i had a similar problem with my open relay (setup for the convenience of my
own users) back in college. here was what i did:
* FEATURE(access_db, hash -o /etc/mail/access)
* FEATURE(rbl)
I'm sure it's pretty outdated, so I went to sendmail.org and found:
anti-relaying page:
http://www.sendmail.org/tips/relaying.html
anti-spam cfg control:
http://www.sendmail.org/m4/anti_spam.html
hope this helps!
