You were clear. I understood that this was caveat emptor and that store
- forward was the better way to go.

Admittedly it is possible to configure a degenerate installation

Excellent advice, and I will read these throughly.
Note, I am not advocating this, just noting it is possible. Even
with this, you still don't see the original client IP address as
the origin of the SMTP connection at the backend MTA.
Postfix sends XFORWARD metadata, but I don't think Microsoft Exchange
supports this.
You can use a proxy Postfix if you know what you're doing, but likely
you should stick to store/forward.
