[Dovecot] enourmous amount of disc writes
by Rainer Sigl 17 Jun '09

17 Jun '09

Hi List, on my mailserver (exim4, dovecot 1.0.0, postgresql, ubuntu dapper, about 500 users) I record an enourmous amount of disc writes (up to 18000 blocks written each second) in the time where most of users are active. This IO activity causes wait-states on the disc interface (RAID5) and finally slows down my mailmachine. Is there a explanation for these disc writes respectively is there a possibility to minimize this activity. Stopping Dovecot on this machine causes stopping most of the disc activity.

[Dovecot] expire-tool --test: timestamps

16 Jun '09

$ /usr/sbin/dovecot --exec-mail ext expire-tool --test Info: Trash: timestamp 1243963680 (Tue Jun 2 19:28:00 2009 ) -> 1244307774 (Tue Jun 2 19:28:00 2009 ) Both human readable timestamps are equal as ctime() returns a pointer to a static buffer. In addition there are some newline characters added by ctime().

[Dovecot] v1.2.rc5 imap ignores configuration reloads
by Pascal Volk 16 Jun '09

16 Jun '09

Hi Timo, after changing the mail_executable in the imap {…} section I have to restart Dovecot v1.2.rc5, otherwise the changes are not accepted. With Dovecot v1.1.x (tested with v1.1.11 and v1.1.16) it's enough to send a SIGHUP to the dovecot process. Regards, Pascal -- The trapper recommends today: c01dcofe.0916521(a)localdomain.org

[Dovecot] compressed mbox patch
by Axel Thimm 16 Jun '09

16 Jun '09

Some ages ago there existed a compressed mbox patch, but now all I can find are posting about it. Does such a beast exist and would it remotely apply to today's dovecot? If not, is there any hope that something like that emerges? Thanks! -- Axel.Thimm at ATrpms.net

[Dovecot] Marking message read after delivering to folder
by Nikolay Shopik 16 Jun '09

16 Jun '09

I've copying messages automatically to sent folder if it sent via our SMTP. Problem is Deliver can't mark message as read on deliver. Does that possible to accomplish using global sieve rule? I'm not familiar with sieve code syntax, know very basics. Also I know there different implementation in Sieve between 1.0, 1.1 and 1.2. Thanks

[Dovecot] Authentication cache, failure to login after changed password
by Tom Sommer 16 Jun '09

16 Jun '09

Hi, I have an issue with the authentication cache. When a user changes his password, the cache doesn't seem to get flushed. Meaning the user is unable to log in to his IMAP account after changing his password. Flow: - Log into IMAP account using pass1 - Approved - Stored in auth cache - Change password to pass2 in MySQL - Log into IMAP account using pass2 - Access is denied - Restart dovecot - Log into IMAP account using pass2 - Approved I'd really like to continue to use the auth cache, is there any solution to the above? perhaps a way to debug the cache and auth process? I wasn't able to activate auth_debug without restarting Dovecot and solving the problem. Using version 1.1.1, MySQL userdb, with "nopassword=Y". Maybe it's due to nopassword? Thanks -- Tom
