That said, better yet is to configure your system so that messages
to over-quota mailboxes bounce immediately, rather than tempfail.
Then there are no delays and the sender receives a timely bounce.
Many sites configure an access(5) table that lists over-quota
users, so that the mail is never accepted in the first place,
the bounce is generated by the sending system.
