[MlMt] duplicate messages

[Steven M. Bellovin]

I just started seeing duplicate messages appearing in some folders.  
Possibly significantly, all of them are sorted by a MailMate rule to a 
folder that is included in a smart folder; this smart folder selects 
unread messages in a subset of my folders.  When I log into the IMAP 
server, I see identical messages there, so MailMate is displaying things 
properly, but I'm wonder if there was some chance recently that would 
make it fetch such messages twice.  I'm running Version 2.0BETA (6069).
