Once you have accepted the mail *YOU* are responsible for dealing with
it and generating bounced back to the original sender as per all the
RFCs. If you accept obvious forged mail then this is going to get you
sending bounced back to poor innocent forged recipients and listed as a
spam sender when you hit spam traps...
Just don't accept mail into postfix that you don't want to have to deal
with later... Kill it right at the front door and reject it and then it
becomes the upstream server's problem to deal with...
