OK - I can confirm this happens, but ONLY if the master IMAP server  
goes down and IMP can continue to connect to an imapproxy server.

The problem is that the IMAP client object does not fully reset itself  
when attempting to re-authenticate.  As a (convoluted) result, the  
internal cached capability array becomes empty without any ability to  
re-populate this data once the IMAP server can be authenticated to  
again.

Solution is to properly reset internal values to prevent this caching.
