I was tasked to mark all messages coming from unauthenticated clients

Best practice when requirements get complicated is to divide and
conquer. Use a separate dedicated machine (or dedicated public
IP address) for inbound mail with a separate Postfix instance
handling only inbound mail.
Outbound email is then handled by a separate machine or Postfix
instance.
Yeah, this is the solution we proposed to our customer: point the MX
record to a new machine for subject rewrite, keeping the actual
mailserver for authenticated send/receive only.
But I was also interested in a single server solution, not least to
better understand postfix itself.
Thanks and regards.
