Ok, I believe we have narrowed it down :) Thanks for bearing with us 
folks :)

So what we are addressing is the valid return path. The current 
standards allow for invalid return addresses, which is the one of the 
root problems that led to spam. This has a side-effect of allowing 
anonymous email (which can still survive if the anonymous email server 
uses its own email address for MAIL FROM). That I believe is our point 
of contention, and I would be more than happy to see the exact section 
which requires all mail to be returnable.
