Alas. These days, when just about everybody sends mail in HTML format, 
it is customary to send HUGE .doc files back and forth and nobody ever 
deletes any old mail, it is not that uncommon.

Just an example from our mail server (ca 300 users):

root@data2:/data# du -h --max-depth=1 | grep MAIL
21G     ./MAIL
