So with Gmail's recent deployment of IMAP to various accounts, I've got a reason to use my Gmail account now. Since I don't want anyone able to read any of my mail (including google) I've setup my Gmail account to store encrypted backup copies of messages from my main mail accounts. My main mailserver is fine the way it is, and has rsnapshot backups of everything on another server, but just in case, some more transparent remote redundancy would be nice.
