Thanks for this, Alex... sometimes in panic mode you forget the obvious.
I was able to find something unique across all messages, and there was
something inserted by their MSExchange server (thread id) that was
constant, and I added it as follows to /etc/postfix/header_checks
/thread-index: AcfQVR+P5JkcCC8rQ4GAyZsYZ1xAcA==/ REJECT Misbehaving MTA
Thanks to all replies.
