I think someone else is responsible for the Debianization of Dovecot, not Timo.

[Dovecot] Dsync Permissions Issue
by Asai 16 Sep '11

16 Sep '11

Greetings, I recently upgraded Dovecot from 1.2 to 2.0.14, for purposes of using Dsync to migrate emails from one server to another. I'm using MySQL for authentication. However I get this error message when I try to run Dsync, and after looking around for an answer, I'm at a bit of a loss: [root@triata ~]# dsync -v -u asai(a)globalchangemusic.org backup ssh -p22222 vmail(a)xx.xxx.xx.xxx dsync -u asai(a)globalchangemusic.org vmail(a)xx.xxx.xx.xxx's password: dsync(vmail): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +r perm: /var/run/dovecot/auth-userdb, euid is not dir owner) dsync(vmail): Fatal: User lookup failed: Internal error occurred.

[Dovecot] Shared folder not listing
by Tom Clark 16 Sep '11

16 Sep '11

Hi Timo, I've got a weird problem on our dovecot. We're trying to setup private shared folder access. I have 2 users. tom(a)mailbox.com and system(a)mailbox.com. I have set the ACL's on all the folders (and subfolders) on system(a)mailbox.com. However, I'm not getting any of them listed when I check tom(a)mailbox.com <mailto:tom@mailbox.com's> 's IMAP folders. Our configuration is below (we're migrating from Courier hence the INBOX.): In 10-mail.conf: namespace { type = private prefix = INBOX. separator = . inbox = yes list = yes hidden = yes } namespace { type = shared separator = . prefix = INBOX.Shared.%%u location = maildir:%%h/Maildir:INDEX=~/Maildir/Shared/%%u subscriptions = no list = children } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins imap_acl } In 90-acl.conf: plugin { #acl = vfile:/etc/dovecot/acls:cache_secs=300 acl = vfile } # To let users LIST mailboxes shared by other users, Dovecot needs a # shared mailbox dictionary. For example: plugin { acl_shared_dict = file:/var/vpopmail/domains/%d/shared-mailboxes } Have I missed anthing!?!? Thanks in advance! Tom

[Dovecot] Maildir "locking"
by Attila Nagy 15 Sep '11

15 Sep '11

Hello, I'm looking for the alternative of qmail's chmod -t (sticky bit on the maildir root) for Dovecot. What I'm trying to achieve with this lock: - Dovecot lmtp should give back a temporary error (so the email will be deferred and re-delivered later) - all other Dovecot daemons (pop, imap) should work as usual, but should not alter maildir contents (they can modify their own files, like indexes, logs etc) What is the best way to do this? If there is no such thing currently, would it be hard to implement the sticky bit checking on the root? Thanks,
