Please don't top post. If you don't know what that means, Google for it.

Yes, Postfix is a replacement for Sendmail.

You might want to rethink this bounce procedure that you are employing.
You are effectively creating 'backscatter' which will eventually get you
blacklisted. You are better off silently dropping those message.

It has been ages since I employed Sendmail. I thought though that there
was a way to create a list of valid users and discard the rest.
