OK - one note - I was using TLS, and it has to be IMAPS.  (I noticed  
the wrong port being used in the wireshark captures.)  At least now it  
shows up in the folder list as expandable, even if I'm not getting any  
real content yet.  I'm also now seeing some imap debug output, when  
there was none before.
