[Dovecot] Looking for HowTo Postifx, Dovecot and PostgreSQL
by Frank Lanitz 10 Feb '14

10 Feb '14

Hi folks, I know it's a bit a n00bish question, but I'm a little confused about this many different ways on setting up dovecot with postfix and using a PostgreSQL backend for virtual hosts. I've found this one quiet helpful: http://wiki2.dovecot.org/HowTo/DovecotPostgresql even it seems to be little outdated for recent versions of dovecot (the auth part of dovecot.conf). Also its lagging some inforamtions I wasn't able to find on my own (e.g. how to set password for a imap account). Can somebody give me a hint for a up-2-date howto for some noob as I am? Cheers, Frank

[Dovecot] Dsync Errors
by Asai 08 Feb '14

08 Feb '14

Greetings, I've seen something like this in another thread, about a month ago, but we're running into this error pretty frequently when we run dsync backup. Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x39ccc5f1c0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x39ccc5f2a5] -> /usr/lib64/dovecot/libdovecot.so.0 [0x39ccc5ebb3] -> dsync(dsync_brain_mailbox_tree_sync_change+0x41c) [0x42cc0c] -> dsync(dsync_brain_recv_mailbox_tree_deletes+0x10a) [0x42be7a] -> dsync(dsync_brain_run+0x4fc) [0x429cdc] -> dsync [0x42885b] -> dsync [0x4119ff] -> dsync(doveadm_mail_try_run+0x269) [0x411e09] -> dsync(main+0x358) [0x41a2c8] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3f4281d994] -> dsync [0x4111c9] We're running Dovecot 2.2.4 and the dsync command is this: dsync -u <username> backup maildir:/mnt/backups/<period>/<domain>/<username> When this happens to a particular users account I delete the backup and let it rebuild, which works for awhile, but then it happens again, and it seems to happen to particular users. Can you point me in the right direction to start troubleshooting this? Thanks. -- --Asai

[Dovecot] Auth socket can't listen using ssl
by Anthony Bourguignon 07 Feb '14

07 Feb '14

Hi, I'm using Dovecot 2.2.9 (debian package on testing). It seems that it's not possible to open an auth socket using ssl. I'm using this configuration : service auth { [...] inet_listener authxmpp-client { address = [ips] port = 5220 } inet_listener genericauth-client { ssl = yes address = [ips] port = 5221 } [...] } Both ports are running fine. But the 5221, which should listen in ssl (because of the "ssl = yes" as written in the documentation here : http://wiki2.dovecot.org/Services ) is using plaintext. If I telnet directly to it, the content is delivered on an unsecured socket. Is there a way to make ssl works on this kind of socket ? Thanks a lot

[Dovecot] Multiple ssl-certs on different ports with the same protocol
by myleetlist＠gmx.de 07 Feb '14

07 Feb '14

Hi, is it possible to use multiple ssl-certs on different _ports_ with the same protocol? I know I can configure multiple certs with the "local <ip>" setting*. But how is this (or similar) possible in v2.2.10: local :100 { protocol imap { ... } } local :101 { protocol imap { ... } } This would be useful in a loadbalancing setup, you don't waste IPs and the config files on different servers stay the same. * [http://wiki2.dovecot.org/SSL/DovecotConfiguration]

Hello everybody, Is it possible to authenticate both passdb and userdb in the director cluster and send passdb information (like home, mail_location,...) to the backend servers? I am using the lastest dovecot version. Thanks in advance!
