What a fool, ! Appologies for the incorrect previous explanation and many thanks for the reply pointing out my mistake :)
point 4 previous should have referenced Postfix1 My goal is if possible I'd like to have an independant server (the gateway) wash all mail whether internal or external before any final delivery takes place. The mail flow should read as follows: - external mail recieved into MX @ VSgate1 - hits VSgate1, and is washed for spam and virus - washed mail is sent to Postfix1 for delivery processing - Internal senders any mail sent by an internal user should first be sent to host VSgate1 to be washed and then returned via VSgate1 to Postfix1 for delivery. Therefore internal and external mail is hopefully washed by the gateway server before any internal or external delivery.
