[Dovecot] adding dovecot to webmin list of services
by Spyros Tsiolis 28 Oct '11

28 Oct '11

Hello , I am playing with webmin these days and find it really fun to install and use everyday. However, on the services option, amongst other services, the dovecot service is not shown. Does anyone out there have similar experience with webmin and dovecot and know how to make it appear there ? I am using CentOS (5.5/5.6/5.7) 32-bit Dovecot was installed manually and not from yum (.rpm) Dovecot v1.2.15 TIA, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] IMAP shows forwarding and vacation files
by Nico Suhl 28 Oct '11

28 Oct '11

Hello, I'm migrating our mailserver from a linux machine to solaris and got some small problems with our forwarding and vacation files, which are stored in the maildir of each user. I'm now using 2.0.15, on the old machine there was a dovecot 1. Now the problem is, that the .forward and .vacation files, which are used by exim, are shown as folders (they have a point...) in imap lists. This problem only occurs on the new solaris machine and not on the old linux system (with dovecot v1) or another testing machine with dovecot 2, which runs also under linux. userdb lookups are static with system account/group of exim. Is there any way to "hide" the .forward and .vacation files or do i have to rename or move them? Why are they shown here and not on our testsystems? regards, Nico Suhl

Dovecot reports to have looked in the system password file, failed, then looked in /etc/dovecot/users and found the user and logged them in. I think the problem happens later and you will have to show the subsequent log entries. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Configuring mbox and maildir formats - dovecot-1.2.15
by Albert E. Whale 28 Oct '11

28 Oct '11

I am transitioning an existing server from using exclusively mbox, to being able to support both mbox and then fully maildir formats. I need to support the mbox format until I can get everyone switched over to maildir. What do I need to to use in the config of /etc/dovecot.conf to support the default of mbox, and then the new Maildir format (users will get upgraded individually from mbox to Maildir, and need to be upgraded). Thank you. -- Albert E.

[Dovecot] Marathon Day 6 of First Install: MySQL Connection Problem
by Jack Fredrikson 25 Oct '11

25 Oct '11

Hi; This is my 6th day installing my first Postfix/Dovecot installation. The Postfix mailing list indicates I've got the MTA under control so now I'm seeking your help with the MDA. I get these errors with legitimate email addresses: Oct 24 11:47:38 myserver dovecot: auth-worker: Error: mysql(localhost): Connect failed to database (postfix): Access denied for user 'dovecot'@'localhost' (using password: YES) - waiting for 25 seconds before retry Now I've logged in myself: mysql -u dovecot -p Enter password: xxx and succeeded. What am I doing wrong? I've noticed that every time I restart dovecot I get this error in the dovecot-deliver.log: Oct 24 11:31:11 lda: Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-userdb) failed: Permission denied (euid=512(vmail) egid=512(vmail) missing +r perm: /usr/local/var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755) Oct 24 11:31:11 lda: Fatal: Internal error occurred. Refer to server log for more information. Every time I go to chmod 666 on that file, restarting dovecot wipes those permissions. How fix? Even when I fix that, I still get the "temporary failure". Please advise. TIA, Jack
