[nflug] Postfix Store and Forward

[Eric Toczek]

Did you run postmap /etc/postfix/transport to create the hash map? I
forgot to mention that. What its doing now is not reading the
transport map, so it will try to relay that mail to the mx, which is
itself.
If the map is created right, on startup postfix should log that it is
reading in a transport map.
