If the expire plugin is enabled and a new message (not in trash) is
deleted via IMAP in Mozilla Thunderbird (only tested in this client), it
will indefinately copy the message into the folder. Dovecot, meanwhile,
occupies itself with this:

I tried using a "user_field = user" additionally as is written here:
http://wiki.dovecot.org/Plugins/Expire. (Incidentally, there must be
some mismatch in the documentation because the tables for v1.1 do not
contain a field username). Of course I adapted the MySQL database
accordingly.
Unfortunately I was unable to produce a backtrace.
Thanks,
