Use the firewall/gateway example in http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall to configure the domain as a relay domain. Use virtual_alias_maps (NOT VIRTUAL ALIAS DOMAINS) to deliver some addresses locally. See http://www.postfix.org/STANDARD_CONFIGURATION_README.html#some_local Wietse
