No idea how you'd do this, but I'd like to suggest that you don't.
Because just how many spammers include legitimate headers anyway?
IANASA, (I am not a sys admin) but I know I've had my fair share of both
bounces and angry e-mails when someone has spammed someone else using
one a forged sender of my old adresses, and I don't think it does much
good bouncing spam.
If it goes back to the spammer, they might be able to discern between
legit and manufactured bounces (confirming your adress) or attain more
information about the route the e-mail has taken, and help them abuse
it. Not good. If it doesn't find its way back to the spammer, it just
means more junk mail flowing thru the wires, bothering innocent bystanders.
Now, if you're working on a method of tracing those spammers and
stabbing them in the eye with a fork, I'd say knock yourself out. :)
Just my 0.02 NOK.
