We have a DEC Alpha workstation running Compaq's TruUNIX64 (better known as MAIL01) with sendmail 8.9. This machine accepts any incoming mail, checks it against ordb.org, rfc-ignorant.org, and osirusoft.org for any RBL entries. If it finds any RBL violations, it ignores the message. If it gets past the spam filter, it passes it to our MS Exchange server. Exchange will only relay mail for one device that sends alerts to our engineers' pagers when there is a problem on her/his system. We're not an open relay, however, when someone tries to relay mail through MAIL01, it passes it off to exchange, which then basically eats the message because its not inbound for mydomain.com or myotherdomain.com.
This works reasonably well to prevent relaying. But how can we configure sendmail on MAIL01 to only accept inbound messages for mydomain.com and myotherdomain.com, yet force it to do the RBL scan, and then relay it to Exchange?

I've done more R5 deployments than I care to think about.
