  How about running:  $MAILBIN/policy-builder.sh -n   ?
  "policy rejection" is a give-away for need of it.

	This means the message got thru, and smtp transport agent is
	trying to deliver it, but MX data after 'self pruning' is
	an empty set, and no A record is present.  A symptom that
	'localnames' does not list 'something.baz.org' in it.

	(With an A record the message could have been:
	 "Trying to talk with myself !")
