Well they could do that sending to ANYONE pretty much, eh?
Mail delivery for system accounts should be eliminated via the
qmail-users(5) mechanism. Ideally it would be nice for there to be a
control file -- perhaps ``badrcptto'' -- to reject mail for such users at
the door.
Heh.. maybe there's already something like that and I haven't seen it. ;-)
