windows mail catch up imap new mail notification

Hi everyone,
I'd like to see a "Catch up" or "Mark folder read" for regular IMAP-folders - not just for newsgroups. Usually I empty my "Junk mail" folder only once a month or so... And the unread messages in that folder stack up. A right click "Catch up" would be really convenient...

Since the OE6 days I have this problem: Whenever Widows Mail (=OE6.1) sends/receives mails it finds that I have "new email". But that's just not true. When I check the folders I cannot find a single unread message. It seems to be a problem with my IMAP server (Mercury32) because OE redownloads 6 emails over and over again every time during send/receive. Maybe fix that or just don't display "You have new e-mail" when all mails are read already.

Comments?

Regards, Simon
