postfix-users: transport vs. relayhost

transport vs. relayhost

Let me take a step back. Let us say that my looks like this:

# i don't do local delivery on this machine, so:
mydestination =
relayhost =
transport_map = hash:/etc/postfix/transport

and transport looks like this: smtp:[]

If I send mail to, transport shouldn't
get involved, right? Or, maybe the map is consulted but
since there's nothing for in there, it doesn't
act on it. The transport_map parameter doesn't
turn off relayhost entirely, does it? 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?
