correctly
by Laurent Blume 21 Nov '08

21 Nov '08

Hello all, My system is set up to have quotas both on /var/mail, where emails are received, and on /export/home, where users' homedirs are. But the client (Thunderbird) shows the same /export/home values both for the Inbox and for the folders in the homedir, so a user cannot know where she stands on her /var/mail use. This is Dovecot 1.1.5. As per the wiki, the dovecot.conf file contains this: quota = fs:INBOX:mount=/var/mail quota2 = fs:Others:mount=/export/home A sample user: # quota -v testimap Disk quotas for testimap (uid 1143): Filesystem usage quota limit timeleft files quota limit timeleft /export/home 6490 10000 15000 0 0 0 /var/mail 0 20000 25000 0 0 0 When Icheck the Quota tab in the Properties of the Inbox, the field contains "Others", and the value are 6490 out of 10000. Any idea why this doesn't display the value of /var/mail?

[Dovecot] Dovecot and Bogofilter
by Matthias-Christian Ott 21 Nov '08

21 Nov '08

Hi, on my small Xen-virtualised server with 48 MiB RAM I use Postfix and Dovecot, because the Debian administrators dislike qmail [1], which is in my opinion despite some maintainability and code quality issues a quite well designed software, because it mostly follows the UNIX principles. Postfix is not able to sort my E-Mail into different Maildir folders and after I looked at procmail's source code, I decided to use Dovecot's LDA, because it supports sieve via a plugin. All in all it worked after some tweaking and Dovecot is now responsible for authentication and delivery. Furthermore I want to setup a spam filter and due to the memory constraints I decided in favour of bogofilter (I made no real world tests, but the authors claim that it's fast and has a small memory footprint). My first idea was train bogofilter via a cronjob that runs bogofilter for each E-Mail in my spam folder and deletes them afterwards. Then I stumbled upon the dovecot antispam [2] plugin and quickly wrote a backend for bogofilter. During the development I realised that bogofilter has to update the X-Bogosity header of the reclassified E-Mails. Johannes Berg told me that he wasn't sure whether dovecot would be able to do this and recommended to ask this on the mailing list. An other problem is that each mail needs to be initially classified and due to the fact that sieve is not able to execute external programmes, deliver has to do this task. I'm currently thinking of possibilities to implement this, so far I came up with the following: 1. Write a generic pipe plugin which can execute an arbitrary number of programmes. The problem with this is that I'm not sure how to integrate this is in Dovecot's configuration file. I thought of something like this: pipe = prg1 | prg2 2. Write a bogofilter-specific plugin for this. Anyhow I would like to take this opportunity to criticise Dovecot for being a bloated (unnecessary abstractions, verbose, pseudo object-oriented, ...), non-suckless [3] and non-unixish (plugin architecture, monolithic design, ...) software which in return works quite well and stable so far. I appreciate any suggestions, ideas or criticism. I would really like to finish configuring my mail server as soon as possible. Regards, Matthias-Christian [1] http://smarden.org/pape/Debian/1215531259.4854_332.werc [2] http://johannes.sipsolutions.net/Projects/dovecot-antispam [3] http://www.suckless.org/common/

[Dovecot] nfs_flush_fcntl failed: No locks available
by Mark Zealey 21 Nov '08

Dear dovecot list: Could any experts help me on the configuration of per-user for dovecot on FreeBSD 7.x with postfix-2.5.4,1. I followed the howto of http://workaround.org/articles/ispmail-etch/, it is an excellent file, my mailserver worked very well. When I configured per-user quota plug-in, quota_rule with 20MB limits can not be overrided by the Mysql query statement, Although I followed the document at : http://wiki.dovecot.org/Quota. Below is the output of dovecot --version, dovecot -n and dovecot-sql.conf. Could any experts help me? Thanks in advance !

[Dovecot] Per User Quotas
by Peter Fraser 21 Nov '08

21 Nov '08

HI All Asking for a little patience and a bit of help here. I'm using dovecot-1.1.3_1 with postfix and squirrelmail. I have implemented a global quota successfully. That works fine. I want to now implement per user quotas. So far I have read the howto in the documentation and searched several threads but can't seem to get it working properly. My LDAP server is Windows 2003 Active Directory. Is there any documentation specific to AD that I could look at or any other doc that could help me? My last effort was to put this in dovecot-ldap.conf user_attrs = streetAddress=quota_rule4=*:storage=%$M ,=uid=1002,=gid=1002,=home=/home/vmail/%u and this in dovecot.conf in addition to the other quota rules. quota_rule4 = *:bytes=%$ I then put the quota in the streetAddress area of AD. I'd certainly appreciate any help. Thanks.

[Dovecot] make archive emails undeletable?
by Rob Nichols 21 Nov '08

21 Nov '08

I've been using dovecot for a year or two now, and really like it. I have a fairly simple setup, but I think it's time to get a little more advanced. I keep an "archive" of all my email, both sent and received. Every once in a while I get confused, and accidentally delete something from my archive. I also worry that I'll misconfigure a mail client some day and accidentally wipe out my "trash" folder. I would like some way to prevent deletion in several mailboxes. Is that possible? It looks like ACL could do this, but I can't quite figure out where to start. Any pointers would be greatly appreciated. Thanks, Rob

[Dovecot] Auth Issues - Urgent - Help!
by David Cunningham 21 Nov '08

21 Nov '08

After a few hours of running, I get tons of the following errors in my logs: dovecot: Oct 08 07:41:50 Error: auth(default): ldap(user(a)domain,x.x.x.x): Request queue is full I removed the username and IP, obviously. Any idea how to stop this? I have about 5 Thousand users using horde that login ever 1-5 minutes to refresh their page. I assume it is a setting, but I am confused as to why it doesn't happen almost right away. It seems to take some time to build up. Please help! This is taking my webmail system down hourly.

[Dovecot] Error message in logs since 1.1.6 upgrade
by Guy 21 Nov '08

21 Nov '08

Hi, I've got two imap boxes, one is running 1.1.5 and hasn't exhibited the error below, but the one that's been upgraded to 1.1.6 is showing them. Nov 14 16:06:31 mink dovecot: imap-login: Disconnected (no auth attempts): rip=x.x.x.x, lip=x.x.x.x, TLS handshaking: SSL_accept() failed: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac If this isn't already a known error, is there any extra data I can collect that would help diagnose what's causing it? I haven't a clue where to start with this sort of debugging I'm afraid. Thanks Guy -- Don't just do something...sit there!

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by BrunoM 21 Nov '08

21 Nov '08

Hello, I just read your message about sieve and body-extension in Dovecot. Do you have news on that topic? I just have to filter mails containing a particular text fragment, and I cannot do without sieve body, I think.. Thank you for any clue you'd be able to give me ! Regards, Bruno --- Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott

[Dovecot] %d in deliver
by Mark Zealey 21 Nov '08

21 Nov '08

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain as well as the user, however deliver doesn't seem to pick this up. Is there any way that you could extend deliver to make it either pick up the domain (or correct username) from the command line, but not do an authdb lookup; or get it to read the domain from an environment variable (or be able to print the contents of an arbitrary environment variable in a formatted string)?

[Dovecot] namespace public / namespace shared - question
by Michal Soltys 21 Nov '08

21 Nov '08

After looking through wiki/config/list I'm still not sure, what exactly is the difference between those two. Even all the examples in dovecot's wiki don't have a single "namespace shared" anywhere. And there's only short mention about the difference in dovecot.conf . Peeking into rfc2342 - would shared namespace relate to "Other Users' Namespace(s)" and public namespace to "Shared Namespace(s)" ? Does perhaps the difference only lie on the client side, depending on the namespace it's asking, while functionally it's the same from the perspective of dovecot ?

[Dovecot] CRAM-MD5 and proxy_maybe
by David Jonas 20 Nov '08

20 Nov '08

When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn't it work with proxy_maybe? This works: password_query = \ SELECT NULL AS password, host, CONCAT(user,'@',domain) AS destuser \ 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy \ FROM accounts WHERE class='pop' AND domain='%d' This doesn't work if proxied and CRAM-MD5 auth: password_query = \ SELECT \ CONCAT(user,'@',domain) AS user, password, \ host, 'Y' AS proxy_maybe, \ target AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM accounts WHERE \ class='pop' AND domain='%d' AND user='%n' \ LIMIT 1 Thanks, David

I'd like to take advantage of RFC5229 match variables (it would reduce the number of rules I have by an order of magnitude); however, the required extension isn't supported yet. Am I mistaken? If not, are there plans to support it?

[Dovecot] Unbreakable NFS locking issues...
by Rod Treweek 20 Nov '08

20 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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 login_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.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 plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly, greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] New message notification
by Juan Asensio Sánchez 19 Nov '08

19 Nov '08

Hi What is the best option to notify a user that a message has arrived? The intention is to write a script that connects to a jabber server and checks if the user is online, so then a message is sent to user notifying him that he has received a new message. The solution should be compatible with Sieve filtering, so the script should not be executed when the message is moved to the SPAM folder, or pass to the script an argument specifying the folder where the message has been saved. Regards and thanks in advance. Juan Asensio Sánchez - http://www.nutum.es

[Dovecot] Solving CVE-2008-4870
by Michal Hlavinka 19 Nov '08

19 Nov '08

Hi, we're trying to solve CVE-2008-4870 = rhbz#436287 = dovecot.conf is world readable - possible password exposure. This problem seems to be little more complicated than we thought. dovecot.conf can contain passphrase for ssl key, which is available for everyone since dovecot.conf has world readable permissions. (In CVE's description is note that it RHEL's/Fedora's problem, but it affects all systems imo) We was thinking about few ways how to fix it: 1) 0640 permissions for dovecot.conf - but it can became not readable for dovecot 2) 0640 root:mail and set deliver to group mail with sgid - possible security problem 3) don't store passphrase in dovecot.conf, just ask for it when dovecot's started - can hang boot process, not good As part of investigating, I've found dovecot is storing all variables in environment variables - it means even passphrase? I'm not completely sure, but all variables can be read via /proc/<pid>/environ (I don't know if it becomes readable in some circumstances.) Is there any plan to solve this problem? Cheers, Michal

[Dovecot] patch: list shared namespace
by Bernhard Herzog 19 Nov '08

19 Nov '08

Hi, I've been working on a patch for dovecot 1.2 from the Kolab branch (http://hg.intevation.org/kolab/dovecot-1.2_kolab-branch/) that implements listing of shared namespaces. I've got something that works in some basic way but is still missing some pieces. See the attached patch, which also contains some installation and configuration notes. Implementation notes: One of the main problems the patch addresses is getting a list of all users that have mailboxes the logged in user can see. The patch uses a dict to cache information about which users have at least one mailbox that is visible to other users. The dict doesn't cache which other users, though. The cache entry for a given user is updated whenever the dovecot-acl-list file in the maildir root directory is updated. This ties the implementation to a specific acl backend to an extent, but that shouldn't be a problem at the moment. Another problem is that namespaces for all those users have to be created. The patch does that in shared-storage.c when the shared storage is created. At this stage of development of the patch that works well enough, I think, but it might be better to update the namespaces whenever a list iterator is created. To avoid unnecessary coupling between the shared namespace code and the ACL plugin, the shared namespace code has a hook that it calls when it needs a list of all the users who may have mailboxes visible to the current user. The ACL plugin sets that hook and uses the dict to produce that list. This way, the ACL plugin depends on the shared namespace code but not the other way round and all the dict handling is in the ACL plugin. I'm not sure the new hook is really needed. The patch could perhaps just as well extend the acl_next_hook_mail_storage_created and acl_next_hook_mailbox_list_created functions to do the namespace creation when they're called for a shared storage or mailbox list. Problems: All of my tests so far involved a shared namespace of the form namespace shared { separator = / prefix = users/%%u/ location = maildir:.../var/mail/%%u:... subscriptions = no list = yes hidden = no } Also, let's assume two users, ford and arthur with ford's "INBOX/hhgttg" available to arthur as "users/ford/INBOX/hhgttg". Arthur may not list ford's INBOX, though. In the following the current user is always arthur. I found the following problems: - LIST response includes namespaces the user doesn't really have access to. E.g. if there's another user, zaphod who's made some mailbox available to somebody else, but not arthur, arthur still sees * LIST (\Noselect \HasChildren) "/" "users/zaphod" Not sure it's worth fixing this, though. - List with "%" doesn't list all intermediate mailboxes. On the one hand arthur sees this: x LIST "" "*" ... * LIST (\Noselect \HasChildren) "/" "users/ford" * LIST (\HasNoChildren) "/" "users/ford/INBOX/hhgttg" x OK List completed. OTOH, with "%" only this: x LIST "" "users/ford/%" x OK List completed. cyrus shows x LIST "" "users/ford/%" * LIST (\Noselect \HasChildren) "/" "users/ford/INBOX" x OK List completed. At least Kontact resp. KMail rely on this. - The dovecot-acl-list is not always rebuilt, even when it should have been, AFAICT. In particular, if the file exists but is empty, it's never updated, even when ACL later change. Maybe this is a bug in the Kolab branch.

[Dovecot] Bug in 1.1.4: New line required in ACL files

Hello, just wanted to notify you about a bug i found in 1.1.4 ACL handling: Global ACLs are ignored, when there is no line break (i.e. "owner lr" is ignored while "owner lr\n" works). I didn't track this down to see if the same happens for per-user ACLs, but it should be quite obvious in the source anyways.

Client: Mail.app v.3.5 Server: Dovecot 1.1.6 I've noticed that when I go to "Account Info" in Mail.app, and then to the "Subscription List" tab, Mail.app will spin for a bit, and then give up, without showing any folders and all the buttons are grayed out. Does anyone know if this a Mail.app issue or a Dovecot issue, if there're any work-arounds, and/or if this is something I should be concerned about? Thanks, Neil.

[Dovecot] MESSAGE Quota not RFC2087 compliant
by Braun, Martin 18 Nov '08

18 Nov '08

Hi, the configuration of my Dovecot 1.1.3 quota plugin looks like this: quota_rule = *:storage=1G quota_rule2 = *:messages=1337 this leads to the following GETQUOTAROOT response: 01 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "mbraun quota" * QUOTA "mbraun quota" (STORAGE 6553 1048576 MESSAGES 122 1337) 01 OK Getquotaroot completed. RFC2087 (http://www.faqs.org/rfcs/rfc2087.html) describes the response like as: STORAGE: Sum of messages' RFC822.SIZE, in units of 1024 octets MESSAGE: Number of messages As you can see, the response "MESSAGES" differs from the specified "MESSAGE" which leads to parsing issues on RFC compliant IMAP client implementations. Using *:message=1337 throws a configuration error on Dovecot startup. dovecot-1.1.6/src/plugins/quota/quota.h /* Number of messages. */ #define QUOTA_NAME_MESSAGES "MESSAGES" Greetings, Martin

[Dovecot] ManageSieve SECURITY hole: virtual users can edit scripts of other virtual users (all versions)
by Stephan Bosch 17 Nov '08

17 Nov '08

Hello, While updating the ManageSieve implementation to the latest draft specification I noticed a major omission in the way script names are handled. Essentially, script names are directly appended to the sieve storage directory path and suffixed with '.sieve'. This does not take the use of '../' in script names into account. Therefore, clever virtual users that know the directory structure of the server can read and edit script files of other virtual users with the same system uid. The added '.sieve' suffix prevents further security breach, because only sieve scripts are accessible this way. Note that of course any publicly accessible sieve script is also affected. I am sorry to report that this bug was introduced pretty much from the start, meaning that all versions of the ManageSieve patch/package are affected. To quickly resolve this issue, I provide patches against the existing releases and I release new versions for Dovecot v1.1 through v1.2. The security patches against the existing releases are very small and should therefore also apply to older versions or can be adjusted to apply cleanly with relative ease. The security patches are available as follows: http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-managesieve-v9.3-securit… http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-managesieve-v9.3-securit… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3-security… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3-security… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0-security… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0-security… The security patch for v1.0 is applied against the patched Dovecot tree, while patches for v1.1 and v1.2 are applied against the ManageSieve package. The new releases are available as follows (v1.1 and v1.2 versions have additional changes, read the NEWS files for more info): http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-MANAGESIEVE-v9.4.diff.gz http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-MANAGESIEVE-v9.4.diff.gz… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.4.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.1.tar.gz.s… Refreshed ManageSieve patches for v1.1 and v1.2 are available to avoid confusion, but an existing patched Dovecot should work fine. I hope package maintainers will quickly incorporate the security patches to get rid of this stupidity as soon as possible. Don't hesitate to notify me when there are problems!

[Dovecot] Dovecot error with Symbian mail client
by jeeger＠thenybble.de 17 Nov '08

17 Nov '08

Greetings list, I have recently acquired an Nokia E71 (which comes with Symbian 3rd edition, feature pack 3 I believe). Accessing my emails has worked before, but now, I cannot connect to the mail server any longer. If I enable verbose_ssl, I get the following error in the log: SSL_accept() failed: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message [141.84.69.67] I cannot access my mail, the dialog just closes and the wireless connection ends. I am using dovecot version 1.0.13 and my config is # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl_cert_file: /etc/dovecot/dovecot.crt ssl_key_file: /etc/dovecot/dovecot.pem verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login auth default: passdb: driver: pam userdb: driver: passwd Thanks for your answers! Regards, Jan Seeger PS: I have tested the symbian client with gmail, and it works. So the problem is probably a bug in the communication between the symbian client and dovecot.

17 Nov '08

Hi, I am using dovecot 1.0.10 and pysieved, in a master/slave cluster with ldap (auth_bind=yes). For conceptuals reasons, i would like to keep on the same partition the mailstore + sieve scripts. I have try to set "sieve" and "home" variables under the "plugin" section with an absolute path, and i have tried to override home variable in user_attrs (dovecot-ldap.conf) as well with an absolute path, but in vain. Is there a solution ? sam

[Dovecot] OT: Counting emails in IMAP folders
by Nigel Allen 17 Nov '08

17 Nov '08

Greetings I have a customer who has mail server running dovecot with an IMAP account (Customers) which contains hundreds of folders (one per customer). Looks like this: Customers Fred Smith and Co Joe Blogss Cust-1 Cust-n They have a requirement to report monthly on the total number of emails added to each customers' folder during the month. Basically I need to be able to run some kind of command line query that will give me each of the sub-folder names and the number of emails added to the folder for that month (or other user-specified time period). Any ideas please? TIA Nigel.

[Dovecot] Mailbox Hashing
by Justin Krejci 14 Nov '08

14 Nov '08

First off, the website documentation is really good for Dovecot but while reading I was not able to find anything pertaining to inbox hashing for Maildirs. I saw plenty about hashing the directories that the user mailboxes live in but nothing about specifically hashing an individual user's inbox directory itself. Is there any method for hashing the inbox automatically after say 5,000 messages are stored? Example $Maildir/in/0/message0 $Maildir/in/0/message1 $Maildir/in/0/message2 . $Maildir/in/0/message4999 $Maildir/in/1/message5000 $Maildir/in/1/message5001 etc I am not currently using Dovecot but am interested to know if this is available or does running with 20,000+ messages in a single inbox not affect the performance much? I have looked into other file system tuning techniques such as enabling ext3 dir_index or using ReiserFS (maybe not ReiserFS anymore). There will likely be 15,000 to 20,000 accounts spread out on one or more servers using a 6-drive RAID10 setup. Most accounts are not expected to have high message quantities but there will be lots of concurrent connections via pop and imap (and webmail imap). Any suggestions or feedback would be appreciated.

[Dovecot] Folder aliases
by Daniel L. Miller 14 Nov '08

14 Nov '08

I don't if this has been discussed before - or already implemented - but it would be great if I could define one or more "aliases" for a folder. A particular example might be "Sent" where different (badly-written) clients might have hard-coded "Sent" folder locations like "Sent", "Sent Items", "Sent Mail", "Mail Delivered", etc. - and I'd love to get those consolidated. It would also be nice to show a different set of folders based on the client - or if that's not possible (if the client doesn't identify itself as part of the login sequence) then somehow via login name - maybe by an extension? So where my usual login might be "user(a)domain.com", and that would continue to be supported as the default login, I could now have "user(a)domain.com+thunderbird", "user(a)domain.com+mobile", etc.? -- Daniel

[Dovecot] New Dovecot server buildout review
by David Jonas 13 Nov '08

13 Nov '08

Hello Everyone, I have the opportunity to do a new mail system build out for about 20k email boxes over a few hundred domains. I already run a system like this, but this time I can do it right :). My thought on storage is to have a 12 drive JBOD system attached via SAS to a 3ware 9690SA raid controller. Drives would be RAID'd (10 or 5) to appear as one for message storage. Dovecot would run on that box and deliver directly from postfix. POP and IMAP connections would come in directly (no proxy). Postfix head boxes in front of this do anti-virus and spamassassin, so this box won't be doing any heavy crunching, just delivery and serving of messages. Does this sound reasonable? Is there details that I'm missing? An obvious bottleneck I'm overlooking? Is anyone running a similar config with success? It all sounds very standard, but I haven't run something like this before. Thanks for the help! David

[Dovecot] Moving mail between folders
by Ilo Lorusso 13 Nov '08

13 Nov '08

Hi, Ive just installed Dovecot and postfix and Ive created a whole bunch of folders and started moving my mail around. Ive noticed that it copies the mail to the folder I wish to move the mail to and leave the original message waiting to be purged in the original folder Is there a way to have dovecot delete it straight after it has been moved? as I don't think users are going to take well to this change? any help would be appreciated Thanks, Ilo.

[Dovecot] dovecot pop3 performance, what size installation
by Brandon Lamb 13 Nov '08

13 Nov '08

Hello, I was wondering if anyone could tell me their results and maybe help me get an idea how big our mail system installation and usage is. For dovecot pop3 and nfs backend, I am curious how many machines I should expect to need. Here are my stats for what I can tell. 5-7 connections per second average, 8-12 connections per second peak. 30-50 constant connections between 3 servers (8-20+) on each server. We are servicing about 14,000+ email accounts. These are just the pop3 login stats, a lot of users use both or imap through our webmail. My question I guess is whether this is on the small side, medium or larger side mail setup, and should I be thinking that only 1 or 2 servers should be able to handle the load. Right now I am splitting it between 3. Should a single quad core box be able to handle this? Not sure if this is a simple question or not. Im not including my dovecot -n just because this is more of a generic question.

[Dovecot] removing uid, index and cache files
by Lars Uhlmann 13 Nov '08

13 Nov '08

Since a couple of days we're facing a problem with dovecot/MUA and multiple appeareances of single mails. The mail is physical existant only once but outlook shows it twice or more times. Then after some minutes these multiple "virtual" mails just disappear. Because this happens with different MUAs (Outlook and Thunderbid) I assume dovecot causes the problem. All mail are received by »getmail« from outside via POP3 and delivered to the users local Maildir. This was working without problems for over a year now. Is it save to remove to following files (will dovecot rebuild them) from every users Maildir? dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.log.2 dovecot-uidlist Thahks in advance, Lars

[Dovecot] Sieve authentication / directory issue after upgrade to 1.0.13.
by Drew Calcott 12 Nov '08

12 Nov '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I have come across a problem after upgrading from 1.0.rc17 to 1.0.13 (debian builds 1.0.13 is from etch-backports). I initially upgraded as 1.0.rc17 isn't compiled with regex support, so vacation messages that were uploaded via horde were being rejected. (Everything else was working fine, just messages that required regex functions were failing). Horde is uploading the filters via pysieved, which is then in turn placing them in the directory of: - --------- /shared/spool/active/%d/%0.1u/%1.1u/%n/sieve/ingo - --------- At least, it was previously. Since upgrading, dovecot has changed the way it passes authentication details to pysieved and the domain is no longer included in the username, so the domain cannot be parsed and pysieved fails as it is unable to strip a value for %d. (as a quick aside, this isn't an issue with single domain servers as there is a "defaultdomain" option that will force the value for %d, however, since we have 9 domains to deal with, this isn't going to cut it). Prior to upgrade, authentication was passed as thus (= are a new line in case the formatting dies) - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ====== < OK\t1\tuser=acal030(a)sit.auckland.ac.nz\tuser=acal030\t\n' ===== Finished SASL authentication : {'username':'acal030(a)sit.auckland.ac.nz', 'result': 'OK'} ===== Plugin returned home :'/shared/spool/active/sit.auckland.ac.nz/a/c/acal030/' = Authenticated user acal030(a)sit.auckland.ac.nz - -------- Both user and user@domain were being passed and it was a matter of simple nagging of the pysieved guys to update their code to strip the required information. However, the new version is passing auth like this: - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ======= < 'OK\t1\tuser=acal030\n' ===== Finished SASL authentication : {'username': 'acal030', 'result': 'OK'} ===== Plugin returned home : '/shared/spool/active//a/c/acal030/' - ------- The only change to the dovecot config I have made is to add "allow_all_users=yes" to userdb static as the new version was a lot stricter about the passdb pam lookup not containing the user data (and failing completely as a result). In the dovecot logs themselves, the following lines were from the earlier build: - ------ Info: auth(default): client out: OK 1 user=acal030(a)sit.auckland.ac.nz user=acal030 Info: auth(default): master in: REQUEST 243 23994 1 Info: auth(default): master out: USER 243 acal030(a)sit.auckland.ac.nz home=/blah, mail=/blah etc. - ------ Compared to this from the new one: - ------ Info: auth(default): auth(acal030(a)sit.auckland.ac.nz,130.216.39.182): username changed acal030(a)sit.auckland.ac.nz -> acal030 Info: auth(default): client out: OK 1 user=acal030 Info: auth(default): prefetch(acal030,130.216.39.182): success Info: auth(default): master out: USER 2 acal030 home=/blah, mail=/blah etc. - ------ I am rather at the end of my tether with this, unfortunately. :( I have browsed through many wiki pages looking for a possible solution or config variable I may have missed, but I really am coming up dry. Cleaned up dovecot.conf is at: http://pastebin.com/m7f4303af Should anyone want strace logs or whatever, I'm more than happy to make with them. Thanks in advance for any assistance.

[Dovecot] Dovecot master process
by Steven F Siirila 12 Nov '08

12 Nov '08

We are running into a situation where Dovecot master is simply trying to do too much. It some situations, we are finding that there are times in which it cannot service requests. Restarting Dovecot seems to help in these situations, possibly due to the fact that it no longer has to manage its THOUSANDS of file descriptors for pipes to the many imap/proxy processes that it uses for logging. Is there a way to turn off logging through the master process (in exchange for lesser security)? If not, would it be easy to have the master process do its logging using separate threads (which would help on some modern hardware)? Finally, would it be easy to delegate the task of logging to a dedicated process? We are still running Dovecot 1.0.0 at this time, on Solaris 10 servers. -- Steven F.

[Dovecot] dovecot-antispam crm114 config
by Peter Fern 11 Nov '08

11 Nov '08

Hi list, Does anyone have a working crm114 config for dovecot-antispam? I have mailreaver running perfectly otherwise, but it doesn't seem to be called correctly from dovecot-antispam - the css files show no change. Piping a message to the command... `/usr/share/crm114/mailreaver.crm --good -u /shared/domains/domain.tld/users/pfern/.crm/` works as expected, and the logs don't indicate anything useful that I can see as to why it isn't working from dovecot.

[Dovecot] How to specify /var/spool/mail/m/i/mike
by Network Operations 11 Nov '08

11 Nov '08

I was wondering if somebody could tell me how I can tell dovecot (IMAP) to read users' mail boxes at /var/spool/mail/{1st char}/{2nd char}/username . For example: Mailbox for user 'mike' would be located at /var/spool/mail/m/i/mike 'karen' would be at /var/spool/mail/k/a/karen etc... Is this possible is version 1.1.6? Please advise. Thanks JB

Thanks for > testing! It solves the problem here as well =) Thanks for the update. Do you plan to implement 'out of band' dspam calling? BTW maybe there is no need for a separate 'queue' folder especially as we only need a message signature. I think it can be stored in some buffer array so as the dspam calls are made i.e. during idle time (or during final cleanup at the latest). Also I am attaching a couple of patches that might be useful. dspam-exec.c.patch adds debug-dumping of the dspam reply (it turned out quite useful not only for the stack corruption problem). Makefile.patch fixes the syntax to compile with gmake under FreeBSD 6.1 and also adjusts the installed plugin permissions. Best wishes Eugene

[Dovecot] NFS Unbreakable lock issues
by Rod Treweek 11 Nov '08

11 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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 login_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.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 plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by Stephan Bosch 11 Nov '08

11 Nov '08

Hello Dovecot users, Finally, after little more than a year, I finished the first release of the new Sieve implementation for Dovecot. The main reason for rewriting the Sieve engine is to provide more reliable script execution and to provide better error messages to users and system administrators. Also, since the Sieve language evolves quickly, with new language extensions published every year, the aim is to provide support for quickly extending the engine with new features. This implementation aims to comply to RFC8225 and it provides support for the following Sieve language extensions: * fileinto * reject * envelope * encoded-character * vacation * subaddress * relational * regex * imap4flags * copy * include * body * variables In comparison to the old CMU Sieve plugin, I added support for the very useful variables extension. However, the notify extension is notably missing. This will be implemented for next major release (0.2.x). Refer to the README file for a full list of its features: http://hg.rename-it.nl/dovecot-libsieve/raw-file/0.1.0/README Installation ------------ The source package is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz.sig Alternatively, it can be cloned from the mercurial repository: hg clone http://hg.rename-it.nl/dovecot-libsieve The compilation procedure is identical to the cmusieve plugin (http://wiki.dovecot.org/LDA/Sieve) Don't forget to execute ./autogen.sh first if you obtained the sources through mercurial. This release will not compile against Dovecot versions older than v1.2.alpha3. The configuration is very similar to the original plugin as well. The most notable difference is the name of the plugin, which is simply 'sieve' in stead of 'cmusieve'. After compilation, the Sieve engine can be verified before deployment using the included test suite. This is done by executing `make test` in the top of the source tree. The test suite is known to finish flawlessly on the i386 and amd64 platforms. The test suite is not very comprehensive yet, as it only tests the evaluation of scripts and omits testing the actual execution of actions. As this release contains about 30k effective lines of fresh code, bugs will eventually surface. Make sure that you provide enough information to reproduce the problem if you report bugs, i.e. the script and the mail message that caused the problem and/or relevant log entries. Have fun testing the new Sieve plugin. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] antispam plugin claims "antispam signature not found"
by Jakob Curdes 09 Nov '08

09 Nov '08

Hi, I am trying to setup the antispam plugin using the direct dspam backend. I have set antispam_signature = X-DSPAM-Signature in dovecot.conf and in all mails I have signature lines like X-DSPAM-Signature: 1,49084a24139132188715614 but still, if I try to move a mail into the spam folder, i get the IMAP error message "antispam signature not found". I thought it might have to do with permissions and made sure that the user running dovecot is able to execute the dspam binary. I also tried to enable debug logging to syslog (via the .config file in the make process) but I do not see any debug messages showing up; where should these go? to the mail facility? Perhaps somebody who has a working setup can shed some light on this? Yours, JC

[Dovecot] Renames across namespaces
by Ben Winslow 07 Nov '08

07 Nov '08

Will Dovecot ever support renames across namespaces? I'm attempting to support mailboxes under "INBOX" for compatibility with Courier, which I'm trying to replace, while also supporting mailboxes with no prefix. I don't want to confuse new users (who aren't already subscribed to their mailboxes with the INBOX prefix) by listing the entire tree twice (parented at the root and at INBOX.) This configuration seems to provide what I want: mail_location: maildir:~/mail namespace: type: private separator: . prefix: INBOX. inbox: yes hidden: yes namespace: type: private separator: . list: yes subscriptions: yes ...except that, when a legacy user tries to delete a mailbox under INBOX, Thunderbird (at least) renames the mailbox to make it a child of Trash at the root, e.g.: tag123 RENAME "INBOX.test" "Trash.test" tag123 NO Can't rename mailbox to another storage type. I was a little surprised that it didn't work at first, since they're both using the same (default) mail_location, but I see why it doesn't work after looking at the code. Is there any chance cross-namespace (and even cross-storage _type_) wouldn't eventually be supported? (I guess that the big problem is making cross-type renames appear atomic to clients.) Is there a better way to do what I'm trying to do? -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] Fetch order
by Warren Baker 07 Nov '08

07 Nov '08

Hi all, Is there a function to modify the fetch order of messages? We have just migrated from Courier to Dovecot and I notice that there is a slight difference in the way messages are fetched in Dovecot compared to Courier. Both Courier and Dovecot sort the mailbox correctly (UID SORT (REVERSE ARRIVAL) UTF-8 ALL), for example: [ 13:22:02.790 ]50800314 UID SORT (REVERSE ARRIVAL) UTF-8 ALL * SORT 195 194 193 192 191 190 189 188 187 186 185 184 183 182 181 180 179 178 177 176 175 174 173 172 171 170 169 168 167 166 165 164 163 162 161 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 43 44 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 1 4 8 10 15 18 20 25 14 19 2 3 5 9 13 17 21 22 7 11 16 6 12 23 24 50800314 OK Sort completed. But if we fetch the latest 25 messages, Dovecot will fetch the lowest UID in the list first, so from the example above it would fetch UID 171,172,173 and so on. Courier on the other hand would start the fetch on UID 195,194,193 and so on. We have an internal developed webmail application that has been affected by this change, so I am just wondering whether there is a interim fix while we fix our webmail application to cater for this. Thanks, Warren

[Dovecot] index storage usage
by Giorgenes Gelatti 07 Nov '08

07 Nov '08

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg

[Dovecot] (1.0.13) fsync failed: Disk quota exceeded for some accounts
by Eric Marin 07 Nov '08

07 Nov '08

Hello all, We've recently migrated the mail server used by our 5000 students, from Tru64/UW-IMAP/Procmail/Postfix/mbox to Debian Etch/Dovecot/Deliver/Postfix/Maildir E-mails are not stored directly on the server (except for index and control files), but on an NAS that exports the students' homedirs on NFS. Each student has a 100MB quota on the NAS. Here is the configuration : vega:~# dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 listen: [::] ssl_disable: yes disable_plaintext_auth: no verbose_ssl: yes 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_process_size: 32 login_max_processes_count: 1024 mail_privileged_group: mail mail_location: maildir:~/Maildir:INDEX=/var/mail/index/%u:CONTROL=/var/mail/control/%u maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: 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): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: mail/ hidden: yes auth default: cache_size: 1024 passdb: driver: pam args: blocking=yes cache_key=%u dovecot userdb: driver: passwd args: blocking=yes When one mails a student that has filled his quota, one immediately receives this message : "Your message to <studentx> was automatically rejected: Not enough disk space Reporting-UA: vega; Dovecot Mail Delivery Agent Final-Recipient: rfc822; studentx Original-Message-ID: <490F0A9A.8030109(a)utc.fr> Disposition: automatic-action/MDN-sent-automatically; deleted" And in /var/log/mail.log : (...) save failed to INBOX: Not enough disk space (...)

It gets deferred... I have looked at the changelog for Dovecot, but have not found a clear clue that is a bug (if it is !) that has already been corrected in a more recent version... Though if possible, I'd like to keep the Debian package (from etch-backports) instead of compiling it from source. Also, while I've found Dovecot's wiki to be surprisingly informative, there are still a few points that did not seem very clear : - should I use the quota:fs plugin in this case (it seems to work out well without it for most users) ? - would it work in v1.0.13 on NFS ? - if it worked, and I enabled it, what would change for me ? - what is *supposed* to happen without the quota plugin when a user has filled his quota : mail is rejected, or mail is deferred ? - and what about imap_quota ? Best regards, Eric

[Dovecot] Compiling dovecot 1.1.6 with ICC
by Steve 06 Nov '08

06 Nov '08

Hello list I have compiled PostgreSQL with ICC (Intel C/C++ compiler) and this forces me to compile dovecot 1.1.6 as well with ICC. Trying to compile it with GCC fails, telling me it can not build with PostgreSQL support since it can not find libpq (but libpq is there!). The funny part is that I can compile dovecot 1.1.6 with GCC 4.3.2 against MySQL which is build with ICC. But I can not build against PostgreSQL build with ICC. Why is that? Does any one know the reason why PostgreSQL is treated differently then MySQL in dovecot? Well... so no way to get around to build dovecote with ICC. I can build dovecot with ICC but as soon as I start it, I get a crash. Loading the core dump into GDB does not give me much info. Probably because I have not compiled dovecot with debug symbols. Currently I am doing that. Hopefully this will produce better core dumps. I will post more info as soon as I get them. But in the mean time maybe some one has a hint for me how to get dovecot 1.1.6 to build properly with ICC? // Steve -- GMX Download-Spiele: Preizsturz!

[Dovecot] Strange and sudden deletion of mails messages
by נור דאוד 06 Nov '08

06 Nov '08

Hello everyone, I'm having a bizarre problem (bug?) concerning deletion of messages from one of the mailboxes. The platform is set up as follows: FreeBSD 7-STABLE Postfix 2.6-20080411 Dovecot 1.0.13 Webmail using RoundCube 0.1-STABLE The trace (in Postfox logs) revealed that the message has been actually received, and saved to maildir, and then viewed once in Webmail. Hitting Reply in Webmail produced an error, and the letter (somehow) was nowhere to be found on the server! I have no clue what's the cause of this. Is there a way in Dovecot to catch all commands sent to the server, thus revealing who in effect deleted the message? Thanks in advance. Noor

[Dovecot] feature request for dovecot 1.2 Master users/passwords for virtual domain admins
by Robert Schetterer 06 Nov '08

06 Nov '08

Hi Timo, currently superadmins can be configured in dovecot i.e in mysql as "superadmins" this means the can log in in any mailbox on the server this is a very nice feature in real world scenarios specially for support people in postfixadmin i.e there are also defined domainadmins ( this is for delegate usermail creation/delete etc in the postfixadmingui ) in mysql it would be nice to have or simply use postfixadmins mysql domainadmins in mysql table entries to login for domainadmins only login to mailboxes of their related maildomain this would be also massiv helpfull for postmasters/support people in a full virtual setup perhaps you might get this in dovecot 1.2 before closing at beta stage -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] How do I use plus-addressing in Dovecot 1.1.x?
by Jon Fullmer 06 Nov '08

06 Nov '08

I'm using Postfix, Amavisd-new/SpamAssassin, and Dovecot. They all run on the same server (running Linux). The mailboxes are stored on the same server in maildir format. The logical path for incoming messages (as I understand it) is: 1) received by Postfix; handed off to Amavisd-new 2) Amavisd-new checks to see whether or not it's spam/undesirable; hands off to Dovecot deliver 3) Dovecot deliver delivers the message to the local mailbox Under each of my user's mailbox is a submailbox called "spam". Just so I don't confuse terminologies (I'm no IMAP/maildir expert), for example, we have someone(a)domain.com. My configured mail_location is "maildir:/srv/mail/%d/%n", so this person's mailbox is located here: / srv/mail/domain.com/someone/ Within this directory is another mailbox: /srv/mail/domain.com/someone/.spam/ The plan is to have Dovecot deliver send a message (which has been labeled by Amavisd-new as spam) directly to the ".spam" submailbox, instead of the INBOX (/srv/mail/domain.com/someone/). With Dovecot 1.0.x, I used "plus addressing". Amavisd-new was configured so that, if a message was found to be spam, it delivered the message to Dovecot deliver, but changed the delivery address. Now, instead of "someone(a)domain.com ", it was "someone+spam(a)domain.com". Dovecot deliver took this message and delivered it correctly to the ".spam" submailbox (/srv/mail/ domain.com/someone/.spam/) Just to emphasize, this process does work (using Dovecot 1.0.x). With Dovecot 1.1.0, this process is broken. Now, spam messages are delivered to the INBOX instead, and, when checking the dovecot- deliver.log, I'm seeing "save failed to spam: Unknown namespace". As best as I can tell, the answer seems to lie in "namespaces" as a feature added in Dovecot 1.1.0. The problem is that I don't understand how I could use them to resolve this situation. I've read the documentation. I've looked at as many example configurations as I could find. Please help. I want to get this working again. I'm sure it's something very straight-forward, but I don't understand. How must I change my Dovecot 1.1.x configuration so that my "plus addressing" set up (detailed above) will work again? Or is there a better way? Thanks so much for your help, and thanks for a great product! - Jon

[Dovecot] Limit simultaneous pop3 login for users?
by Patrick MacDonald 05 Nov '08

05 Nov '08

Is there a way to limit simultaneous pop3 logins for users? Like for a user that has pop-every-minute running on two different computers from two different networks? If dovecot can't stop it, anyone know of a trick I could implement? Thanks in advance! Patrick

[Dovecot] mUTF-7 vs UTF-8 in mailbox names
by Timo Sirainen 05 Nov '08

05 Nov '08

(This is about v1.2 only, v1.1 will stay as it is.) Until today Dovecot didn't care about mailbox names. IMAP RFC requires them to be modified-UTF-7, but Dovecot didn't try to enforce it in any way. Mailbox names in Sieve scripts should be UTF-8, but currently Dovecot doesn't translate them to mUTF-7 as it should. Cyrus also did this until the latest release (v2.3.13). Now that I finally today wrote code to do mUTF-7 <-> UTF-8 conversion, Dovecot can finally do the right thing. But should there be an option to keep things backwards compatible? - IMAP: CREATE command requiring the mailbox name to be valid mUTF-7 is probably ok. Several other servers already verify that mailbox names are valid, so I doubt there are clients left anymore that don't send mUTF-7 names. - deliver -m assumes now that the mailbox name is UTF-8 and converts it to UTF-7. Should there be a -7 parameter that changes this behavior back? - Stephan's Dovecot Sieve also needs to be changed so that the mailbox name in fileinto commands can be UTF-8. If -7 parameter is added, it could control this behavior too. Also I'm wondering if in the future the mailbox names in filesystem should be converted to UTF-8. Probably not anytime soon though.. I also added imap_utf7 binary for doing mUTF-7 <-> UTF-8 conversion.

[Dovecot] Another dovecot-antispam plugin can't call dspam
by Rob Klingsten 05 Nov '08

05 Nov '08

Hi folks - I am configuring a new system and the antispam plugin is the last piece I need, everything else is working. Thanks to Johannes for this plugin, it's exactly what I want and an elegant solution for filter training. But I've been trying everything I can think of for the last 3 days to get this to work, no success. I've got: Postfix 2.5.3, dspam 3.8.0, Dovecot 1.1.6, Maildrop 2.0.4 and dovecot-antispam 1.0 tarball. I've built dspam from source with --disable-trusted-user-security to try and isolate the source of the plugin problem, which is the message at the IMAP client "Failed to call dspam." Here's what I've got configured for the plugin: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_spam = SPAM;Spam antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --user %u And here's what happens: Nov 5 09:31:29 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:31:29 venus imap: antispam: "trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:31:29 venus imap: antispam: "SPAM" is spam folder Nov 5 09:31:29 venus imap: antispam: "Spam" is spam folder Nov 5 09:31:29 venus imap: antispam: no unsure folders Nov 5 09:31:29 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:31:29 venus imap: antispam: dspam extra arg --user dump-capability Nov 5 09:31:29 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:31:29 venus dovecot: Dovecot v1.1.6 starting up Nov 5 09:31:29 venus dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (postfix) Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=686 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=687 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxxx rip=xxxx lport=143 rport=55904 Nov 5 09:32:45 venus dovecot: auth(default): client out: CONT 1 Nov 5 09:32:45 venus dovecot: auth(default): client in: CONT<hidden> Nov 5 09:32:45 venus dovecot: auth-worker(default): sql(rob(a)xxxx.org,xxxx): query: SELECT password, email AS user FROM users WHERE email = 'rob(a)xxxx.org'; Nov 5 09:32:45 venus dovecot: auth(default): client out: OK 1 user=rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: auth(default): master in: REQUEST 1 688 1 Nov 5 09:32:45 venus dovecot: auth(default): master out: USER 1 rob(a)xxxx.org uid=5000 gid=5000 home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: imap-login: Login: user=<rob(a)xxxx.org>, method=PLAIN, rip=xxxx, lip=xxxx Nov 5 09:32:45 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Loading modules from directory: /usr/lib/dovecot/imap Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Module loaded: /usr/lib/dovecot/imap/lib90_antispam_plugin.so Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Effective uid=5000, gid=5000, home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:32:45 venus imap: antispam: "trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:32:45 venus imap: antispam: "SPAM" is spam folder Nov 5 09:32:45 venus imap: antispam: "Spam" is spam folder Nov 5 09:32:45 venus imap: antispam: no unsure folders Nov 5 09:32:45 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:32:45 venus imap: antispam: dspam extra arg --user rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir: data=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir++: root=/var/mail/xxxx.org/rob, index=, control=, inbox=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: from trash: 0, to trash: 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(Spam): 1 Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Can anyone give me some more suggestions? thanks!

[Dovecot] MasterUser and old rev of Dovecot (0.99.14)
by Christopher Alexander 04 Nov '08

04 Nov '08

I need to migrate an old mail server running Dovecot (0.99.14) to a new server running Dovecot (1.0.7; as shipped with CentOS 5.2). My plan was to use the imapsync utility as this will "seamlessly" do the conversion from mbox to maildir between the boxes as well. I've got the MasterUser authentication working fine on the new host and was just about to start getting MasterUsers working on the old host. I noticed that the old .99 version dovecot.conf seems to have a mildly different syntax from 1.0 dovecot.conf. In particular a lot of the directives do not use braces and such. Is the .99 dovecot.conf file essentially able to deal with the same sort of syntax as outlined in the MasterUsers wiki page? [ http://wiki.dovecot.org/Authentication/MasterUsers ] I just wanted to bounce this off you guys before I started messing with a live system. ;) Thanks in advance. -- Christopher Alexander UNIX Network Administrator Broadband Network Technologies Branch (VPNT), Research Network Systems (MRNS) Communications Research Centre [ http://www.crc.ca ] Government of Canada [ http://www.gc.ca ]

It's not clear from your response that you understand why it's failing. It would seem clear that postfix doesn't see this as a local domain. Instead, it thinks you're trying to relay to somewhere else. Check your virtual_mailbox_domains file (or database) and make sure it has an entry for the new domain.

[Dovecot] v1.2.alpha1 released
by Timo Sirainen 02 Nov '08

02 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz.sig This is the only v1.2.alpha announcement I'm going to send to dovecot-news list. Next announcement will be for either v1.2.beta1 or v1.2.rc1. I'm hoping that v1.2 stabilizes pretty soon. There are no huge changes like there were in 0.99->1.0 or 1.0->1.1, so most of the bugs are probably related to new features. I'm already running v1.2 myself and it's gone through heavy stress testing with my imaptest tool, so I'm expecting it to be stable enough for real world testing with not-all-that-important servers. It's safe to jump between v1.1 and v1.2 at any time or even have them concurrently accessing the same mailboxes. Dovecot v1.2 has a lot of new IMAP extensions implemented. The biggest change comes from CONDSTORE extension which adds a new concept of "modification sequences" (modseq for short). Each message has a modseq that increases whenever a flag is changed or when the message is expunged. The client can keep track of the highest seen modseq and request only changes done since the modseq. See QRESYNC (RFC 5162) for more information. Dovecot starts keeping track of the modseqs only when the first "CONDSTORE/QRESYNC enabling command" is executed. Before that no disk space is used for modseqs. When modseqs are enabled dovecot.index file uses 8 bytes per message more space. Other implemented IMAP extensions are: ESEARCH, SEARCHRES, WITHIN, ID and CONTEXT=SEARCH. Added thread indexes to optimize IMAP THREAD command. Only the first half of threading is currently optimized, the rest will hopefully follow later. Added a non-standard X-REFERENCES2 threading algorithm where threads are sorted by their latest message instead of the thread root message. There is also no base subject merging. This may be renamed and become part of SEARCH=INTHREAD extension some day. SEARCH=INTHREAD is still a draft, but the INTHREAD search key is already implemented by Dovecot v1.2. This is mostly useful with virtual mailboxes. Virtual mailboxes: http://wiki.dovecot.org/Plugins/Virtual Then there are also some internal API changes which will make some things easier. For example lib-storage now allows handling multiple different users at the same time.

[Dovecot] pam_dovecotpw anybody?
by Steinar Bang 02 Nov '08

02 Nov '08

Samba has pam_smbpass which is a PAM module that hooks into password changing, and changes the users' samba password (presumably used for NTLM auth?), when the users change their ordinary unix/linux password. http://gitweb.samba.org/?p=samba.git;a=tree;f=source3/pam_smbpass;h=c230a1b… It shouldn't bee too hard to take the code from here, combine it with dovecotpw and create a PAM module that changes the dovecot password in a way that can be used for cram-md5. Ideally it should read the /etc/dovecot/dovecot.conf (whereever it is), and find the path of the passwd-file and use that. Has anyone else looked into doing something like this?

[Dovecot] Backing Up
by Neil 02 Nov '08

What is the best way to do a (server-side) backup of all mail in a user's mail? I don't think I'm doing anything weird as far as configs go; here's dovecot -n if it helps: # 1.1.4: /etc/dovecot/dovecot.conf protocols: imaps listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/cert.pem ssl_key_file: /etc/ssl/dovecot/key.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/.maildir auth default: mechanisms: plain login passdb: driver: pam args: * userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] feature request for managesieve build from packager
by seriv＠parkheights.dyndns.org 02 Nov '08

02 Nov '08

Hi everybody, dovecot-1.2 alpha3 with cmusieve, libsieve and managesieve are available as rpm packages for Sisyphus repository (http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus, and specs/patches are available at http://git.altlinux.org/people/seriv/packages/?p=dovecot.git and http://git.altlinux.org/people/seriv/packages/?p=dovecot-sieve.git) Thank you very much Timo and Stephan! I have a feature-request for managesieve configure and Makefiles: they depend on dovecot sources as they are used for build process. I think it would be very nice to have not just --with-dovecot parameter in configure parameters, but also --with-dovecot-includes and --with-dovecot-libs. The same about cmusieve plugin: dovecot has --enable-header-install parameter, but installed headers are not sufficient for building cmusieve, I need install libraries and then modify cmusieve's Makefiles by running something like: --- for f in `find . -name Makefile` do mv -f $f $f.orig sed -e's/\$(dovecotdir)\/src$\/lib\/.*\.a$/\$(libdir)\/dovecot\/modules\1/g' \ < $f.orig > $f done --- before make in %build section. -- With best regards, Sergey Ivanov.

[Dovecot] imap processes eating IO
by Ryan Rawdon 02 Nov '08

02 Nov '08

[Ignore the previous e-mail, I somehow sent it when I was trying to paste from clipboard] I recently migrated my dovecot/postfix setup to a new machine. After doing so, I have encountered a problem where imap processes get stuck in a loop eating loads of IO on the machine. Looking at the trace (snippet below), it looks like they are sitting and reading the inbox and other folders of certain users repeatedly. This seems to be triggered by the delivery of a new e-mail to the user's mailbox while they have an IMAP client connected, though I cannot say for sure. This had never happened before on the old machine. I'm certain more information would be useful, please let me know what I can provide to help! Trace of process 22342 - imap lstat64("/home/vmail/u13.net/ryan/Maildir/cur/1203440140.P6242Q0M41485.scarecrow:2,RSc", {st_mode=S_IFREG|0600, st_size=3079, ...}) = 0

[Dovecot] antispam plugin problem
by Eugene 01 Nov '08

01 Nov '08

Hi people! (Especially Johannes, probably =) I recently switched to DSPAM + antispam plugin combination. Mostly I am happy but there is a problem with calling dspam-exec in order to relearn the messages. Moving messages to spam folder does not work, giving the error message 'Failed to call dspam' to client. I tried to add some debug output and here are the results: This is the output of debug("calling dspam: %s %s %s %s %s %s %s", argv[0], argv[1], argv[2], argv[3], argv[4], argv[5], argv[6]); (debugv(argv) does not produce any output for some reason) Oct 26 02:37:12 qqqqq imap: antispam: calling dspam: /usr/contrib/bin/dspam --source=error --class=spam --signature=490387db858421194018847 --user genie (null) This is the captured output of forked process Oct 26 02:37:12 qsar imap: antispam: dspam returned: ^APdata stack: Out of memory when allocating 1073741840 bytes If I understand correctly, this message is produced by dovecot before it should have launched dspam executable. I don't know why it needs 1GB of stack space for that. Changing dspam to dspamc does not help. Interestingly enough, launching 'sendmail' in mailtrain mode works ok. Do you have any ideas about what is wrong? Best wishes Eugene

[Dovecot] Dovecot+PostfixAdmin+PostgreSQL on FreeBSD 7

Hi dear All, Currently I'm configuring Dovecot+PostfixAdmin+PostgreSQL on FreeBSD 7 Stable and using Dovecot v1.1.3. I hope I've configured everything. But when I run /usr/local/etc/rc.d/dovecot start then dovecot doesn't seems to running. /var/log/maillog is only showing following.

[Dovecot] dovecot expire doesn't work (?)
by LÉVAI Dániel 31 Oct '08

31 Oct '08

Hi! I'm using dovecot-1.1.5 and trying to make the expire plugin work. What I've configured in dovecot.conf is the following: protocol imap,pop3,lda { mail_plugins = [...] expire } dict { expire = db:/var/dovecot/expire/expire.db } plugin { expire = spamassassin/SPAM 2 spamassassin/HAM 2 expire_dict = proxy::expire } I have a sieve rule, to copy certain messages to my "spamassassin/SPAM" folder. Then I want to expire those messages after 2 days (I think I've configured that under the plugin{} section in dovecot.conf). So the actual message saving is done by the dovecot's deliver, but I have the plugin loaded under the "protocol lda {}" section too. So I thought now I just have to wait 2 days, and run the expire-tool, and then it will expire the messages. Now I have three messages dated back to 10.25, but running the expire-tool outputs nothing. # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Nothing in the logfiles, and nothing on the console. I have the /var/dovecot/expire directory: # ls -la /var/dovecot/expire/ total 1640 drwx------ 2 root wheel 512 Oct 26 19:47:53 2008 ./ drwxr-x--- 3 root wheel 512 Oct 27 07:57:42 2008 ../ -rw------- 1 root wheel 24576 Oct 27 13:00:01 2008 __db.001 -rw------- 1 root wheel 57344 Oct 27 13:00:01 2008 __db.002 -rw------- 1 root wheel 270336 Oct 27 13:00:01 2008 __db.003 -rw------- 1 root wheel 98304 Oct 27 13:00:01 2008 __db.004 -rw------- 1 root wheel 49152 Oct 27 13:00:01 2008 __db.005 -rw------- 1 root wheel 32768 Oct 26 19:47:37 2008 expire.db -rw------- 1 root wheel 10485760 Oct 27 14:22:08 2008 log.0000000001 It contains the familiar BDB files, so I think it works, although the expire.db's modify time is yesterday, but deliver saved some messages also today to the spamassassin/SPAM folder. What could be the problem? Am I missing something? Thanks! Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Problem with Dovecot 1.1.4 and dovecot-antispam 20080829
by Guillaume Hilt 31 Oct '08

31 Oct '08

Hi there, I'm running a server under Gentoo 64 with postfix 2.5.5, Dovecot 1.1.4-r1 and Dovecot-antispam 20080829 (all are the lastest versions availables under Portage). I ran into a problem when I log in to my mailbox : Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Loading modules from directory: /usr/lib64/dovecot/imap Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Module is for different version 1.1.1: /usr/lib64/dovecot/imap/lib90_antispam_plugin.so Oct 30 10:39:23 ks29138 dovecot: Fatal: IMAP(hiltg): Couldn't load required plugins Is there another version for Dovecot 1.1.4 out there or must I go back to 1.1.1 ? Thanks, Guillaume

[Dovecot] Dovecot read only for users
by JC 31 Oct '08

31 Oct '08

All, I have hopefully a base question. How do you give users only read access to their inbox and folders? If I use chmod 600 they have full access. If I do a 400 they have read access but cannot access their inbox. The config file is the out of the box config other than advertising IMAP and IMAPS. Any help will be appreciated. Thanks.

[Dovecot] Startup info message
by Athan Dimoy 30 Oct '08

30 Oct '08

Hi folks, I'm using the latest Dovecot 1.16 with Postfix for my FreeBSD box. Since v1.1.4 (if i remember correctly), the following message is displayed whenever starting Dovecot. "Info: If you have trouble with authentication failures, enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork" Besides that, Dovecot works great but I wonder what this message is all about. I've searched wiki and mailing list but didn't find anything related. PS: I removed Dovecot removing all stalled files and directories and reinstalled it from scratch. Still the message is displayed whenever it starts. Any idea? Athan

[Dovecot] SIGBART/SIGSEGV while SELECTing virtual folder
by Lars Noschinski 30 Oct '08

30 Oct '08

Hello! I just installed Dovecot's latest nightly build (20081020) and tried the virtual folder features. I started with a really simple "all" folder: | # virtual/all | * | all But selecting this folder causes dovecot to panic (in most cases). While trying to debug this, I got slightly different results and I am not really sure yet if this is just non-deterministic, depends on some cached dovecot data or if there is some difference between the debug build or my rudimentary, unpatched debian package (which lacks the debug symbols). The results below are from a build with --prefix set to a clean, temporary directory. Similar problems occured also with the alpha2 release, which caused me to try the latest nightly build. --------------------------------------------------------------------- % ./sbin/dovecot --exec-mail ext /usr/bin/gdb ./libexec/dovecot/imap GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Dovecot] dovecot 1.1.5 mbox bug (From_-line separator related)
by Anton Yuzhaninov 30 Oct '08

[Dovecot] mail_executable's process environment
by Mike Malsman 30 Oct '08

30 Oct '08

Hello, I recently had to get Dovecot 1.1.4 to write to a "pop3/imap-before- smtp" db such that my MTA could permit relay after a successful authentication with Dovecot. The 'pop3' and 'imap' processes are executed only after a successful auth, so replacing them with wrappers which write to the db seemed the natural choice. Lo and behold, someone thought of something like this, as the 'mail_executable' directive exists - neat. Upon inspection of the processes' environment I'm pleased to see that there's a load of useful information in there. However, one essential component in my case is the destination network address, which is missing. I added it with the attached patch, exposed as 'LOCAL_IP'. Works for me. Is this something that would be useful to anyone else? -Mike

[Dovecot] [dovecot] Enable logging of all client commands in dovecot-1.2.alpha3
by Jonathan Siegle 30 Oct '08

30 Oct '08

Hello, I would like to log all IMAP client commands sent to dovecot. The format would be time pid command arguments. I reviewed http://wiki.dovecot.org/Logging and started digging through dovecot-1.2.alpha3/src/master . I don't need this turned on all the time, just enough to see how clients do things and I don't need to see passwords. Any tips would be appreciated. -Jonathan

[Dovecot] benchmark dovecot
by Mathieu Kretchner 30 Oct '08

30 Oct '08

Hello, We would like to do a feed back to this active mailing list. We are working on a migration project from cyrus to dovecot. And we have just completed the benchmark sequence. As I say, this benchmark is here only to show that our old imap server is out to date. I would not be the source of controversy at all, so I try to explain my approach. Because the only thing I found was this old oriented benchmark : http://www.isode.com/whitepapers/mbox-benchmark.html We've tried to do our tests, here you could find our results : http://www-sop.inria.fr/members/Mathieu.Kretchner/dotclear/index.php/2008/1…

[Dovecot] Enh-Req: Mark As Read When Delivered
by Neil 30 Oct '08

30 Oct '08

I'm under the impression bug-reports are supposed to go to the list, so hopefully it's okay if I put in a feature request here too (assuming it's not already implemented; but it doesn't look like it). Basically, all I would like to do is be able to sometimes deliver mail as already mail into mail boxes. Is there some way to do this? If not, could a flag perhaps be added to deliver to do it? (And Sieve; but for now I think procmail still has much higher adoption, and thus having it in deliver would be rather key...) Thanks, -Neil.

[Dovecot] INBOX stored in AFS
by Hans-Werner Paulsen 30 Oct '08

30 Oct '08

Hello, currently we are storing the incoming mail in the user's home directory, which is within a distributed filesystem called AFS (OpenAFS). Accessing the "mbox" file directly (using the distributed filesystem) works fine with mutt, thunderbird, ... To access the INBOX from a machine, which does not have access to this distributed filesystem, we are using IMAP (UW-imap). Now I wanted to check if dovecot can do the job (maybe faster than UW), and I had the following problem: This is my configuration: ------------------------------------------------------------------------------- # 1.1.4: /opt/dovecot-1.1.4/etc/dovecot.conf log_path: /var/log/dovecot ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/keys/imapd.pem login_dir: /var/run/dovecot/login login_executable: /opt/dovecot-1.1.4/libexec/dovecot/imap-login first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=~/.maildir/incoming mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl mbox_dirty_syncs: no mbox_lazy_writes: no mail_executable: /opt/dovecot-1.1.4/libexec/dovecot/afs-token /opt/dovecot-1.1.4/libexec/dovecot/imap auth default: verbose: yes debug: yes passdb: driver: pam args: setcred=yes session=yes dovecot userdb: driver: passwd ------------------------------------------------------------------------------- When I start my imap-client, I see the content of the INBOX, and I can read, delete, ... the different entries. But when new mail arrives dovecot (and my imap-client) will never notice this. And when I quit my imap-client the dovecot imap server will write back its view of the INBOX, and delete this new mail. This seems to be a problem related to AFS. I poked in the dovecot code and have the following theory: dovecot opens the INBOX R/W, dovecot calls "stat" on the INBOX file periodically to look for modifications. But this does not work, because this machine will stat the local copy (AFS cache) of the INBOX as long as this file is still open R/W. My questions: Is it possible to have a configuration, that the INBOX file is not left open when stat-ing this file? Or is it possible to open the INBOX file R/W only when it us locked? Or is it necessary to modify the code?

Re: [Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by seriv＠parkheights.dyndns.org 30 Oct '08

30 Oct '08

Thank you Timo, it was my mistake. In 'plugin {}' section line 'sieve = /var/sievescripts/%n/sieve' worked for both cmusieve and sieve plugins. Command 'fileinto "INBOX/foo/bar"' with private namespace configuration you proposed - also worked in both plugins. I suspected that they have different behavior: cmusieve saved message into INBOX/foo/bar, while sieve - into foo/bar as in the deliver log I'm pasting here. But both messages were filed into the same mail folder. Difference in the logging, I think, is not a big problem. --- ls -l Maildir/.foo.bar/new total 8 -rw------- 1 seriv seriv 513 Oct 30 01:57 1225331850.M790093P1351.sisyphus.office.omniti.com,W=526 -rw------- 1 seriv seriv 518 Oct 30 01:59 1225331966.M468658P1400.sisyphus.office.omniti.com,W=531 tail -n 18 /var/log/deliver/dovecot-deliver.log --- deliver(seriv): Oct 30 01:57:30 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:57:30 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_cmusieve_plugin.so deliver(seriv): Oct 30 01:57:30 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:57:30 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:57:30 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Executing script /var/sieve-scripts/seriv.sievec deliver(seriv): Oct 30 01:57:30 Info: Namespace INBOX/: Using permissions from /home/seriv/Maildir: mode=0644 gid=-1 deliver(seriv): Oct 30 01:57:30 Info: msgid=<20081030015649.B7936140A88(a)sisyphus.office.omniti.com>: saved mail to INBOX/foo/bar deliver(seriv): Oct 30 01:59:26 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:59:26 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_sieve_plugin.so deliver(seriv): Oct 30 01:59:26 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:59:26 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:59:26 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:59:26 Info: sieve: using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: opening script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: executing compiled script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: msgid=<20081030015911.576FC140A88(a)sisyphus.office.omniti.com>: stored mail into mailbox 'foo/bar' -- WBR, Sergey Ivanov. ----- "Timo Sirainen" <tss(a)iki.fi> wrote: > On Wed, 2008-10-29 at 20:31 +0100, Stephan Bosch wrote: > > sergey ivanov schreef: > > > Hi Stephan, > > > Thank you for quick fix.

Did you try dovecot-sieve-1.1 with dovecot 1.2 to verify? I'll ask Timo about this. What is the configuration of your mail store.

[Dovecot] FTS index generation
by Dave McGuire 29 Oct '08

29 Oct '08

Hi folks. I'm experimenting with the Squat plugin. I can execute search commands via direct interaction with IMAP, but I never see the expected dovecot.index.search index file appear in the spool. I'm concerned that I've misconfigured something that is preventing the creation of those indices. Is there a facility to have the squat plugin generate debugging messages so I can see what it's doing? Thanks, -Dave -- Dave McGuire Ahh, you voted for Bush? Port Charlotte, FL Happy now?

[Dovecot] Embedded "From<space>" Lines
by Lennart Lövstrand 29 Oct '08

29 Oct '08

Hi. As some of you may remember, I reported a problem a while back where dovecot 1.1.beta14 (as well as dovecot 1.0) would corrupt mbox-style mailboxes by ignoring the Content-Length header and breaking up messages with embededed "From<space>" lines. I recently downloaded Dovecot 1.1.5 and noted to my pleasure that this bug now has been fixed. That's great! This fix envolves checking to see if the expected_body_size (from the Content-Length header) is larger than the body_size produced by the "From<space>" scanner, and if so, if there is a valid "From<space>" line at the "expected" end of the message. However, I also noted that there's a case which the fix doesn't cover, and that's where the "From<space>" line appears as the first line of the body of the message. When this happens, the body_offset will point to the blank line between the headers and the body and not the actual first line of the body. This will cause the stream to be mispositioned at the time of the "From<space>" verification check in istream_raw_mbox_get_body_size and the (actually correct) expected_body_size will be rejected. I have enclosed a simple diff that will work around this by adjusting the body_offset to point to the next line at the time of call to istream_raw_mbox_is_valid_from in istream_raw_mbox_get_body_size. This appears to handle the problem correctly in all the test cases I have. To anyone else who has run into this problem and gotten corrupted mailboxes as a result, I can also offer an mbox checker that will attempt to detect and repair this problem in existing mailboxes as well as inspect them for other problems. I'm not ready to send it out for a full release yet, but interested beta testers are invited to contact me directly. Cheers, --Lennart

Now i am setting up the quota warning, with this in dovecot.conf: quota_warning = storage=70%% /usr/bin/quota_warning.sh 70 In the plugin section naturally. All seems to work fine, the quota is calculated right, but seems the script is not executed... In dovecot logs i have this: deliver(test(a)test.com): Oct 27 15:14:53 Info: Quota warning: bytes=10752000 (70%) messages=0 (0%) command=/usr/bin/quota_warning.sh 70 But...nothing happens. My quota_warning.sh is this: #!/bin/bash PERCENT=$1 echo "/usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf" > /var/log/quotanotify cat << EOF | /usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf From: postmaster(a)mediaservice.net Subject: quota warning Your mailbox is now $PERCENT% full. EOF I have added the echo for debug pourpose, but no file was created, so the script is not executed. I thinked is a permission problem, but seems not. Now the script is like this: -rwx--x--x 1 dovecot dovecot 317 Oct 27 15:30 /usr/bin/quota_warning.sh What can be the problem? Stuck!!!

[Dovecot] Dovecot pop3 and SonicWall?
by Brandon Lamb 29 Oct '08

29 Oct '08

Hello Has anyone else run into a problem with dovecot pop3 and sonicwall? A week after switching to dovecot we had two local customers call and report they could no longer download emails with attachments. It turned out to be the email macro filter on the router. After the first report I thought maybe the customer had just changed something or it was a fluke, but then a day later we had the second call with the same issue. For some reason, after us switching the sonicwall's email macro filter was catching any attachments as a threat. I couldnt see how changing pop3 servers could affect that, but I guess anything is possible. I just emailed sonicwall and am waiting for a response from them now as well. Hopefully maybe someone has heard of this before. Unfortunately, I dont know if this was pure coincidence, or if both customers happened to have updated their sonicwall software, or maybe it autoupdates, I have no information on it.Of course to them it looks like we broke it. We just had them both turn this rule off for now.

Running Dovecot-1.1.5, I see this assertion failure: Panic: pop3-login: file sasl-server.c: line 75 (authenticate_callback): assertion failed: (client->auth_request == request) Error: pop3-login: Raw backtrace: 2 pop3-login 0x000000010000ac41 default_fatal_finish + 41 -> 3 pop3-login 0x000000010000acac i_syslog_fatal_handler + 0 -> 4 pop3-login 0x000000010000a446 i_info + 0 -> 5 pop3-login 0x00000001000053a2 authenticate_callback + 126 -> 6 pop3-login 0x000000010000841c auth_client_input_fail + 280 -> 7 pop3-login 0x0000000100007910 auth_client_input + 358 -> 8 pop3-login 0x000000010000e074 io_loop_handler_run + 272 -> 9 pop3-login 0x000000010000d449 io_loop_run + 38 -> 10 pop3-login 0x0000000100004864 main + 1572 -> 11 pop3-login 0x00000001000012fc start + 52 Error: child 1302 (login) killed with signal 6 This happens when I feed multiple user/pass lines to Dovecot all at once like this: $ telnet gromit 110 Connected.

IMAP login does not crash when presented with multiple login commands, but it does not read them all at once and needs prodding (in the form of extra command lines sent later on) to read them. Actually it appears to read the first two lines then stops reading until more data comes in: $ telnet gromit 143 Connected. Escape character is '^]'. * OK Dovecot ready. a login a b b login c d c login e f d login g h e login i j a NO Authentication failed. b NO Authentication failed. c NO Authentication failed. d NO Authentication failed. e NO Authentication failed. * BAD Error in IMAP command received by server. * BAD Error in IMAP command received by server. * BAD Error in IMAP command received by server. * BAD Error in IMAP command received by server. ^] telnet> q Connection closed. You probably don't care about the odd imap-login behavior, but I tried it and mentioned it just for completeness after seeing pop3-login crash.

[Dovecot] Best configuration of dovecot for limit Outlook problems with IMAP
by Alessio Cecchi 29 Oct '08

29 Oct '08

Hi, in some installation where users using IMAP and Outlook Express I have some problems. Outolook randomly presents problems in messages retrieving, for example: "Outlook Express is unable to retrieve the requested message because the server no longer has the message available.... server response: Fecth Completed" or "Message could not be displayed" error message when I try to view an Outlook Express e-mail message I'm using dovecot 1.1.4 with qmail and vpopmail. This is my dovecot configure options: ./configure --prefix=/usr --sysconfdir=/etc/dovecot --localstatedir=/var --with-ssldir=/etc/ssl and this my dovecot config: # dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot-err.log info_log_path: /var/log/dovecot/dovecot.log ssl_cert_file: /etc/apache2/ssl/comun.crt ssl_key_file: /etc/apache2/ssl/comun.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_greeting: Ready login_process_per_connection: no first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_uid: 89 mail_gid: 89 mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: verbose: yes debug: yes passdb: driver: checkpassword args: /home/vpopmail/bin/vchkpw userdb: driver: prefetch args: uid=89 gid=89 home=/home/vpopmail/domains/%d/%u plugin: quota: maildir What further changes to the configuration of dovecot could I do? Do you have other suggestions?

[Dovecot] Dovecot and quota enforcement - only reporting?
by dovecot＠corwyn.net 29 Oct '08

29 Oct '08

I'm currently setting up postfix and dovecot with virtual users (mysql), imap, and quotas. I'm setting the quotas using mysql. I have quotas working correctly, and I can telnet into the imap server, and submit . getquotaroot inbox and get back valid quota information. I get a maildirsize file in the Maildir directory. Very cool. When I delete mail and expunge it, the quota updates. However, inbound email doesn't appear to update the quota. Two questions, probably related: What causes the quota (which I presume is the maildirsize file) to update? Is there any actual quota enforcement, or just reporting? Because if I send mail to an account, even if it currently reporting (via maildirsize or . getquotaroot) that the user is over quota, they still can send and receive email. Thanks!
