I see....

In that case it sounds as if your MTA isn't properly configured to prevent "relaying". 

I don't use Postfix, but maybe this link will help you to check your configuration to
prevent unauthorized relaying.  Also, it seems your host is being marked as sending
SPAM and that you'll have to request it to be dropped from the list of the various
organizations that have flagged your host.

http://www.postfix.org/SMTPD_ACCESS_README.html   may help....

Or, wait for someone that knows Postfix to give you a better answer.
