Hi Timo, hi all! Today i noticed imap throws segmentation faults and dumps cores. I looked into logs I can see: 2013-03-07T12:12:52.257986+01:00 meteor dovecot: imap(marcinxxx(a)kolekcja.mejor.pl) <7sRXtFPXYAA+eX93>: Error: Corrupted dbox file /dane/domeny/mejor.pl/mail/marcin//.mdbox/mailinglists/storage/m.75 (around offset=2779212): EOF reading msg header (got 0/30 bytes) 2013-03-07T12:12:52.258052+01:00 meteor dovecot: imap(marcinxxx(a)kolekcja.mejor.pl) <7sRXtFPXYAA+eX93>: Disconnected: Internal error occurred.

[Dovecot] 2.2.rc2: problem with acl_shared_dict
by Lutz Preßler 22 Mar '13

22 Mar '13

Hello, 2.2.rc2, configuration as before: acl_shared_dict=file:... The contents of this file is used for e.g. LISTing shared mailboxes. But even with file and directory beeing world writable, it's not written into on SETACL commands. Instead, at least sometimes (it seems to make a difference if GETACL is used before in the session) the imap process crashes on SETACL or DELETEACL. Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master: service(imap): child 13373 killed with signal 11 (core dumps disabled) Anything to do for further debugging? Working correctly with 2.1.15. Greetings, Lutz

[Dovecot] director's imap/pop3 login timeout
by Angel L. Mateo 21 Mar '13

21 Mar '13

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41 dovecot: imap-login: proxy(<user>): Login failed to 155.54.211.162:143: [UNAVAILABLE] Temporary authentication failure. [myotis32:2013-03-20 19:52:47] So, it seems it was trying to authenticate for 1 hour, after that it timed out the login. But this timeout is too long. Is this a director timeout? Or a backend timeout? How can I reduce it? -- Angel L.

[Dovecot] Log DNS revese IP address
by Juan Bernhard 21 Mar '13

21 Mar '13

Hi list. Is it possible to log the DNS reverse address of every login? I didnt find a variable *%{hostname}* but the wiki say it only works on *deliver_log_format* and not on *login_log_format_elements* Something like this: Mar 21 13:49:33 mailserver dovecot: pop3-login: Login: user=<myuser>, method=PLAIN, rip=10.10.10.15, lip=10.10.10.1, mpid=18712, *host=client02.example.com* Thanks! Regards. Juan

Hi, I have set up ImapcProxy based on the wiki2 page. My server is set up for no plain text auth without starttls. When I am trying to login in the proxy server, I am getting an error Unknown username/password. The log says: *dovecot: imap-login: Aborted login (auth failed, 1 attempts in 2 secs): user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<1pBG/03XogB/AAAB>* The server log: *dovecot: imap-login: Disconnected (tried to use disabled plaintext auth): rip=10.x.x.x, lip=10.x.x.y* Through wireshark, I found the username and password is going in plain text only to the server. How will I enable starttls in ImapcProxy before any communication starts?

[Dovecot] Problem with Prefetch User Database
by megodin＠inboxalias.com 21 Mar '13

21 Mar '13

Hi there Community, I am currently setting up a Dovecot Mailserver, which works fine with some basic configuration (Dovecot + Sendmail). Sending and receiving Mails is just fine. For improving timings, I wanted to activate the prefetch user database - but apparently it doesn't seem to work correctly - I hope you can help me out! When I activate the prefetch user database, every time I get a "passdb didn't return userdb entries" from my mail.debug logs. Here's my config: passdb { driver = pam } # (I authenticate via PAM which is itself configured to ask ldap server, ldap returns it back to PAM - so Dovecot only sees the PAM-authentication part) userdb { driver = prefetch } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } # My userdb is going over ldap. Relevant parts of /etc/dovecot/dovecot-ldap.conf.ext: . .. user_attrs = uidNumber=50014,gidNumber=2084,modem-quota=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uidNumber==50014,gidNumber=2084 I'm not sure.... maybe it's because of the PAMLDAPPAM? Or am I missing out something other fundamental? Thanks for any insights, Megodin --- Alle PostfÃ¤cher an einem Ort.

by Andre Rodier 21 Mar '13

Hello everyone, Is it possible to configure the zlib plugin to compress the emails in one folder only? I would like to compress the emails when they are stored in my 'Archives' folders and sub folders. Thanks, André Rodier.

[Dovecot] ulimit -n in start-script
by Peer Heinlein 21 Mar '13

21 Mar '13

Hi! Even on midrange-systems it's necessary to set "ulimit -n" to a higher value then the system default of 1024. I'd prefer having this already prepared: In /etc/defaults/dovecot we should add: # Set amount of "open files" / ulimit -n ULIMIT_OPEN_FILES=16884 In /etc/init.d/dovecot we should add: # Set amount of open files / ulimit -n [ -n "$ULIMIT_OPEN_FILES" ] && ulimit -n $ULIMIT_OPEN_FILES Peer -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-42 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin
