No I intend to use the MAIL FROM domain. That is assuming that the AV gateway
preserves it.

Why would it obviously match? Take your email headers I just received. If I
had
"apex.listbox.com" as my gateway machine. I could search down, find the

by apex.listbox.com (Postfix) with ESMTP id 144B055773 for

extract your IP address - 193.11.88.60
and then use it to check the SPF record.
So are you proposing to check the SPF record of the From:domain against all the
Received:
headers IP's until you find a match? What about the ReplyTo and the Return-Path
headers?
That is potentially going to be one seriously long and messing series of checks
