Hi guys, One of my friends has just seen all of her emails in OSX 'Mail' disappear from before January 6th 2010 all the way back to when she first got her mac 4 years ago. I suggested it might be possible that she has some kind of feature on which compresses and backs up all of her emails from a certain date? Is that a feature of OSX 'Mail'? (I don't use the app) She does have Time Machine installed and backing up her stuff - do you guys know whether Time Machine also backs up OSX Mail? Thanks!
