iirc, esmtp AUTH has to take place before any data is sent, so it would 
come in before the MAIL FROM.

What you could do is use a courierfilter to check the details. You're 
better off checking the From: header as well, as I can set MAIL FROM: 
<blas@fsj.com> and claim the From: of any address. If you can't find 
the AUTH= in the top Received: header, drop the message.
