We have SMTP Gateway installed on win2k3 to route all incoming and outgoing mail.  I enabled only one server which is our exch2k3 that has access to relay through that smtp server, but if I go to these websites: http://msv.dk/ms009.asp  and http://www.webcomindia.net/tools.htm test my server for relay, it relays one out of ten tries.  How can I stop this?  
I tried 3rd party products like mailsweeper, astaro and Symantec Mail Security for SMTP, all those products worked great for relay issue, but the price is too high.

Please help.

http://msv.dk/ms009.asp  website has a bug this is on their site

Known bug in this open relay check!
If your mail server in one of the 20 tests accepts mail for delivery,
this open relay check take this as an open relay, but it doesn't check that
the mail actually being delivered to nobody@msv.dk
Next version of open relay check takes notes of this
