I'm running through the e-mail gateway example at postfix.org as this appears to be what I'm looking for, a setup which passes e-mail on for valid domains.
It talks about using transport_map and defining the inside smtp gateway... My knowledge on proper handling of this is pretty dicey but as I understand it the second, third, fourth MX servers etc. should pass e-mail to the first MX server which then relays it to the internal mail servers. Assuming this is correct, should I be defining this setting at all?
