Well, RMX could be used to verify the From: address as well.
Feel free to ask your MTA to do another RMX lookup after 
receiving the message body (and before sending the reply code).
If you like it, you can do it.

My point is not, that RMX would not be able to provide that
kind of security. It could. 

My point is that this kind of security is something you certainly
do not really want to have in some cases. But if you really want,
feel free to use it for the From: address.
