You should be able to configure this at the network level. Only allow inbound SMTP connections from 63.171.93.5 at their network firewall.

He was getting hundreds of spams per day. I changed his MX records to point to my server (Imail) priority 5, and his server as priority 10. My IMail server vets the email with SpamAssassin (http://www.visioncomm.net/sac) and if clean, forwards it to his Exchange, otherwise, it remains on my box for research purposes (via Webmail). The spam continued, and my server was NOT in the headers. I removed the MX record for Exchange. The spam continued, and my server was NOT in the headers. Does anybody know how to configure Exchange 2J not to accept inbound email unless the sending server IP is 63.171.93.5? I know veeeeeeerrrrry little about Exchange. It's in Native mode, but I couldn't even find the "About Box" to report the version<g>.
