Thanks. That solved the problem. Finally got rid of all duplicate items in sent folder. (Because of some mail clients not supporting disabling "Save a copy in sent folder when sending").

That means the message has had its "\Deleted" flag set, which is what the discard command does: https://tools.ietf.org/html/rfc6785#section-3.5 But the mailbox has not been "expunged". You probably want to set "imapsieve_expunge_discarded=yes"; see: https://github.com/dovecot/pigeonhole/blob/master/doc/plugins/imapsieve.txt#L125 -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/
