In a cooperative agreement with my ISP, I have set up a SIMS server to be a spam 
filter for his domain. His ancient Netscape mail server has no anti-spam features.

We call the new, spam-filtering host smtp.domain.com (where domain.com is his domain).

His normal mail host is mail.domain.com so, I put in the router:

 domain.com = mail.domain.com

He then assigned a higher priority to smtp.domain.com than to mail.domain.com. Most 
incoming mail should now seek out smtp.domain.com instead of mail.domain.com.

All of the anti-spam features, RBL, blacklist, etc. will be applied to his incoming 
email and the good stuff, non-spam, will be passed on to mail.domain.com by the router 
entry "domain.com = mail.domain.com".

The problem is that since, I can't "Relay for Clients Only", I obviously need another 
router entry to handle all the spam that they attempt to relay through this open relay 
I have created.

Anything that is not handled by the "domain.com = mail.domain.com" entry needs to be 
rejected. What do I put at the end of the router to reject everything else? 

* = error

?
