While I can't speak to what Verizon is using, Both Exim and Postfix have the
very same feature called "address verification".  Its in use at a number of
ISPs.  My systems reject 1000's of messages every day because of
verification failures.

That would be 1000's of other people's servers getting traffic from you 
because someone forged their address in the spam. You are effectively 
doubleing the total load spam places on the net.

This doesn't scale.
