[Dovecot] Signal 11 on deliver
by Matt 02 Feb '11

02 Feb '11

I just installed Postfix, MySQL, and Dovecot. Everything is working great (IMAP, POP, SMTP) except that I can't get incoming mail to deliver properly. Incoming mail logs the following: Feb 2 13:23:52 mail postfix/qmgr[2187]: CE0D41F0263: from=<mhoppes@[redacted]>, size=650, nrcpt=1 (queue active) Feb 2 13:23:52 mail postfix/pipe[3594]: CE0D41F0263: to=<mhoppes@[redacted]>, relay=dovecot, delay=0.32, delays=0.3/0/0/0.01, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/libexec/dovecot/deliver") Running /usr/libexec/dovecot/deliver -d mhoppes@[redacted] results in an e-mail being delivered to the recipient. Any thoughts on what my issue is?

[Dovecot] Can´t move folders in Outlook
by Mult´Moldes - Informatica 02 Feb '11

02 Feb '11

Hi, this is my first time in a mailing list, so I don´t know if I´m doing it right. My problem is that I cannot move a folder into another one, I can create them, move messages, etc, but I can´t move a folder, no matter what folder. It works fine With Thunderbird, but in Outlook Express or WLive Mail2009 it just doesn´t go! Must be something wrong with my .conf. I hope someone can help me please. dovecot --version 1.0.15 dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap listen: 192.168.10.2:210 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd

[Dovecot] override not working
by Paul A 02 Feb '11

02 Feb '11

Hi, I'm using dovecot 2.x and I'm using override so that only certain domains are allowed to use ACLs, however it does seem to be working even though I see the mail_plugins override in the logs. In the config file I have protocol imap { mail_plugins = quota imap_quota trash expire autocreate } Using the following password/user queries: password_query = SELECT username as user, password, if('%d'='virttest2.xxx.net', 'acl imap_acl',null) as mail_plugins, concat('/var/vmail/%d/', maildir) as userdb_home, concat('maildir:/var/vmail/%d/', maildir) as userdb_mail, 101 as userdb_uid, 502 as userdb_gid, CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM mailbox WHERE username = '%u' user_query = SELECT maildir, if('%d'='virttest2.xxx.net', 'acl imap_acl',null) as mail_plugins, 101 AS uid, 502 AS gid, CONCAT('*:bytes=', CAST(quota AS CHAR)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' Now in n the log I do see the mail_plugins override but for some reason I get an IMAP error when trying to share folders. out: OK 1 user=user20(a)virttest2.xxx.net mail_plugins=acl imap_acl quota_rule=*:bytes=512000000 ERROR: IMAP server does not support the ACL capability, sorry.

[Dovecot] Logging on syslog and selected dovecot files at the sametime
by Antonio Perez-Aranda 02 Feb '11

Is it possible to send logs to syslog and files set by log_path and log_info_path on config? Just two logs at the same time (not realtime). -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] automated mailbox trimming?
by Monique Y. Mudama 02 Feb '11

02 Feb '11

Hello all, If this is answered in the wiki, I apologize. Please point me to it and I'll be on my way ... This may be more of a MailDir-generic question, except that as I understand it there's some wiggle room in the naming of the message files. I've just switched from an mbox-based mail system to Dovecot with MailDir. With mbox, I used logrotate to keep some of my mailboxes (spam, sent, stuff like that) down to only the most recent messages. What's the best way to go about mailbox trimming with dovecot's implementation of maildir? I was thinking of writing a script to simply move or delete old files, but would I mess up dovecot's expectations for directory/file structure that way? My mail directories are in my user's home directory. I'm fine with writing a script or application (time permitting, of course), but before I do so, is there already a solution out there? In case it's relevant: $ dovecot --version 1.2.15 $ dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37 x86_64 Debian 6.0 log_timestamp: %Y-%m-%d %H:%M:%S ssl: required login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock auth default: passdb: driver: passwd-file args: /etc/dovecot/passwords userdb: driver: passwd userdb: driver: passwd-file args: /etc/dovecot/passwords

[Dovecot] Cannot authenticate with new Red Hat/Fedora SHA512
by John Cooper 01 Feb '11

01 Feb '11

RHEL6 and Fedora 14 use an improved password algorithm of SHA512 on a brand new install of the OS (:$6$ in shadow file). cat /etc/shadow user1:$6$<salt>$<password>:15006:0:99999:7::: I cannot get dovecot to authenticate. I've search for a way to change the default algorithm in dovecot and found you should use CRYPT but I don't know what to put in the /etc/dovecot/dovecot.conf or /etc/dovecot/conf.d/* Can this be done or do you need to use an alternate password file with MD5? Thanks, John.

[Dovecot] cgroup support
by Andreas Pelme 01 Feb '11

01 Feb '11

Hi, I am setting up a system that enforces cgroup restrictions when a user logs in via SSH, and for all the services that are run by a particular user. I am also running dovecot to give users IMAP/POP access to their mailboxes. However, to be part of a cgroup, PIDs must be explicitly added to the cgroup tasks file. So for now, all my processes are run with resource restrictions, except for Dovecot processes. It would be really cool if dovecots child/worker processes could be added the a cgroup in addition to the usual setuid/chroot protections that already exists. Adding a process to a cgroup is a matter of writing the PID to the correct cgroup tasks file. If this were implemented as an extra field in userdb, it could be very powerful, and allow for all kinds of resource management/accounting of dovecot processes. This would obviously not be cross-platform, since cgroups are a feature of the Linux kernel. Would that be a problem? Is support for cgroups something that could be considered for dovecot at all? Are there other ways to put dovecot processes in cgroups? I do not really have a patch or a plan for how everything would work out in detail. If this would be useful for dovecot, I would be happy to start hacking on a patch. Cheers Andreas
