Hi I wonder if it is possible in postfix client to enforce usage of TLS based on sender. Just like in smtp_tls_policy_maps but based on sender of the message and not on rcpt or nexthop. The only way I can see so far is to setup another postfix instance with smtp_tls_security_level = encrypt and use a sender dependent relayhost map on the sending system to forward the messages from the sender in question to that new postfix instance. Or would it be possible to use a sender_dependent_relayhost_maps and define just the transport ex smtps: (without nexthop) in there so postfix would use that transport (to be defined in master.cf) and the normal MX of recipient domain?
