[Dovecot] Dovecot's deliver trouble (...probably bug?)
by Serge D 10 Jan '07

10 Jan '07

Hello everybody! I am a Linux admin trying to move my mail system based on qmail to the software which is more spam-protected: exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot from src.rpm (for fc4). During the testing stage I've discovered two troubles: 1) the problem with deliver (...I'm not sure it's a really bug). Here is relevant part of my /var/log/messages : ------- Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: serge(a)test.net Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: home=/var/spool/mail/test.net/serge/ Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: uid=500 Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: gid=12 Jan 3 10:40:37 serge deliver(serge(a)test.net): setuid(500) failed: Operation not permitted ------- -- my system is fc4 based Linux. uid/gid are according to /etc/dovecot-sql.conf : user_query = SELECT maildir AS home, 500 AS uid, 12 AS gid FROM mailbox WHERE username = '%n@%d' AND active='1' I was trying to chown 500.12 /var/spool/mail -R , chmod u+s ...etc, but it does not helps. Please, help. I don't want another MDA, people adviced me dovecot as good and well tested solution. I have already spent about two work days to configure and test it... 2) Because of mentioned above problem deliver generates a bounce message for exim, and here is a bug with e-mail in the header. It was taken "as is" from the queue of Exim -- have a look at "Return-path:", "envelope-from" and "Sender:" Because of these errors exim can not deliver the message back to sender. It freezes it, ...trying again, ...freezes ... etc... -------------------------------------------------- 1H252L-0004jZ-F3-D This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: serge(a)test.net local delivery failed ------ This is a copy of the message, including all the headers. ------ Return-path: <"testuser(a)test.net"@test.net> Received: from serge.lc.test.net ([10.0.0.5]) by serge.lc.test.net with esmtpa (Exim 4.62) (envelope-from <"testuser(a)test.net"@test.net>) id 1H252K-0004jT-U5 for serge(a)test.net; Wed, 03 Jan 2007 14:16:05 +0200 Message-ID: <459B9E84.9070607(a)test.net> Date: Wed, 03 Jan 2007 14:16:04 +0200 From: test uset <testuser(a)test.net> User-Agent: Thunderbird 1.5 (X11/20060119) MIME-Version: 1.0 To: serge(a)test.net Subject: =?KOI8-R?Q?=D4=C5=D3=D4_=D0=D2=CF=C8=CF=D6=C4=C5=CE=C9=D1?= Content-Type: text/plain; charset=KOI8-R; format=flowed Content-Transfer-Encoding: 8bit Sender: "testuser(a)test.net"@test.net Test message body. ------------------------------------ Here is an original message from e-mail client ( just to make sure that it was made proper way): ------------------------------------ > From - Wed Jan 03 18:18:54 2007 X-Mozilla-Status: 0001 X-Mozilla-Status2: 00800000 Message-ID: <459BD76D.4090903(a)test.net> Date: Wed, 03 Jan 2007 18:18:53 +0200 From: test uset <testuser(a)test.net> User-Agent: Thunderbird 1.5 (X11/20060119) MIME-Version: 1.0 To: serge(a)test.net Subject: =?KOI8-R?Q?=D4=C5=D3=D4_=D0=D2=CF=C8=CF=D6=C4=C5=CE=C9=D1?= Content-Type: text/plain; charset=KOI8-R; format=flowed Content-Transfer-Encoding: 8bit Test message body. ---------------------------------------------------------- As for POP3 with dovecot, it seems working OK. Dovecot generates mail directories according to the user data returned by SQL, and creates index files proper way - everything with given uid.gid = 500.12 ... If you will need some extra piece of information, or my configs or logs -- please feel free to ask for it. Any kind of help: advices, URLs, patches, etc.., are welcome. I badly need to bring up this new system as soon as possible. Thank you in advance. Best regards, Serge www.cis.by

[Dovecot] deliver rewrites envelop-sender
by Ralf Becker 10 Jan '07

10 Jan '07

Hello, we are currently using sendmail, procmail, uwimap and qpopper. We are planing to replace uwimap and qpopper with dovecot. Which seems to be a very good idea :-) But: Sendmail and Procmail will not be replaced. Now I've realized that deliver rewrites existing "From <....> ..." header lines to ">From <...> ..." and adds it's own "From "-line. Example: -------- My procmailrc end with :0 | deliver -d beckerr Mails are deliver to my INBOX, but * From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... is rewritten to * From MAILER-DAEMON Sun Jan 07 17:37:44 2007 * > From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... Is there a (simple) way to prevent deliver from doing so? OR In case "-f <envelop sender>" is not given, could deliver 1) read the envelop sender address from the "From <...>" line, 2) remove the line and 3) add it's own using the formally extracted sender address? This sounds best for me and would cover the problem most effective... BTW: I've found the "dovecot deliver patch for procmail" and it looks really good (http://dovecot.org/pipermail/dovecot/2006-July/014656.html) but it seems to me, that the "From " line problem is solved by optionally removing the whole line, so deliver would use it's own default "From MAILER-DAEMON "-line ... and this in fact the problem Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Disable TLS on port 143?
by Jackie Hunt 10 Jan '07

10 Jan '07

Hi all, Is there a way to disable the TLS support provided by Dovecot on port 143? I'd like to run SSL on 993, so as far as I can tell I can't use ssl_disable, since the will disable SSL. I'm looking for the equivalent of an ssl_disable_tls setting. Thanks much, Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] [minor] stale auth-worker sockets
by Luigi Rosa 09 Jan '07

09 Jan '07

I was fooling around the /var/run/dovecot directory and I noticed a lot of stale auth-worker.xxxxx sockets, probably left there by unexpected termination of old versions of Dovecot. Just to know who does what, have I to clean up the stale sockets, or a future version of Dovecot will get rid of this unused sockets? Ciao, luigi -- / +--[Luigi Rosa]-- \ Syntactic sugar causes cancer of the semi-colons;

[Dovecot] dovecot rc7 assert, core
by Jeff A. Earickson 09 Jan '07

09 Jan '07

Hi, Wow, I haven't had an assert/core in dovecot in a long time. Here goes: Setup: Solaris 10, dovecot built with gcc 4.1.1, imap and imaps only. User's home directory lives on a ZFS filesystem, but I don't think that makes a difference. So does every other user here (>3K). Assert: IMAP(mulepri): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) gdb backtrace and other poking at the core is attached.

Hi, I tried to use DSA certificate today and it did not work very well. Is Dovecot supposed to work only with RSA? -- Vaclav Haisman

[Dovecot] Automatic mail script?
by Andreas Andersson 08 Jan '07

08 Jan '07

Hello! I am setting up a Dovecot mailserver for around 2000 people with: sendmail + dovecot + squirrelmail + spamassassin and some plugins. I have the Imap quota working in mboxes with this quota commands: plugin { # 10MB quota limit quota = dirsize:storage=10240 } It worked good in Squirrelmail, but the person that only use some imap program (outlook, eudora) don't get the info when theirs account will be full of mail. So can someone give me a good script for a automatic mail. I want to send a mail to a user when they are nearly exceeded their limits, so they can start cleaning theirs account. Are this possible or how should I solve this problem? /Andreas

[Dovecot] unable to read mail - file istream-raw-mbox.c: line 499...
by Chris H. 08 Jan '07

08 Jan '07

Greetings all, I (nor anyone else) am suddely unable to read mail. Dovecot dumps the following in it's log: # BEGIN LOG ENTRIES # dovecot: Jan 07 18:15:52 Info: imap-login: Login: user=<username>, method=PLAIN, rip=::1, lip=::1, TLS dovecot: Jan 07 18:15:52 Error: IMAP(username): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) dovecot: Jan 07 18:15:52 Error: child 1584 (imap) killed with signal 6 # END LOG ENTRIES # NOTE: 'username' represents the users name at that time. The users subscribed to folders all show up. But no mail is visable. Dovecot is leaving username.lock files in /var/mail as well. It doesn't do this on my other servers running dovecot. They are using older versions of dovecot tho. Does anyone know what might be causing these problems? Relavent info follows: Dovecot version: 1.0.r15 OS: freebsd-5.5 Thank you for all your time and consideration. -- panic: kernel trap (ignored) ----------------------------------------------------------------- FreeBSD 5.4-RELEASE-p12 (SMP - 900x2) Tue Mar 7 19:37:23 PST 2006 /////////////////////////////////////////////////////////////////

[Dovecot] trouble debugging
by Aaron Solochek 07 Jan '07

07 Jan '07

I want to switch away from bincimap, and I am having some trouble getting dovecot up and running. Something isn't working (I suspect it's a permissions problem) but the logs aren't really telling me anything interesting. I can authenticate and get a list of folders, but when I try to select a folder, I get the "Internal error" message that tells me to check the server logs. The server log shows: Jan 5 19:43:42 sausage dovecot: imap-login: Login: user=<aarons>, method=plain, rip=XXX, lip=XXX, TLS Jan 5 19:43:43 sausage dovecot: IMAP(aarons): Effective uid=1000, gid=1000 Jan 5 19:43:43 sausage dovecot: IMAP(aarons): Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, subscriptions=no Jan 5 19:43:43 sausage dovecot: IMAP(aarons): maildir: data=/XXX/aarons/Maildir Jan 5 19:43:43 sausage dovecot: IMAP(aarons): maildir: root=/XXX/aarons/Maildir, index=/XXX/aarons/Maildir, control=, inbox= How can I get better debugging info? I've tried all the debugging options in dovecot.conf. Thank you. -Aaron
