Well...how embarrassing! Ok..THAT problem is closer to being solved. So
now a followup
: There is still one domain, ms[somenumber].hinet.net that courier
still accepts and delivers email for. I have no idea who they are. I
notice that the smptaccess files usually take IP addys, but can they
also take named domains? In other words can I do:
*.hinet.net deny
and have it work?
Thanks!

Sounds horribly like spammers are succeeding in using you as a relay!
Courier, out of the box, doesn't relay mail. You have to add an entry
to (a file in) smtpaccess, specifying the IP addresses that are allowed
to use you as a relay, for example
a.b.c/n allow,RELAYCLIENT
Hope you haven't got RELAYCLIENT for all addresses!
If you /have/ to allow relaying from any address, perhaps because you
have roaming users, then you posilutely must require authentication!
Absotively!
