[Dovecot] How to purge mailboxes manually [dovecot_1.2.15]
by Emilio Nacelle 15 Apr '11

15 Apr '11

Hi, we have a linux network at the office. Mainly ubuntu and debian systems. Each user has it's own mail client, thunderbird, evolution, etc. In the mail server we use as the local delivery agent, dovecot 1.2.15 and the protocol imap. The users mailbox are in the server at /var/mail. Due to some kind of problem the mails that are set for delete in the mail client are not being deleted in the mailbox (if we check the mbox the mails are marked to be purged). Unless the owner uses something lowlevel shell mail client like pine to do the purge, the mails start to pile filling the account. Is this some known bug with a fix, or is there some routine we can run as admins to actually purged the mails set for deletion? (Like the "doveadm purge" in dovecot 2.0) Thanks a lot, looking forward to your answers, Emilio P.S: we would really like not having to install dovecot 2.0 :)

[Dovecot] Released Pigeonhole v0.2.3 for Dovecot v2.0.12
by Stephan Bosch 14 Apr '11

14 Apr '11

Hello Dovecot users, It's been a while since the last Pigeonhole release. This new release adds support for the new vacation-seconds extension, which allows the vacation extension to reply more frequently than every day and allows specifying this interval in seconds instead of days. I've also fixed quite a few bugs that were reported in the last couple of months. Changelog v0.2.3: * Sieve-filter tool: finished implementing basic functionality. It is not quite ready yet, but it is available for those willing to experiment with it (needs --with-unfinished-features config to compile). Also includes man page. + Vacation extension now inhibits replies to messages from sender listed in :addresses, thus preventing replies to one of the user's other known addresses. + Vacation extension: implemented the (draft) vacation-seconds extension. This also adds min/max period configuration settings. Refer to doc/vacation.txt for configuration information. - ManageSieve: fixed bug in UTF-8 checking of string values. This is done by discarding the original implementation and migrating to the Dovecot API's UTF-8 functionality. - Sieve command line tools now avoid initializing the mail store unless necessary. This prevents sievec and sieve-dump from failing when executed by root for example. - Enotify extension: fixed inappropriate return type in mailto URI parse function, also fixing ARM compiler warning. - Vacation extension: fixed handling of sendmail errors. It produced an additional confusing success message in case of error. - Removed header MIME-decoding to fix erroneous address parsing. Applies to address test and vacation command. - Fixed segfault bug in extension configuration, triggered when unknown extension is mentioned in sieve_extensions setting. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.3.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

You'd need to find out what exactly is locking those mailboxes for that long. It could simply be the user's client. Or I guess it could be LDA itself, or anything really.. Difficult to say. Difficult also to tell easy way to debug this.. Or when this happens does it happen to many people at the same time? Is the system load really high at that time then?

[Dovecot] Login via IMAP with MySQL as user database not working
by Chris Martin 13 Apr '11

13 Apr '11

Hello all, I am migrating from Postfix/Cyrus/MySQL mail server to a recently installed dovecot 1.2.8 on a QNAP TS259 NAS via XDove. I am unable to login via IMAP (the only method I've tried and the only method I want). I am using an almost identical database as the current existing Postfix/Cyrus/MySQL setup (with the except of paths). I have been attempting to get this working (off and on) for the past 5 months. During that time I have researched and researched, but have not found a solution. The Maildir has been copied from the existing server to the Dovecot server and have run the script 'courier-dovecot-migrate.pl', which was found at http://www.dovecot.org/tools/courier-dovecot-migrate.pl In a nutshell: If I have the password_query string in the SQL config file (shown below) set to return only 1 field, i.e. the password, then the Dovecot authtest app succeeds. But if more than 1 field is returned (i.e.: user and password) the test fails. And if testing with telnet I get the message of "* BYE Internal login failure. Refer to server log for more information.". The logs indicate that the password check returned OK but the userdb read appears to fail. If I change the userdb_query to return only 1 field (such as only the uid), then the logs show the correct value is returned, and yet the telnet login fails. So it seems that anytime there are multiple fields returned from the SQL query, the result is failure at that step (password check or userdb read). Therefore userdb prefetch never works. The NAS doesn't utilize a syslog so it's of no help in debugging. Below are the config files and samples from log files (scrubbed): dovecot.conf- (NOTE: the 'home = /tmp' in the plugin section is an attempt at rawlog from http://wiki2.dovecot.org/Debugging/Rawlog ... which doesn't seem to work) # 1.2.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.33.2 i686 log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log log_timestamp:
