What we do is run a perl script that parses the output of quota and sends email
to everyone over quota.  Our custom delivery program recognizes the from address
(our help desk) and sets the ignorequota option on the LMTP connection so the
mail is delivered regardless.

Even before we had that running, the users who were over quota noticed pretty
quickly they weren't getting mail and called the help desk :).
