We used to use Netscape's mail server back when it was free for educational
use. At the time, we did have a closed relay system, but since our server
wouldn't respond with a 550, we got blacklisted. It took us quite a lot of
effort to get the various Anti-relay sites to accept that we were a closed
relay.

Those aren't holes. One can legitimately accept mail for those addresses and
as long as it isn't relayed to the final destination the server is relay
secure. The designers of those tests have implemented their testing criteria
improperly.

Subject: Open Relay Suggestions
I am using Interscan Virus wall as my incoming smtp server on port 25; which
then forwards my mail to the Exchange IMC on port 6000. I have been testing
against open relay testers and I always fail the one or two tests where they
spam my domain name. I am assuming this is because Interscan cannot look up
usernames to see if the mailbox is valid? For that matter I dont think
Exchange 5.5's IMC does either?
Anyway to close this last hole? Suggestions? I worked hard to get off all
the RBL's the last mail admin had gotten us on . . .
