IMAP: unread emails and mailbox full notifications

[Speedymik]

In Outlook Express there used to be a function to delete or "purge" deleted
messages. I used it every time I had read all the new messages because
otherwise they would reappear constantly as unread messages. The same was
true for mailbox full notifications. Is there any equivalent of this function
in windows mail, that I can use EVEN IF I DO NOT DELETE ANY MESSAGES?
