Let me take a step back. Let us say that my main.cf looks like this: # i don't do local delivery on this machine, so: mydestination = # relayhost = outgo.arlut.utexas.edu transport_map = hash:/etc/postfix/transport
and transport looks like this: blarg.arlut.utexas.edu smtp:[blarg.arlut.utexas.edu] If I send mail to some...@example.com, transport shouldn't get involved, right? Or, maybe the map is consulted but since there's nothing for example.com in there, it doesn't act on it. The transport_map parameter doesn't turn off relayhost entirely, does it? example.com should honor relayhost's value. Right? Don't confuse this with my earlier post. I'm investigating that as well. But everything I read doesn't directly address the above question. Am I to understand that transport_map=value existing at all means relayhost=value is ignored? Because that doesn't seem natural to me. Relayhost ought to be honored when the transport_map is irrelevant -- well, that's what I've been expecting. Is that part of what I'm doing wrong? j. -- Jay Scott 512-835-3553 g...@arlut.utexas.edu Head of Sun Support, Sr. System Administrator Applied Research Labs, Computer Science Div.
