+"""Incoming queue runner.
+
+This runner's sole purpose in life is to decide the disposition of the
+message.  It can either be accepted for delivery, rejected (i.e. bounced),
+held for moderator approval, or discarded.
+
+When accepted, the message is forwarded on to the `prep queue` where it is
+prepared for delivery.  Rejections, discards, and holds are processed
+immediately.
