Hallo James, Steve is right, your goal can be achieved at the firewall / router.
Also, Windows Server 2003 would have helped you with TCP/IP filtering. Assuming you can't or don't want to do either, your other option is to modify your receive connectors. EMC >> Server Config >> Hub / Edge Transport >> Receive Connectors In the Network tab you can set the "Receive mail from remote servers that have these IP addresses" setting. I hope this helps you in your quest for perfection. Regards, Andrew 2009/11/27 Steve Szabo <steve...@gmail.com> > James, > > > > You should be able to block it at your firewall.
