I do not respond about third-party howtos, setting up an OUTBOUND
mail relay is really simple.
- DO NOT list remote domains in relay_domains or virtual_alias_domains
or virtual_mailbox_domains or mydestination or transport_maps or
anywhere else on the outbound mail relay.
- DO list inside networks in mynetworks on the outbound mail relay.
- DO set relayhost (or equivalent) on the inside machines.
