Its copied twice to Spam...its not in the INBOX any longer.  Well...the 
duplicates were not a problem before when using courier-imap (though on 
a different server).  I'm not too terribly concerned with the issue any 
longer, as the issue could very much considered client side.  Thanks for 
the help!  If you do have any other suggestions (or if anyone else does) 
on fixing the issue, I'd still like to know.
