Here's the documentation for a basic frontend mail gateway http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall Generally speaking, - the domains postfix will relay are listed in relay_domains. http://www.postfix.org/postconf.5.html#relay_domains - the valid recipients are listed in relay_recipient_maps. http://www.postfix.org/postconf.5.html#relay_recipient_maps http://www.postfix.org/ADDRESS_CLASS_README.html#relay_domain_class or if a list of valid recipients is not available, use recipient address validation http://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient - use transport_maps to tell postfix the next-hop server. http://www.postfix.org/postconf.5.html#transport_maps -- Noel Jones
