It would have to be done by proxying in imap-login similar to how SSL  
connections are handled. But aren't you using SSL already, and why  
not? Using that would give compression for free. Although I haven't  
really looked at if it's already automatically enabled or if I or  
clients should do something special..

http://www.ietf.org/rfc/rfc4978.txt specifies DEFLATE format that can  
be implemented using zlib.
