[Dovecot] corrupted mbox
by Jernej Porenta 27 Mar '10

27 Mar '10

Heya, we have two IMAP (UW-imap and dovecot) servers accessing the same mbox files for our users (don't ask why) and sometimes the UW-imap corrupts the mbox file. The mbox looks just like normal mbox except it does not have the proper 'From ' beginning of the file (usually there are some random tidbits in the begining of the file, which can be easily stripped to recover the working mbox). The problem is that if we use dovecot for POP3 server, the dovecot logs the mbox corruption just fine: POP3(username): Couldn't init INBOX: Mailbox isn't a valid mbox file But if we use IMAP for the same mailbox, dovecot opens the file and does not report any corruption, the user on the other hand sees just empty mailbox. So I was wondering if there are any possibilities to report mbox corruption with IMAP as well? thanks in advance, regards, Jernej

Hi Friends, i have a little problem with my Dovecot installation. The normal installation works very well and now i have to configurate dovecot that all member from a domain can access all mailboxes from this domain. I configurate the shared namespace and set the IMAP ACL Flag but i can't abonement the other mailboxes. I get a error in the logs: > 2010-03-18 10:03:04 IMAP(unglaub): Info: maildir: > data=/var/mails/e-c-o.at/kirchmeir:INDEX=/var/mails/e-c-o.at/shared/mitarbeiter/kirchmeir > > 2010-03-18 10:03:04 IMAP(unglaub): Info: maildir++: > root=/var/mails/e-c-o.at/kirchmeir, > index=/var/mails/e-c-o.at/shared/mitarbeiter/kirchmeir, control=, > inbox=/var/mails/e-c-o.at/kirchmeir > 2010-03-18 10:03:04 IMAP(unglaub): Info: acl: initializing backend > with data: vfile:/etc/dovecot-acl > 2010-03-18 10:03:04 IMAP(unglaub): Info: acl: acl username = unglaub > 2010-03-18 10:03:04 IMAP(unglaub): Info: acl: owner = 0 > 2010-03-18 10:03:04 IMAP(unglaub): Info: acl vfile: Global ACL > directory: /etc/dovecot-acl > 2010-03-18 10:03:04 IMAP(unglaub): Info: acl vfile: file > /etc/dovecot-acl//.DEFAULT not found > 2010-03-18 10:03:04 IMAP(unglaub): Info: Namespace > shared/mitarbeiter/kirchmeir/: Permission lookup failed from > /var/mails/e-c-o.at/kirchmeir > 2010-03-18 10:03:04 IMAP(unglaub): Info: Namespace > shared/mitarbeiter/kirchmeir/: Using permissions from > /var/mails/e-c-o.at/kirchmeir: mode=0700 gid=-1 > 2010-03-18 10:03:04 IMAP(unglaub): Error: > mkdir_parents(/var/mails/e-c-o.at/kirchmeir) failed: Permission denied In this case the User unglaub(a)e-c-o.at try to access the mailbox kirchmeir(a)e-c-o.at.

[Dovecot] mail_save_crlf Semantics
by Sabahattin Gucukoglu 27 Mar '10

27 Mar '10

Hi, It's not clear from the configuration when CR/LF conversion happens with mail_save_crlf set. Does this only happen with appends, or do all mails handled by Dovecot always get converted when opened? Cheers, Sabahattin

[Dovecot] cmusieve auto-reply and quota
by Mauro Faccenda 27 Mar '10

27 Mar '10

Hi there, I'm quite new to Dovecot, but already can tell that it is a really great work, congrats to the developers! But I'm having a little problem and couldn't figure it out how to solve. First, let me talk about my setup: I'm running Debian 5 (Lenny) with it's default Dovecot (common, pop3 and imap) packages (version 1:1.0.15-2.3+lenny1), I really would like to keep it this way unless I haven't another option. All authentication is made through a MS Active Directory and messages delivered to a virtual mailbox (/var/vmail/<domain>/<mailbox>), using Postfix as SMTP, that uses procmail (just for filtering the messages, not to deliver) that calls Dovecot's deliver like this: -- :0 w | $DELIVER -d $RECIPIENT -e -- $DELIVER points to /usr/lib/dovecot/deliver and $RECIPIENT is fed by Postfix in it's master.cf All this work great. Then I needed to enable quotas it's working as well. Here is the section that show how I've set it up: -- protocol lda { mail_plugin_dir = /usr/lib/dovecot/modules/lda mail_plugins = cmusieve quota postmaster_address = postmaster(a)do.ma.in hostname = mybox.do.ma.in auth_socket_path = /var/run/dovecot/auth-master quota_full_tempfail = no } -- I also want to run some sieve scripts just to be able to do some auto-replies (i.e. Out of office), and also it works well. Here is an example of a sieve I was using in some tests: -- require ["fileinto", "vacation"]; if header :contains "X-DSPAM-Result" "Spam" { stop; } vacation :days 1 :subject "Out of office reply" :addresses ["john.doe(a)do.ma.in", "jd(a)do.ma.in"] "I'm out of office, please contact Joan Doe instead. Best regards John Doe"; -- And as I said it works. But when I send a message to this mailbox that could exceed it's quota I get this on my logs: -- Mar 25 14:02:25 mybox postfix/pickup[21407]: 68D1DA82F: uid=103 from=<> Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)other.do.ma.in>: sent vacation response to <faccenda(a)other.do.ma.in> Mar 25 14:02:25 mybox postfix/cleanup[22119]: 68D1DA82F: message-id=<dovecot-1269536545-332912-0(a)do.ma.in> Mar 25 14:02:25 mybox postfix/qmgr[17299]: 68D1DA82F: from=<>, size=623, nrcpt=1 (queue active) Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)other.do.ma.in>: save failed to INBOX: Quota exceeded Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): sieve runtime error: Keep: Generic Error Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): sieve_execute_bytecode(/var/vmail/do.ma.in/john.doe/.dovecot.sievec) failed Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)do.ma.in>: Rejected: Quota exceeded Mar 25 14:02:25 mybox postfix/pipe[22086]: 7C666A825: to=<john.doe(a)do.ma.in>, relay=procmail, delay=1.1, delays=0.39/0/0/0.68, dsn=4.3.0, status=deferred (temporary failure) -- And every time the server tries again to deliver that message it re-sends the auto-reply. Is it an undesirable behavior, isn't it? Does anyone knows how to address it? Also, I thought that that configuration (using the -e parameter to deliver) and the "quota_full_tempfail = yes" would make give an permanent error, not trying to deliver that message again. What is wrong about it? Thanks in advance,

[Dovecot] A questions about consume_results (driver-pgsql.c)
by Rainer Weikusat 27 Mar '10

27 Mar '10

Code -------------- static void consume_results(struct pgsql_db *db) { do { if (!PQconsumeInput(db->pg)) break; if (PQisBusy(db->pg)) return; } while (PQgetResult(db->pg) != NULL); if (PQstatus(db->pg) == CONNECTION_BAD) io_remove_closed(&db->io); else io_remove(&db->io); db->querying = FALSE; if (db->queue != NULL && db->connected) queue_send_next(db); } --------------- This is the only part of the driver-pgsql.c code where a CONNECTION_BAD does not result in driver_pgsql_close being called. This will likely happen after the next query (from queue or a new one) failed because the connection was bad. Is there a reason for this?

[Dovecot] v2.0.beta4 released
by Timo Sirainen 27 Mar '10

27 Mar '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta4.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta4.tar.gz.sig I think this release is finally feature complete. There are still some bugs left to be fixed, but it's mainly in the dsync/mdbox area. v2.0.rc1 should hopefully be out in a couple of weeks. After that v2.0.0 will be released after no serious bugs have been found for a couple of weeks. Major changes since beta3: - auth process now runs as $dovecot_internal_user ("dovecot") by default. Auth worker processes still run as root by default, so this won't break PAM etc, but it could break passwd-file configurations. - It can now read v1.2's dovecot.conf file. If you find that it won't read your config, let me know and I'll see about adding code to fix it. It'll log warnings about each obsolete setting it sees. The easiest way to get rid of the warnings is to just translate your old config to v2.0: doveconf -n -c old.conf > new.conf - auth passdb/userdb configuration in example-config is now a bit different .. hopefully less confusing to new people than the old one. - added support for auth settings (including passdb/userdb) inside protocol sections, so it'll affect only those protocols - mail_plugins can now be set more easily. you can have a single global mail_plugins and then add more plugins to it like protocol imap { mail_plugins = $mail_plugins imap_quota } - doveconf finally shows all settings, including all protocol, local and remote sections - doveadm quota get|recalc command added. This is a plugin (yeah, doveadm now supports plugins!), so you must have a global mail_plugins=quota setting for the command to show up. - doveadm kick user/network to kick out logged in users (by sending TERM signal to processes). This was written by Pascal Volk. - and of course tons and tons of fixes all around

[Dovecot] CentOS yum update causing died unexpectedly
by dovecot＠corwyn.net 26 Mar '10

26 Mar '10

Running CentOS 5.x running a postfix/dovecot implementation. Dovecot 1.1.8. I just ran a full system update in my dev environment, and now I'm occasionally getting: Mar 26 07:15:43 example dovecot: auth(default): worker-server(test222(a)int.example.com,127.0.0.1): Aborted: Worker process died unexpectedly in /var/log/maillog. Any suggestions on where to look to figure out what's causing this? I don't see that error at all in the past 4 weeks of logs in production.
