So SN Mail has been driving me mad for days now. It won't send from MobileMe, and won't receive for Gmail! I've no idea what to do, short of a reinstall (SN has hosed all of my computers - each in a different way, so maybe it's a good idea to downgrade... ). However, I'd rather not wipe my drive, and am hoping there's some plist I can delete or something that'll make it all better. Ideas?
