[Dovecot] Dovecot Virtual Users & Sendmail
by Chris Hogan 26 Aug '05

26 Aug '05

Not directly Dovecot, but a configuration problem. We have a working set-up with Dovecot+Procmail+Sendmail, using POP-before-SMTP. We want to be able to offer email accounts to some local schools, using SquirrelMail (keeps their costs & maintenance down). The whole arrangement is working, but we don't want to have to have 300+ School children as users of our Red Hat Enterprise server, so I've set up a passwd style file for authentication. This all works fine, they can access mailboxes & send emails, but to receive Sendmail is checking that they are unix users & bounces messages back if they aren't in /etc/passwd too. Has anybody ever got Sendmail working with Dovecot virtual users? Or is it time I switched to Postfix? Chris Hogan

[Dovecot] 1.0alpha1: assert and core
by Jeff A. Earickson 26 Aug '05

26 Aug '05

Hi, I've been running 1.0alpha1 in production since August 18, and got my first assert and core yesterday. Otherwise it has been running flawlessly. My setup: Sun E220R, Solaris 9, compiled dovecot with gcc 4.0.1, configured dovecot like so: #!/usr/bin/sh VERSION=1.0-alpha1 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl > configure.out The syslog message: Aug 25 04:15:43 emerald dovecot: [ID 107833 mail.error] IMAP(user): file mbox-sync-update.c: line 442 (mbox_sync_update_header_from): assertion failed: (ctx->mail.uid == 0 || ctx->mail.uid_broken || ctx->mail.uid == mail->uid) Gdb analysis of the resulting core file is attached, I hope this helps. The user's mailbox is 41003432 bytes in size. Jeff Earickson Colby College

So if it happens, it's Mysql library bug. It isn't a bug of mysql or dovecot. It's the most simple problem: mysql permissions :P In mysql 127.0.0.1 and localhost are differents things, and if you copy the user (posta in my case), it doesn't copy the password (and so it works without a password). And more: if you put password, you have to flush privileges.

[Dovecot] Thread sorting problem
by Greg Trounson 24 Aug '05

24 Aug '05

I've just installed Dovecot on a Debian Sarge machine and am seeing some very strange thread sorting. In Mozilla Mail and Thunderbird on both Fedora and Debian clients my threads served up by Dovecot look like this (number denotes message time): |-11 | `-12 |-2 |-3 |-4 | `-5 | `-6 | `-7 | `-8 |-1 `-9 `-10 Where the exact same threads served by Sendmail/imap look like this: |-1 |-2 |-3 |-4 | `-5 | `-6 | `-7 | `-8 |-9 | `-10 |-11 | `-12 Squirrelmail shows the threads correctly in both cases too, so I suspect there might be something funny going on with how Thunderbird handles Maildir threads. I notice that Dovecot doesn't support the THREAD=ORDEREDSUBJECT capability, might that have something to do with it? thanks, Greg

[Dovecot] verbose imap logging
by Jens Laas 24 Aug '05

24 Aug '05

Implements more verbose imap logging (when client exits). Similar to existing logging in POP3. Due to the nature of imap and my incomplete understanding (of the dovecot code) the session statistics reported have varying accuracy. Much better than nothing IMO.

[Dovecot] public/private email accounts
by Ashvin Meetoo 24 Aug '05

24 Aug '05

Hi, I am running FC4 with postfix/dovecot/amavisd-new etc on my box with 50 staff email accounts (say 10 per 5 departments)... everything is working ok... I want to create 5 more accounts for each department (to be redirected to respective staffs, e.g. sales(a)xyz.com) as well one for everyone... that can be easily done by creating an account and modifying the .forward file in the /home/<user> folder. My great concern is that if by a virus attachment or spam is not detected and sent to everyone(a)xyz.com, it will be replicated to 50 email addresses... what I want is to have the 6 accounts mentionned above to be used only by the personnel and not the outside world... is there a way of doing this? Thank you. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[Dovecot] Well, "Hard filesystem quota can also be problematic"
by Jeroen Scheerder 24 Aug '05

24 Aug '05

"Hard filesystem quota can also be problematic", quoth <http://www.dovecot.org/>. Since we actually use quota for our userbasg, this merited further investigation. Using 1.0-stable, we enabled quota on /var and /users filesystems, and set very low quota for a test account. Then we had some mail delivered on it, and we moved some messages about. At some point, Thunderbird started to croak about "The current command did not succeed. The mail server responded: Internal error occured. Refer to server log for more information. [<timestamp>].", "The current command did not succeed. The mail server responded: .", "The current command did not succeed. The mail server responded: Out of disk space." This I can live with. Hoever, at some point in our experiments we also found that a mailbox (mbox format) that did contain a few dozen messages suddenly was truncated to 0 bytes. Not so hot. Can anyone tell me whether or not there is, or will be, some way of using dovecot on a system with quota without risk of data loss when quota limits are reached? How do people cope with this? Regards, Jeroen. p.s. That first error message gave rise to the enclosed patch. diff -r -c1 dovecot-1.0-stable-patched/doc/auth-protocol.txt dovecot-1.0-stable/doc/auth-protocol.txt *** dovecot-1.0-stable-patched/doc/auth-protocol.txt Wed Jul 27 08:08:35 2005 --- dovecot-1.0-stable/doc/auth-protocol.txt Mon Jan 31 17:37:54 2005 *************** *** 171,173 **** !
