Hello,
i have an ubuntu 8.04 LTS Virtual Server with Dovecot 1.0.10 and postfix. Now i tried to update Dovecot because i need Quota, which is not possible in 1.0 but in 1.2 So i added the packages to my /etc/apt/sources.list:
deb http://codex.xiaoka.com/apt hardy main restricted deb http://archive.ubuntu.com/ubuntu hardy-backports main universe multiverse restricted
and updated dovecot with aptitude. After this i killed the proc master and restarted postfix and dovecot but now dovecot is running but doesn't get any more mails from postfix. I had to downgrade back to 1.0.10 and after this all is working again.
I immediately looked into the mail.log, but i didn't see any clear errors. I uploaded the mail.log here, maybe someone could give me a hint, what it could be:
http://7fw.de/tmp/2011-01-24-23-38-mail.log
I started the update at 2011-01-23 at 23:00 and downgraded back at 2011-01-24 at 00:26. In the error.log i only have errors about inotify, which is not available on the ubuntu server (old kernel version, cannot be updated by provider).
I set in dovecot.conf:
mail_debug=yes auth_debug=yes auth_debug_passwords=yes
but this didn't help me.
Thank you, Kind regards, franc walter
