Just to clarify is this something that is not built into postfix with my current use case? i.e because the postfix server is not authenticating users it's just a relayhost? If I made users authenticate against the postfix server first should options such as reject_sender_login_mismatch do what I am trying to achieve? Has anyone utilised header_checks do check for patterns? Thanks
