That's not a bounce at all, that's a reject.
Bounce != Reject
MTA accepts the inbound mail only to find it can't be delivered. MTA
therefore generates a DSN saying that the mail couldn't be delivered and
shoots it off to the address in the SMTP envelope "from" (often inserted
in the "Return-Path:" header).
MTA realises that the mail won't be deliverable *BEFORE* accepting it.
MTA therefore says "I don't want this" instead of "Mail accepted" and
the delivery is aborted right there and then. Dealing with the mail
becomes the upstream MTA's problem.
Bounce == abuse of the Internet because of the overwhelming proportion
of mail sent "from" forged addresses.
Reject == The Right Thing (tm)
You used the word "bounce", not "reject". Therefore, anyone here who
knows the difference between "bounce" and "reject" is going to think
you're advocating abuse of the Internet by suggesting that undeliverable
mail be force-fed to the unsuspecting netizens whose e-mail addresses
were forged into the spam.
