[Dovecot] pre-1.0.rc6 / index file problems? try this
by Timo Sirainen 10 Jan '07

10 Jan '07

People who have had "duplicate header extension" and whatever other random index file corruption problems, please see if this fixes anything: http://dovecot.org/list/dovecot-cvs/2006-December/007315.html The change is also in the latest nightly snapshot (http://dovecot.org/ nightly/dovecot-latest.tar.gz). You could in general treat the latest snapshot as "pretty much the same as the 1.0.rc16 release", so some testing for it would be nice. I've updated autotools that were used to build the snapshot, does anyone have problems with compiling the snapshot? I'm going to build the 1.0rc16 release using the same autotools. rc16 has several changes intended to make Mac OS X's HFS+ happy. This is mostly because currently the only computer I have is a Powerbook. I'll get a new Linux machine in a couple of weeks hopefully. I've still about 50 unread/possibly unanswered mails. I'll try to get to them soon. Here's a list of all the important changes: * IMAP: When trying to fetch an already expunged message, Dovecot used to just disconnect client. Now it instead replies with dummy NIL data. * Priority numbers in plugin names have changed. If you're installing from source, you should delete the existing plugin files before installing the new ones, otherwise you'll get errors. * Maildir: We're using rename() to move files from tmp/ to new/ now. See http://wiki.dovecot.org/MailboxFormat/Maildir -> "Issues with the specification" for reasoning why this is safe. This makes saving mails faster, and also makes Dovecot usable with Mac OS X's HFS+ (after you also set dotlock_use_excl=yes, see below). + Added dotlock_use_excl setting. If enabled, dotlocks are created directly using O_EXCL flag, instead of by creating a temporary file which is hardlinked. O_EXCL is faster, but may not work with NFS. + If Dovecot crashes with Linux or Solaris, it'll log a "Raw backtrace". It's worse than gdb's backtrace, but better than nothing. + Added maildir_copy_preserve_filename=yes setting. + Added a lazy-expunge plugin to allow users to unexpunge their mails. + maildir quota: Added ignore setting to maildir quota, which allows ignoring quota in Trash mailbox. + dict quota: If dictionary doesn't yet contain the quota, calculate it by going through all the mails in all the mailboxes. + login_log_format_elements: Added %a=local port and %b=remote port - Doing a STATUS command for a selected mailbox (not a recommended IMAP client behavior) caused Dovecot to sync the mailbox silently. This could have lost eg. EXPUNGE events from clients, causing them to use wrong sequence numbers. - deliver was treating boolean settings set to "no" as if they were "yes" (they were supposed to be commented out for "no") - Running "dovecot" with -a or -n option while Dovecot was running deleted all authentication sockets, which caused all the future logins to fail. - maildir: RENAME and DELETE didn't touch control directory if it was different from maildir or index dir. - We treated internal userdb lookup errors as "user unknown" errors. In such situations this caused deliver to think the user didn't exist and the mail get bounced. - pam: Setting cache_key crashed - shared maildir: dovecot-keywords file's mode wasn't taken from dovecot-shared file. - dovecotpw wasn't working with PowerPC

[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.

[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.
