IMSP and Digest-MD5

Howdy Cyrus,

Funny. I saw that in the IMSP server sources and didn't even twig that it 
was "imap" instead of "imsp", otherwise I would have modified the server 

Wouldn't it be better if this were filed as a bug with CMU and get the 
service name changed in the server sources? That, to me, would seem to be 
the better way to handle this going forward, since imap and imsp are two 
different services.

Thanks for the help!
