A bounce has an empty MAIL FROM, in other words "<>"

So if that is a valid address, they can set it up to reject mail from "<>" 
and they can use an alternate address for outgoing mail (possibly using 
SRS) so that valid bounces will get back to the sender, but bounces to the 
forged mail will get blocked.
