Sure.  Use my Deliver program (currently at 2.0 patch 5; patch 6 out
soon).  Delivery files are shell scripts which control delivery of
each message.  A good one for filtering unwanted users is:

	:

	u="$1"
	from="`header -f from $HEADER`"

	# Kill mail from junk mail sources.
	case "$from" in
	*bozo@bozosite* ) echo DROP; exit ;;
	*kludge@hacksite* ) echo DROP; exit ;;
	esac

	# Oh goody, we keep it.
	echo "$u"

Deliver 2.0, at finer archive sites everywhere.

Not Just Another Deliver Hacker,
