Dovecot doesn't keep track of when flag changes have been done, so there's no simple way to say "expunge messages which have been marked as \Deleted after 7 days". With maildir you could check the file's ctime, but with mbox there's just no way.
We were toying with the idea of modding Dovecot to write an X-DeletedFlag-Changed-At header when deleting messages for exactly this reason. What's your thought on this idea, Timo?
