But I still would like to know why the exec way doesn't work.

[Dovecot] Extremely custom mailbox locations
by Steve Kemp 13 Mar '09

13 Mar '09

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I can handle the custom login requirements I have, but I see no obvious way to create a mailstore from this information unless I build up a parallel symlink farm, such as: /imap/cvsrepository.org/{new cur tmp} I suspect if I fill cur/ with symlinks to each of the individual messages things will mostly work out OK, but I wonder if that is the best solution, or if there is a slim chance that I could serve this hierarchy without the intermediate step?

[Dovecot] which architecture to use?
by GVG GVG 13 Mar '09

13 Mar '09

Dear List, Based on the following installed environment: - OpenBSD (latest version!) - PostgreSQL - dovecot with SSL would like to have a mail server which accepts system as well as virtual users and being able to connect to their mailboxes either via an MUA (Thunderbird etc.) or a web interface (squirrel mail?). When using the web interface, non registered users should be able to creat e-mail accounts which will be dovecot virtual users! Which components should I use? Thanks

[Dovecot] Sieve - Backtrace after deliver(brabax): Panic: file sieve-cmu.c: line 264 (part_save): assertion failed: (buf->used - 1 == part->body_size.physical_size)
by brabax2 13 Mar '09

Hello, It's my first mailserver I set up. Thanks to everybody who contributes to dovecot. Dovecot works great for me! One thing I want to get rid off is this traceback error using dovecot with sieve. Somebody can help on this? System: Ubuntu server 8.10 dovecot --version 1.1.4 I filter for keywords in mail body with sieve. Mail is stored at lokal harddrive. I already deleted dovecot.index.cache - no success. Here is what logs say: sudo dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: postfix /var/syslog Mar 10 22:19:01 aquarius /USR/SBIN/CRON[23838]: (root) CMD (/etc/webmin/fetchmail/check.pl --owner --errors) Mar 10 22:19:04 aquarius deliver(brabax): Panic: file sieve-cmu.c: line 264 (part_save): assertion failed: (buf->used - 1 == part- >body_size.physical_size) Mar 10 22:19:04 aquarius deliver(brabax): Raw backtrace: /usr/lib/dovecot/deliver [0xb8068e01] -> /usr/lib/dovecot/deliver(i_syslog_fatal_handler+0x38) [0xb8068ee8] -> /usr/lib/dovecot/deliver [0xb8068695] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e394b6] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e3ac24] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e43b34] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e43e13] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_eval_bc+0x47e) [0xb7e4533e] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_execute_bytecode+0x125) [0xb7e4b4d5] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(cmu_sieve_run+0x325) [0xb7e3a785] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0xb7e38456] -> /usr/lib/dovecot/deliver(main+0x1229) [0xb7ff2c39] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7e6b685] -> /usr/lib/dovecot/deliver [0xb7ff0531]

[Dovecot] 1.1.12 release candidate
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/tmp/dovecot-1.1.12.rc.tar.gz I would have already released 1.1.12, but it needed the MAILBOXDIR change described below, and I'm slightly worried that it might have broken some special setup. So please test first and I'll release in v1.1.12 then in a few days. * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] Imap logout message on Dovecot restart
by RutgerM 12 Mar '09

12 Mar '09

I'm trying to receive a "Disconnected" message in my logfile for the connected imap-clients when I restart dovecot. When you disconnect a client, you receive the following message in your log: Mar 12 21:45:55 mail dovecot: IMAP(mailbox(a)domain.com): Disconnected: Logged out bytes=7496/22441 When a IMAP client is connected and Dovecot is restarted, this message is not shown. This should be solvable by a script like this: #!/bin/sh unset LOG_TO_MASTER export USE_SYSLOG=1 exec /usr/lib/dovecot/imap But this logs the user that runs the script into the imap server and when I terminate this terminal I get a "Disconnected" message for the local linux user, which I don't need of course. Is there a way to get to what I want ? I want to log my IMAP statics for every day and I need to "disconnect" my imap clients for it in some way to receive the Disconnected message and count from there. Thanks.

[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva
