Does anybody have recent experience with the Cyrus IMAP Server from 
Carnegie Mellon?  I tinkered with this a year or so ago, brought it 
up on a demo system.  At the time, it was very functional but the "team" 
decided it wasn't quite ready for prime time.

We're looking at it again and are curious to know if anybody else is using 
it in a production environment.  The feature that is very interesting is 
that it isolates email user accounts from system logins (system accounts 
are NOT mail accounts).
