On the gateway I have: mynetworks = 127.0.0.0/8 10.0.132.0/24 All mail servers on my LAN are in that range. On the inside machines I have: relayhost = [10.0.132.15] and that is the IP of my Postfix mail gateway. Do I need to add the google mail servers to that relayhost? I still want all mail not destined to a user on my domain to go out through my mail gateway and only mail to a user in my domain managed at google apps to relay through google mail servers.
