[Dovecot] Doveoct crashes: UID
by Peer Heinlein 23 Nov '10

23 Nov '10

We're running Dovecot 2.0.2 and sometimes a user creates several imap- prozesses, all of them hanging with the UID-command, using 100% of the CPU resources: root@mail:~# ps ax | grep UID 8005 ? R 266:52 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10342 ? R 250:33 dovecot/imap [user(a)example.com 192.168.5.5 UID] 10539 ? R 248:28 dovecot/imap [user(a)example.com 192.168.5.5 UID] 11150 ? R 245:03 dovecot/imap [user(a)example.com 192.168.5.5 UID] 11525 ? R 243:55 dovecot/imap [user(a)example.com 192.168.5.5 UID] This situation is triggered by two users only. Looks like their mailclient is sending a special command, that triggers the crash. Is it a bug or another problem? Is this a bug already fixed in Dovecot 2.0.3? - Fixed an infinite loop introduced by v2.0.2's message parser changes. Unfortunetaly I can't try an update at the moment. :-( Peer -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] pam authentication error
by Oliver Berse 23 Nov '10

23 Nov '10

Hi all, I compiled Dovecot 1.2.16 (on Debian 5/lenny) and followed the quick configuration guide (wiki.dovecot.org/QuickConfiguration) I just need plaintext authentication. After starting Dovecot I get "Last died with error" and in var/log/mail.err: Nov 23 15:06:55 debian dovecot: auth(default): Fatal: Support not compiled in for passdb driver 'pam' Nov 23 15:06:55 debian dovecot: dovecot: Fatal: Auth process died too early - shutting down In /etc/pam.d/dovecot: auth required pam_unix.so account required pam_unix.so In /usr/local/etc/dovecot.conf: passdb pam { args = * } So, what may be wrong with my configuration? Oliver

[Dovecot] Namespace help
by Joy 23 Nov '10

23 Nov '10

Dear All, I am currently using courier-imap which uses INBOX. namespace configuration now i am willing to use dovecot instead of courier-imap but without INBOX. namespace configuration means default namespace of dovecot which helps me to sort out no of mail client issues as well. I know that i can change the default namespace configuation of dovecot to work with courier-imap namespace but not willing to do that so suggest me something which can help me doing the same. Is it possible using postlogin script or something else ? Thanks Regards Piyush Joshi

[Dovecot] multiple IMAP ports, each announcing different capabilities
by Clemens Schrimpe 23 Nov '10

23 Nov '10

Hello - is it syntacticly possible to define different "imap_capability" settings per each inet-listener? I might have to provide a service through a caching proxy sitting in front of dovecot, which might involve restrictions re: the announced imap capabilities. Any hint is highly appreciated! Greetings, Clemens

[Dovecot] "list" ACL privilege ignored for LSUB command?
by Willie Gillespie 22 Nov '10

22 Nov '10

Hello, I am new to this list, so feel free to correct me if I do something wrong. I don't have a problem, just a question. The RFC which covers IMAP ACLs [1] states that one of the standard rights is: l - lookup (mailbox is visible to LIST/LSUB commands, SUBSCRIBE mailbox) If I have a shared or public namespace and have a mailbox for which I do not have lookup rights, Dovecot seems to do great with the LIST commands at not showing it to me. Two things I noticed though: SUBSCRIBE-ing to the mailbox is still successful LSUB will list mailboxes which I do not have lookup rights to I imagine the first issue is easy enough to correct since it's just another check before actually subscribing. The second issue seems a little more difficult in my mind since Dovecot seems to just dump the subscription files to the client without checking whether the mailbox is allowed or not. I imagine a similar issue popped up with the LIST command and that's why the dovecot-acl-list files exist. Anyway, am I right in my observations, or am I completely overlooking something obvious? Thanks! Willie [1] http://tools.ietf.org/html/rfc4314#section-2.1 Dovecot's wiki also indicates support for this in http://wiki1.dovecot.org/ACL#ACL_files I'm using version 1.2.9 with the acl and imap_acl mail_plugins in case that matters.

[Dovecot] Soft Quota for moving messages
by Tim Traver 22 Nov '10

22 Nov '10

Hi all, ok, I have an account that is over quota, but they are unable to move things to the trash, because the system is giving an error because of course it is over quota. Is there a quota setting that will let them move things to the trash without error? this of course would be so they could decrease their disk usage and become under quota again... Thanks, Tim.

[Dovecot] Workaround for evolution?
by Axel Thimm 22 Nov '10

22 Nov '10

Hi, evolution has a bug when it comes to closing and IDLE' connection: https://bugzilla.gnome.org/show_bug.cgi?id=628515 evolution does not send a DONE command, and dovecot properly answers with an error. evolution ignores this and seems to wait on another response. Timo, do you think there could be a setting for tolerating missing DONEs? Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] What is that error all about: "Timeout leak: 0x4bd230"
by Christian Rohmann 22 Nov '10

22 Nov '10

Hey dovecot-users, we are running dovecot 1.2.15 and are seeing some odd errors in our logfiles: --- dovecot.log --- 2010-11-22 12:34:56 imapserver local2.warning dovecot dovecot: IMAP(username(a)domain.tld): Timeout leak: 0x4bd230 --- /dovecot.log --- Those errors only appear if connections are done using IMAP (via Horde's IMP Webmail). With POP3 we don't see any of those errors. We actually don't see anything in general being broken or wrong (no errors on the webmail machines, no user complaints), but these errors are constantly being logged. Where would one start to look for the cause? Thanks for your help, Regards Christian

[Dovecot] Confused about Maildir
by Glen Lee Edwards 22 Nov '10

22 Nov '10

I'm trying to configure Dovecot 2.0.7. In the Dovecot Wiki for Maildirs it says that Maildirs are almost always located in ~/Maildir. I'm a Linux end user, not a programmer, so I may be wrong in this; but isn't the notation "~/" used for system users only to reference their home page; /home/<user>? If that's the case, then does that mean that Maildirs can only be used with system users and not with vmail accounts? Glen
