Actually, that's not a bounce you site below.. that's a reject. Technically
bounces happen after the message has been accepted.

In general, what you want to do is a MTA thing, in your case postfix.

MailScanner acts only after the message has been completely received and
accepted by your MTA, so it could not do what you're doing here.

MailScanner could generate a post-delivery bounce message, but that's a Bad
Idea. (You can get blacklisted by SpamCop for this kind of crud, so I'd advise
against doing it intentionally.)

Unfortunately, I'm not a postfix expert, so I don't know how to configure it to
do this.
