I made small debug session with dovecot. During this session one message
was received and filtered to Lists/gtk folder. Same message is still in
Inbox folder but marked as read (not touched by me).

Following log was generated with dovecot rawlog utility[1]:

I suppose no messages was marked as deleted so expunge does not help to
keep my inbox clean from already filtered messages.
