[Dovecot] problem in rc15 (proxy mode)
by Laurent Papier 03 Dec '06

03 Dec '06

Hi, I have test dovecot on one of my pop3/imap proxies (from rc10 to rc15). I immediately get a lot of error messages like this one : Nov 27 15:10:45 mproxy1 dovecot: pop3-login: file client.c: line 423 (client_unref): assertion failed: (client->destroyed) Nov 27 15:10:45 mproxy1 dovecot: child 21677 (login) killed with signal 6 A lot means one every 2 or 3 seconds.

[Dovecot] Deliver Root Setuid
by Láďa 03 Dec '06

03 Dec '06

Hi, I just configured my Postfix installation to deliver via Dovecot LDA. But because I use separate uids for virtual domains I had to set deliver to be setuid root. Altough I find this as frequent answer to this problem with deliver LDA I am not a 100% sure - basically because I try to avoid root setuids as much as I can. What should be better solution - to have all mailboxes with one owner or this setuid binary? My main reason for separate uids was filesystem quotas for whole domain. But my mail partition resides on XFS so I can do the same with directory quotas and I also noticed changes in quotas which should be also per domain in some next release or with patch. Thanks for any advice and also thanks for all great work on Dovecot. Láďa

[Dovecot] Too many open files

Do we really need to increase individual user maxfiles to >1024 ? Dovecot is set to 31768 so it is definately the user process here. Anything I can tweak in dovecot.conf to prevent this? Thanks!

[Dovecot] Dovecot hung or what?
by Odhiambo WASHINGTON 03 Dec '06

03 Dec '06

Here is my first major problem with dovecot. I am running rc15 on FreeBSD 6.1. I run dovecot supervised by DJB's daemontools. I run only the pop3 service. A colleague informed me that pop3 service was simply not responding. They could not rcv mail. When I checked the server, tail-ing dovecot.log, here is what was scrolling: [wash@nbi ~]$ tail -f /var/log/dovecot.log dovecot: Nov 23 18:04:11 Info: pop3-login: Disconnected: Inactivity: rip=196.200.37.94, lip=62.8.64.64 dovecot: Nov 23 18:04:11 Info: pop3-login: Disconnected: Inactivity: rip=196.200.42.212, lip=196.200.36.2 dovecot: Nov 23 18:04:12 Info: pop3-login: Disconnected: Inactivity: rip=196.200.35.130, lip=62.8.64.64 dovecot: Nov 23 18:04:13 Info: pop3-login: Disconnected: Inactivity: rip=168.144.108.27, lip=62.8.64.64 dovecot: Nov 23 18:04:14 Info: pop3-login: Disconnected: Inactivity: rip=168.144.108.8, lip=62.8.64.64 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=196.200.39.169, lip=62.8.64.64 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=41.220.126.2, lip=196.200.38.2 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=196.200.39.169, lip=62.8.64.64 dovecot: Nov 23 18:04:18 Info: pop3-login: Disconnected: Inactivity: rip=196.200.37.174, lip=62.8.64.64 dovecot: Nov 23 18:04:19 Info: pop3-login: Disconnected: Inactivity: rip=196.216.68.230, lip=62.8.64.64 dovecot: Nov 23 18:04:22 Info: pop3-login: Disconnected: Inactivity: rip=196.200.45.54, lip=62.8.64.64 dovecot: Nov 23 18:04:26 Info: pop3-login: Disconnected: Inactivity: rip=196.200.35.130, lip=62.8.64.64 dovecot: Nov 23 18:04:27 Info: pop3-login: Disconnected: Inactivity: rip=196.200.45.54, lip=62.8.64.64 dovecot: Nov 23 18:04:28 Info: pop3-login: Disconnected: Inactivity: rip=41.220.126.2, lip=62.8.64.64 dovecot: Nov 23 18:04:28 Info: pop3-login: Disconnected: Inactivity: rip=196.207.23.28, lip=62.8.64.64 dovecot: Nov 23 18:04:31 Info: pop3-login: Disconnected: Inactivity: rip=82.109.38.129, lip=62.8.64.64 dovecot: Nov 23 18:04:32 Info: pop3-login: Disconnected: Inactivity: rip=41.222.12.121, lip=196.200.36.2 ^C [wash@nbi ~]$ su Password: nbi# sh /usr/local/etc/rc.d/svscan.sh stop Stopping svscan. nbi# sh /usr/local/etc/rc.d/svscan.sh start Starting svscan.

[Dovecot] Pop3 migration (was Status of commercial support?)
by Francisco Reyes 03 Dec '06

03 Dec '06

Odhiambo WASHINGTON writes: > | Courier 4 POP migration to dovecot. > > This should be very easy, I think. > Once you know the uidl format used by Courier 4 POP. The migration is Courier 4 to Dovecot using Maildir format. I used some scripts I found on the net and adapted them. I got everything to come over (ie imap subscriptions), except POP3 UIDs. My Courier POP3-uid files look like: /2 19 1164413643 <message file name>,S=28985:2,S 29648 10:1164413643 <message file name>,S=5913:2,S 6042 11:1164413643 <message file name>,S=5121:2, 5236 12:1164413643 <message file name>,S=5257:2, 5373 13:1164413643 <message file name>,S=5106:2, 5215 14:1164413643 <message file name>,S=5618:2, 5745 15:1164413643 <message file name>,S=30619:2, 31353 16:1164413643 <message file name>,S=34785:2, 35609 17:1164413643 <message file name>,S=6695:2, 6852 18:1164413643 My pop3_uidl_format is pop3_uidl_format = %08Xu%08Xv Looking at what Dovecot generates on a brand new pop account the files look like: 1 1164413643 29 10 <message file name> 11 <message file name> 12 <message file name> 13 <message file name> ... and more with the same format... So I write an AWK script which creates the proper first line and gets for each line the message ID and message file name. Yet after I do the conversion and run a pop3 client against the migrated pop account, old mails are re-downloaded.

[Dovecot] cache_key assertion error 1.0.beta8
by Frank Cusack 03 Dec '06

03 Dec '06

I just added auth caching with pam, and I'm getting this error: dovecot: [ID 107833 mail.error] auth(default): file passdb.c: line 178 (passdb_init): assertion failed: (passdb->passdb->default_pass_scheme != NULL || passdb->passdb->cache_key == NULL) A google search turns up <http://www.dovecot.org/list/dovecot-cvs/2005-March/004117.html> which looks approx like this except the assertion above is in passdb.c. Anyway, is this a known problem in 1.0.beta8? I've been reluctant to upgrade to the rc's due to all the problems. -frank

Going to be transfering a number of domains from a Courier setup to Dovecot. Is there a way to get Dovecot to index the files before the users access their accounts?

[Dovecot] Status of commercial support?
by Francisco Reyes 03 Dec '06

Was going over the archives looking for any info on commercial support. Only found some emails back from 2005. Is there commercial support available? If not, any consultants that could help with an installation. In particular Courier 4 POP migration to dovecot.
