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.
