Please help me stop this. Thank you!

Unless I'm mistaken (and I'm not the most knowledgeable person on
this list), I think your server thinks it's okay to accept mail for
the domain "exchange.net" (and I'm assuming "exchange.net" isn't
yours). So to fix this, you need to tell postfix only to accept
mail for your domains. I think you should check my_destination,
relay_domains, etc.
Post the output of "postconf -n".
-N.
Thanks for your reply.
mydestination = $myhostname
relay_domains = $mydestination
Actually its not just exchange.net, most of the mails are being sent
to bellsouth.net

I don't think you need $mydestination in relay_domains. And the rest
of postconf -n would still be useful.
