[Dovecot] Dovecot 1.0beta4 and Disconnected Problem
by Gerhard Wiesinger 04 Apr '06

04 Apr '06

Hello! Yesterday I upgraded from 1.0beta3 to 1.0beta4. I've major problems now with my inbox (quite large, 900MB) and another large folder. Thunderbird 1.5 connects and disconnects. I tried to delete the indexes of dovecot and thunderbird without any sucess. Finally I downgraded to 1.0beta3 and it works well again (Beta3 was running for a timeframe from when it came out and now without any problems). Config is the same as for 1.0beta3.

[Dovecot] Busyloop in dovecot-auth

SunOS pop01.unix 5.10 Generic_118844-26 i86pc i386 i86pc dovecot-1.0.beta3 Dovecot itself runs well, and was easy to confirgure with LDAP. However, I am seeing a cpu busy-loop in dovecot-auth.

[Dovecot] Re: Courier to Dovecot Maildir conversion
by Roger Weeks 03 Apr '06

03 Apr '06

We went through a courier to dovecot conversion. There are a couple of things that might be causing this problem. 1. Dovecot namespaces 2. Client configuration Your namespaces might not be taking into account the fact that courier prefixed all files and directories in the maildir with a dot (.). You can get around this a couple of ways. We had almost no IMAP clients under courier, so I renamed everything in our IMAP client directories away from .files and .directories, and used a default namespace without dots. Also some clients like Apple Mail needed an IMAP prefix like INBOX. to work with courier. I had to remove those with the dovecot namespace I set up. -- Roger J.

[Dovecot] hard quota example, 1.0b3
by Jeff A. Earickson 03 Apr '06

03 Apr '06

Timo, Here's an example of the filesystem quota issue: A user was near his hard filesystem quota, so he moved some junk to his Trash folder to clear disk space. He got the following error on his IMAP client: "Internal error occurred. Refer to server log for more information. {2006-04033 11:08:44]". My setup: Solaris 9, beta3 (soon going to beta4), mbox format, IMAP only. Home directories (where IMAP folders and index files go) have filesystem quotas. Jeff Earickson Colby College

This feature should not rely on plug-ins, mailbox format, etc. It should be built into the base code, IMHO. Jeff Earickson Colby College

[Dovecot] MySQL auth issues?
by Matthias Saou 03 Apr '06

03 Apr '06

Hi, Since my last email about RHEL4 problems on x86_64, I've kept trying to figure out what the problem might be, and just ran into a reply to an old email I sent to the list, which I had missed. It suggests that the issue might be in the MySQL authentication that I'm using. Here is a more detailed log entry, with auto debugging on : Apr 3 13:13:02 s1 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=::ffff:195.x.x.x rip=::ffff:195.x.x.x resp=AHBhcnRuZXJzQdNvbW1lcm3lZ2F0ZS5jb20Aa2F2YWthdmE= Apr 3 13:13:02 s1 dovecot: auth(default): client out: OK 1 user=x(a)domain.com Apr 3 13:13:02 s1 dovecot: auth(default): master in: REQUEST 70 22190 1 Apr 3 13:13:02 s1 dovecot: auth-worker(default): sql(x@domain.com,::ffff:195.x.x.x): SELECT maildir, 101 AS uid, 103 AS gid FROM mailbox WHERE username = 'x(a)domain.com' Apr 3 13:13:02 s1 dovecot: auth(default): master out: USER 70 x(a)domain.com maildir=domain.com/x/ uid=101 gid=103 Apr 3 13:13:02 s1 dovecot: pop3-login: Login: user=<x(a)domain.com>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x Apr 3 13:13:02 s1 dovecot: pop3(x(a)domain.com): ^GUnexpected eof found when reading file 'UNOPENED' (Errcode: 0) Apr 3 13:13:02 s1 last message repeated 2 times Apr 3 13:13:02 s1 dovecot: pop3(x(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/2, size=17174 Those "Unexpected eof found when reading file 'fileName'" messages are apparently from MySQL, as one can see here for instance : http://www.mysqlfreaks.com/errors/49.php Here is my relevant configuration (all the rest is the default) : login_greeting = Ready. verbose_proctitle = yes first_valid_uid = 101 default_mail_env = maildir:/home/vmail/%d/%n:INDEX=MEMORY auth_cache_size = 512 auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } The INDEX=MEMORY was added because of similar errors with the indexes : Apr 3 12:56:44 s1 dovecot: pop3-login: Login: user=<x(a)domain.com>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x, TLS Apr 3 12:56:44 s1 dovecot: pop3(x(a)domaine.com): Corrupted transaction log file /home/vmail/domain.com/x/dovecot.index.log: unexpected end of file while reading header Apr 3 12:56:44 s1 dovecot: pop3(x(a)domain.com): Corrupted transaction log file /home/vmail/domain.com/x/dovecot.index.log: unexpected end of file while reading header Apr 3 12:56:44 s1 dovecot: pop3(x(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 (this was when the auth_debug wasn't enabled) Here is my /etc/dovecot-mysql.conf file : driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=xxx default_pass_scheme = PLAIN password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 101 AS uid, 103 AS gid FROM mailbox WHERE username = '%u' I'm using MySQL 4.1.12-3.RHEL4.1 (the original RHEL4 packages), with the server on the same machine (hence the socket access). I was seeing this also with 0.9, not just 1.0 betas. With x86_64 packages, any slight change to the main dovecot.conf file can prevent dovecot from starting (segfault with "Unexpected eof found when reading file 'UNOPENED' (Errcode: 0)" message), whereas i386 packages work somewhat better. This is on the same machine with an i386 compatibility layer. Is anyone using MySQL auth successfully? Any help or pointers would be more than welcome.

[Dovecot] mbox-sync-update.c error
by Carlos Vicente 03 Apr '06

03 Apr '06

Hi, I think the problem is in Dovecot. I'm using both Evolution and Thunderbird on a Gentoo box. One of my folders keeps locking up and the clients can't retrieve the messages. The situation appears to be triggered by trying to move a message into that folder. Deleting the index files (under /var/log/dovecot/xxx/) solves the problem (temporarily). I get these error messages in the logs: Mar 31 15:10:34 dovecot: imap(cvicente): mbox sync: UID inserted in the middle of mailbox /home/xxx/Mail/xxx (93 > 3, seq=93, idx_msgs=3455) Mar 31 15:10:34 dovecot: imap(cvicente): file mbox-sync-update.c: line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > ctx->hdr_offset + pos + have) Mar 31 15:10:35 dovecot: child 32373 (imap) killed with signal 6 M I'm running dovecot-1.0_beta3 Hope this gets some attention from the developers. cv >In the maillog I get > > Mar 29 09:17:25 bree dovecot: imap-login: Login: user=<hartr>, > method=plain, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured > Mar 29 09:17:25 bree dovecot: imap(hartr): mbox sync: UID inserted > in the middle of mailbox /var/mail/hartr (8 > 1, seq=2, idx_msgs=4) > Mar 29 09:17:25 bree dovecot: imap(hartr): file mbox-sync-update.c: > line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset > + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > > ctx->hdr_offset + pos + have) > Mar 29 09:17:26 bree dove

[Dovecot] imap processes remaing after dovecot shutdown
by Marten Lehmann 02 Apr '06

02 Apr '06

Hello, I'm using dovecot-1.0.beta3. When I shutdown dovecot (kill -term on the master-pid) the main process disappears, but all the child processes still remain. Why doesn't dovecot kill them as I shutdown the master-process? When I shutdown mysql, all child processes will be shutdown, too. When I shutdown apache, all child processes willbe shutdown, too. Thats what I expect on every application. Usually there is no need to shutdown dovecot. But for some reasons, from time to time 50 and more processes of one user are running and I don't know how else to get rid of them. I don't like to kill the child processes always manually. Regards Marten
