auth: Error: PLAIN(user): Request 27511.1 timeouted after 150 secs, state=3
Since upgrading from Dovecot 2.0.beta4 + patches http://hg.dovecot.org/dovecot-2.0/rev/96496e1d3d12 and http://hg.dovecot.org/dovecot-2.0/rev/aefa279e2c70 to Dovecot 2.0.beta 5, I have started to see the subject error from Dovecot for SASL authentications. It doesn't happen every time, but it happens more often than not. It doesn't seem to affect Postfix's acceptance of the message.

Dovecot 2.0.beta3 Configuration issue (I think)
I have been running dovecot 1.2.10 without problems. I am trying to install 2.0.beta3. I have I think translated all my configuration customizations correctly, but I have problems. I can start dovecot, but I can't login, at least not with SSL. Here's my dovecot -n # 2.0.beta3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms

Problem configuring rawlog with 2.0beta6
The initial problem I was seeing after upgrade from 2.0beta5 to 2.0beta6 was error messages from my Android phone K9 client that dovecot was reporting -1 messages in various mailboxes. These mailboxes do have the special "Mail System Internal Data" message in them. In trying to get more information for debugging, I tried toenable rawlog using the same configuration I used successfully

Clarification wanted on mail_access_groups vs. mail_privileged_group
I have just upgraded to dovecot 1.0.13. All the documentation I can find in the example .conf file and the NEWS and ChangeLog files seems to say that the mail_privileged_group = mail setting is all I should need to make dovecot use group mail to create dotlock files. My understanding from what I read is that mail_privileged_group is used to set the group used while creating dotlock files in (in

Assertion error in Dovecot 2.2.6
Background. A while back I upgraded my phone to one currently using Android 4.1.2 and K9 mail 4.409. This phone/MUA combination seems at times to go crazy making IMAP connections. At first, I had mail_max_userip_connections = 30 (my largest imap account has 19 folders). The issue I had at that time was multiple errors like Oct 14 17:45:16 sbh16 dovecot: imap-login: Maximum number of connections

Clients show .subscriptions folder
Since upgrading from dovecot-2.1.rc1 to dovecot-2.1.rc3, some clients are showing a .subscriptions file in the user's mbox path as a folder. Some clients such as T'bird on Mac OS X create this file listing subscribed mbox files. Other clients such as T'bird on Windows XP show this file as a folder in the folder list even though it cannot be accessed as a folder (dovecot returns CANNOT

1.07 to 1.0.13 mail_extra_groups
I have just upgraded from 1.0.7 to 1.0.13. I read the comments in the example .conf file and it seemed what I needed to enable dotlock access to mailboxes in /var/spool/mail (writable by 'mail' group) was "mail_privileged_group = mail" so I removed the "mail_extra_groups = mail" that I had in 1.0.7 and added "mail_privileged_group = mail", but I got errors

Panic in dovecot 1.2.beta1
I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11. I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes" There are two kinds of pop3 users. In the attached log.txt file, user u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is coming through an ssh tunnel and retrieving their mail. u1 is able to interact normally with dovecot, but the fetchmail users

Some Dovecot LDA version sends MDN rather than DSN for overquota.
It appears that there is some version of the Dovecot LDA that is sending an RFC 3798 MDN rather than an RFC 3464 DSN to report non-delivery to a user who is over quota. See <https://bugs.launchpad.net/mailman/+bug/693134> for a discussion of this and <https://bugs.launchpad.net/mailman/+bug/693134/+attachment/1773018/+files/Automatically%20rejected%20mail.msg> for the actual MDN

Dovecot under brute force attack - nice attacker
Hi List, optimizing the configuration on one of our servers (which was hit by a brute force attack on dovecot) showed an odd behavior. Dovecot Version 1.0.7 (CentOS 5.2) The short story: On one of our servers an attacker did a brute force attack on dovecot (pop3). Since the attacker closed and reopened the connection after every user/password combination the logs showed many lines like
