> what's RBL ?
MAPS RBL, Mail Abuse Prevention System - Realtime Blackhole List.
It's a system from creating intentional network outages for the purpose of
limiting spam mail. Basically, they keep a DB of systems which are known
to be spammers-friendly, keep an open relay, etc ..
There are rules (The sysadmin needs to activate them --- It's not forced
on anyone), which check every incoming mail for an entry in the RBL
system, and refuses to accept / talk to the remote host if it exists.
Basically, getting RBLed means that a great deal of sites on the network
will stop talking to you.

Your network --- Your problem, but having your smtp server accessible from
the net, and having it relaying for everyone is something which cannot be
justified - In my humble opinion, at least. (Well, I also took that
opinion from Paul Vixie, so it's not so humble)

The best advice I can give you is to get 8.9.3 (Or consider moving to
Postfix / qmail), and recompile / reconfigure it using a brand new M4
file. And start debugging from there ...
I wouldn't use any sendmail the distribution supplied in a live server.
