[Dovecot] IMAP: Disconnected: BUG: Unknown internal error (Dovecot 1.0.3)

Hi, I am getting the following error in the server mail logfile: > Sep 2 18:39:44 h648123 dovecot: IMAP(<account>)(<PID>): Disconnected: BUG: Unknown internal error (mail_debug is on, but there is not really much context for this in the log file, ie. no log events for several minutes, and then it appears, all of a sudden). On the client side, it looks like this (with some context in case it matters; no exact times though, sorry): > [...] > S: * 17699 FETCH (UID 18226 FLAGS (\Seen)) > S: * 17700 FETCH (UID 18227 FLAGS (\Seen)) > S: * 17701 FETCH (UID 18228 FLAGS (\Seen)) > S: * 17702 FETCH (UID 18229 FLAGS (\Seen)) > S: * 17703 FETCH (UID 18230 FLAGS (\Seen)) > S: * 17704 FETCH (UID 18231 FLAGS (\Seen)) > S: * 17705 FETCH (UID 18232 FLAGS (\Seen)) > S: * 17706 FETCH (UID 18233 FLAGS (\Seen)) > S: * 17707 FETCH (UID 18234 FLAGS (\Seen)) > S: * 17708 FETCH (UID 18235 FLAGS (\Seen)) > S: * 17711 EXISTS > S: * 1 RECENT > S: U00328 OK Fetch completed. > C: U00329 UID FETCH 18238:* (UID RFC822.SIZE ENVELOPE BODYSTRUCTURE INTERNALDATE FLAGS) > S: * 17711 FETCH (UID 18238 RFC822.SIZE 0 INTERNALDATE "01-01-1970 00:00:00 +0000" FLAGS (\Seen \Recent) ENVELOPE (NIL NIL NIL NIL NIL NIL NIL NIL NIL NIL) BODYSTRUCTURE ("text" "plain" NIL NIL NIL "7bit" 0 0 NIL NIL NIL NIL NIL NIL NIL)) > S: U00329 OK Fetch completed. > C: U00330 UID FETCH 18238 (INTERNALDATE FLAGS) > C: U00331 UID FETCH 18238 (INTERNALDATE FLAGS RFC822.HEADER) > S: ) > S: !!

The client connection is simply closed. I am not getting a core dump for this; I am not sure whether I am supposed to. I configured Dovecot according to the instructions at http://www.dovecot.org/bugreport.html and core dumps generally work on my system, eg. I can force one using 'kill -s SIGSEGV <PID>' (where <PID> is a PID of one of the imap processes). What do I do with it? I am running Dovecot 1.0.3 (compiled from sources) on Suse 9.3. The client is The Bat! 3.99.x Professional. Client is allowed to open several concurrent connections to the IMAP server.

[Dovecot] What is your dovecot setup?
by Timothy Murphy 24 Sep '07

24 Sep '07

I'd be really grateful if someone running a dovecot IMAP (or IMAPS) server could tell me exactly how their email folders are arranged. What is the mail_location setting in /etc/dovecot.conf ? What are the directories (or some of them) containing mail messages? Does the client see an inbox folder? If so, what directory on the server contains these email messages?

[Dovecot] Is anyone using the dspam plugin for dovecot 1.1?
by Lars Stavholm 24 Sep '07

I'm about to try to adjust the dspam plugin code to dovecot-1.1, but before starting out on this, I thought I'd ask the list: anyone done it already? /L

[Dovecot] SEARCH NOT not working
by Julian Cowley 24 Sep '07

24 Sep '07

I think I've found the source of a bug which I first saw when running dovecot and pine (or alpine), which I finally tracked down by doing a protocol trace. In the IMAP session, the SEARCH command appears to have a problem with sets of messages and/or the NOT operator. Probably the best way to show this is by doing operations on a folder with ten messages in it. a select ten * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 10 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1190450101] UIDs valid * OK [UIDNEXT 11] Predicted next UID a OK [READ-WRITE] Select completed. Now, start doing some basic searches using message sets: b search (1:10) * SEARCH 1 2 3 4 5 6 7 8 9 10 b OK Search completed. OK, so far so good. Try the inverse: c search not (1:10) * SEARCH c OK Search completed. OK. d search not (1,10) * SEARCH d OK Search completed. Hmm, should have output 2..9. e search not (2,10) * SEARCH 1 e OK Search completed. Hmm.. that should have been 1, 3..9. f search not (2:10) * SEARCH 1 f OK Search completed. OK, expected. g search not (1,9) * SEARCH 10 g OK Search completed. Seems to affect other end of the range as well. h search not (2,9) * SEARCH 1 3 4 5 6 7 8 10 h OK Search completed. OK working again.

[Dovecot] dovecot with virtual and local users?
by Patrick Winnertz 23 Sep '07

23 Sep '07

Hello, I googled for a while in order to find a solution to make dovecot work with local and virtual users. My Mailserver setup looks like the following: virtual users are stored in a mysql database, and having their Mailbox here: /srv/mail/$domain/$uid/ Local users have a Maildir folder in their home directory. The only point i found in the web concerning this issue is this post here: http://www.dovecot.org/list/dovecot/2006-November/017478.html but I failed to understand the user_query. Can somebody who has such a setup running, or know how such a setup will work give me an advice, or a good point to read? Greetings Patrick ps: Please cc me, I'm not subscribed. -- .''`.

Re: [Dovecot] v1.1.beta1 released

On Sep 23, 2007, at 11:23 AM, dovecot-request(a)dovecot.org wrote: > Re: v1.1.beta1 released So far every thing is up and running well, (OS X 10.4 on a G5 machine). There are two things: From the logs: 1) dovecot: fd limit 256 is lower than what Dovecot can use under full load (more than 1152). Either grow the limit or change login_max_processes_count and max_mail_processes settings this is of course NOT a dovecot problem, it is just being nice and saying it can use more than the OS X defaults for open files. The next come from using the new Dovecot LDA: in trying to send mail, the following error occurs and I have not been able to find the setting to change this 2) postfix/qmgr[25767]: 2459A37F612: from=<from-email-address>, size=1226, nrcpt=1 (queue active) deliver(to-email-address): auth input: to-email-address deliver(to-email-address): auth input: uid=1000 deliver(to-email-address): auth input: gid=1000 deliver(to-email-address): auth input: home=path/to/ deliver(to-email-address): setgroups() failed: Operation not permitted postfix/pipe[6505]: 2459A37F612: to=<to-email-address>, relay=dovecot, delay=984, delays=984/0.03/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The solution so far is to go back to using the Postfix Deliver option. Where is the setgroups option being set in the LDA? Thank for you hard work!! Jerry Yeager

[Dovecot] kmail + IMAPS
by Timothy Murphy 23 Sep '07

23 Sep '07

I have dovecot IMAPS + kmail working perfectly on two laptops - I'm using one now - but I just tried starting it on a third laptop, and cannot get it running; kmail on the third laptop just waits indefinitely, saying "Retrieving Folder Contents Please wait ...". All 3 laptops are running Fedora 7, with more or less the same packages, all updated. (1) I suspect the problem lies with authentication. But how can I test this? Running "telnet <server> 993" gets the same response on all 3 laptops: [tim@elizabeth ~]$ telnet www.*.com 993 Trying 86.*.*.228... Connected to www.*.com. Escape character is '^]'. with no further response until I press ^]. I looked at <http://wiki.dovecot.org/TestInstallation> but this seems only to apply to IMAP on port 143. (2) kmail has an option to "Check What the Server Supports" under the Security tag, but pressing this just returns without any message, leaving whatever settings as they are. (On the laptops where kmail is working as an IMAPS client, the settings are changed to "Use TLS ..." and "Clear text".) I realise this is probably a kmail question, but shouldn't clicking on this option return some warning if it does not work? (3) I guess I don't understand exactly how TLS authentication works. Does installing openssl set up the correct certificates on server and client? Is there any documentation on this? Any suggestions or enlightenment gratefully received.
