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..
Anyway, just a thought - I'm assuming that the probable implementation is going to be fairly simple. I would think that zlib and/or lzo would be good compressors if there is a choice of implementations? Certainly LZO would be a good choice for faster 100mbit connections
http://www.ietf.org/rfc/rfc4978.txt specifies DEFLATE format that can be implemented using zlib.
