Thanks for the suggestion didn’t realize it worked with the top level domain as 
well as the prefix before the TLD. Does the order matter? Meaning should the:
From:us REJECT 
come before the “OK” lines?

Also where can I add a rejection for the hostname colocrossing.com when it 
appears in the relay line like this. 
v5CB8tYp022453: ruleset=check_mail,  relay=198-23-201-144-host.colocrossing.com 
[198.23.201.144] (may be forged), 

I tried:
colocrossing.comREJECT

But that doesn’t seem to work.

Sendmail access.db? It's easy:

From:us   REJECT
From:ci.boston.ma.us   OK
From:corunna.k12.mi.us  OK

Or name the states:

From:us REJECT
From:ma.us  OK
From:mi.us  OK

There was a pretty big thread about this suggesting to do this at the MTA 
level: https://lists.gt.net/spamassassin/users/198207/?page=1; 


What I’ve noticed is the *@*.us has picked up steam over the past couple of 
days. Since we use sendmail, it uses regular expressions and something called 
LOCAL_CONFIG and LOCAL_RULESETS macros, see 
http://www.xiitec.com/blog/2009/02/25/using-regular-expressions-in-sendmail/ 
 
but negative look aheads aren’t support (basic POSIX). I would like to block 
*@*.us but allow the cities and schools that use them so allow examples like 
@ci.boston.ma.us and corunna.k12.mi.us. I don’t think this can be done with the 
access.db file in sendmail.
