We´ve been joe-jobbed some time before, too. our solution was to set up
a badrcptpatterns file, which is provided by the spamcontrol patch. place a
´*@*´ in the file and include every user and alias on your machine with a
leading ´!´. that should deny every incoming mail except of those residing
on your machine.
as fas as i know that should help you out.
