Isn't your border router set up block source/destination addresses with RFC1918 ip's? >claims his email address is [EMAIL PROTECTED] (which lets say is a VALID >address), now he sends mail and it hits my gateway box and then forwards >the mail to my Real Imail Server Which Sees the IP as my Gateway not the >IP where the Email was Sent >from, so the mail goes to my users, hence an open relay if he knows one of >my users Email Address.
