   This is just not true.  Action_bounce will simply return an SMTP
reject.  Only if the sending MTA tries to bounce the message will a
(usually faked) sender receive a bogus return.  In the case of SoBig, the
infected PC ties to contact the addressee's MX directly.  If, for example,
they contact my email relay, they get a 5XX return and that's it.  I have
never heard evidence that the infected PC will then turn around and send a
bogus return to the faked sender address.
