I'm working on a fix for 
http://bugzilla.mozilla.org/show_bug.cgi?id=38954 (Automatic 
notification of unread(new) mail in all IMAP folders). This will be my 
first contribution to Mozilla, and I'd like for somebody familiar with 
mailnews and IMAP to take a look at what I've done, to see if I'm on the 
right track.
