Howdy,
Since so many people asked me for the SPam prevention rulesets, I
will post them to the list, and hopefully they will be of much use to
freebsd-ers out there.
A couple of things:
1. Do this at your own risk
2. You need Sendmail 8.8.7 (see www.sendmail.org)
3. Backup sendmail.cf (cp /etc/sendmail/cf /etc/sendmail/cf.bak2)
(the 2 is included as you may already have a .bak file)
4. create /etc/LocalIP with all your address blocks in there ie
/etc/LocalIP
201.15.1
203.24.24.1
{Will allow any host 201.15.1.xxx to relay and also the specific host
203.24.24.1.}
5. create /etc/relayto allowing any remote host that uses you as a
relay.
6. append tosend to the endof sendmail.cf (cat tosend >> /etc/sendmail.cf)
7. restart sendmail (sendmail -bd -q30m)
8. Test it out
Hope this helps....
Regards,
Stavros Patiniotis
