The thought has never occurred to me - I really should back up my email. My ISP keeps the last three months of messages on the server, but older stuff - if I install OS X, I'll lose it. Is there a handy-dandy utility that will do this? Where are the files kept? I'm learning AppleScript out of boredom and could probably throw together a script to back it up, but I'd need to know what the files were. TIA
