Can I make a very weak suggestion to look at that ZLIB compression extension I think you mentioned in the past?
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..
I don't think that SSL in general has compression enabled? Could be wrong, but I believe it's a option, but badly supported? I'm not an expert though so I don't know that for sure... I would be interested if someone had a recipe for enabling compression on TLS?
Personally, just as a data point, I use SS_H_ (dovecot --exec-mail imap) to connect to my imap host and enable compression using -C, which seems to have a good effect.
