[Dovecot] Possible to log IMAP connections to MySQL Table?
Is it currently possible to log all IMAP connection attempts to a MySQL table? Thanks.

Sure. You could use syslog-ng to log directly to a database or syslog plus SEC (http://kodu.neti.ee/~risto/sec/) to trigger insert rules.

If someone ever decides to make a log-login-tomysql plugin i would love to use it. I currently have a php script that runs during logrotate that parses the info.log for all pop3/imap logins and logs them to mysql, i only keep per minute and then i have a history table of peruser-perday for 90 days.
It would be way cool to have dovecot throw that to mysql automagically. If i were a c programmer i would do it myself =S
On our current mail system we've gone down the route of a PHP script as well for logging the connections. Since I use metalog for logging (instead of syslog-ng) and I don't really want to make an exception for one of our servers, I'll probably still have to use that script. I definitely want to put in a vote for the ability to log to an SQL backend though.

Somewhere on my hit list is customers wanting to see last access time for mailboxes and some informational IMAP/POP3 logging. If I ever get around to it, I could try making it a plugin rather than another rule in the fifo watcher.
Although I've never done any Dovecot development before, so if someone else does it first I wouldn't be hurt. ;)

Its definately valuable information, I like being able to look up a user to see their past logins and by type (pop3, imap) and be able to use this information to shut off or reduce quotas on seemingly dormant accounts, and helps to identify spam boxes. If i didnt have to run a php script it would be all the better, plus if i want information RIGHT NOW I have to remember to run the script before querying the current logins.

Or you can enable MySQL query log and see what's happening: http://dev.mysql.com/doc/refman/5.0/en/query-log.html

If you use MySQL for auth you could include some logging bits as part of your SQL query.

If you really want to log _all_ IMAP connections you could create a MySQL procedure that will log all interesting data you provide and finally returns the data for Dovecots password query. If you want to log only successful IMAP logins you should have a look at http://wiki.dovecot.org/PostLoginScripting

I'll take a look at the post login scripting. It sounds like it would be much better than a script that simply tails the log file for any IMAP connections. Thanks for the help!

I've started going down the path of the mail_executable script, but I've run into a snag. I have a script that works fine and inserts rows into the database as wanted, but whenever I restart the Dovecot service it inserts a row into the database with the USER variable set to "dump-capability" using the IMAP mail_executable. This doesn't happen with the pop3 mail_executable.
Below is my configuration for Dovecot 1.1.7. I'm assuming that the mail_executable(default) value is being run whenever Dovecot restarts. How do I prevent this from happening? Can I set the default to an empty string?

How about you just add a if ! [ $USER = dump-capability ]; then do
your stuff; fi
You could prevent Dovecot from calling it by manually setting
imap_capability setting, but I don't really recommend it since you'll
probably forget to update it when upgrading to a new Dovecot version..
I just barely finished adding that if statement before you replied. You're right though. Best not to play with the default for that. Thanks.

I used such script and it works fine (on not really busy site though):
I think you could use better way to find out if it's imap or pop3 (better than looking if $ENV{POP3_CLIENT_WORKAROUNDS} exists), but it works for me...
#!/usr/bin/perl use DBI; $db_user = 'dovecot'; $db_pass = 'DOVECOTPASSWORD'; $db_db = 'system';
$mode = exists $ENV{POP3_CLIENT_WORKAROUNDS} ? "pop3" : "imap"; $ip = $ENV{IP};
$u = $ENV{USER}; $virtual = $u =~ m/(.*)\@(.*)/ ? 1 : 0; if ($virtual) { $local = $1; $domain = $2;
$dbh = DBI->connect("DBI:mysql:$db_db", $db_user, $db_pass) || die "Could not connect to database: $DBI::errstr"; $dbh->do('UPDATE user set lastlogin=now(), lastlogin_ip=? where username=? and domain=?', undef, $ip, $local, $domain); $dbh->disconnect(); }
exec "/usr/local/libexec/dovecot/$mode";
