Please don't do this. If the mail is spam, there's a high probability
that the reply addresses are bogus too, and you're spamming an innocent
third party. By doing that you're making yourself part of the _problem_
rather than part of the solution.
Also, autoreplies should be sent to $sender_address, not to any other
address. It looks like your setup is responding to bounces, which it
absolutely must not do. If I encountered this in the wild I'd be
reporting it as network abuse.
If you want to do this kind of thing, then do it with a 'fakereject' at
ACL time. The SMTP error will cause a spammer to silently drop the mail
and move on to the next victim, while a _legitimate_ mail will trigger a
bounce to be generated by the MTA which was trying to deliver it to you.
