We have SMTP Gateway installed on win2k3 to route all incoming and outgoing mail. &nbsp;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: <a href="http://msv.dk/ms009.asp" rel="ugc">http://msv.dk/ms009.asp</a>&nbsp; and <a href="http://www.webcomindia.net/tools.htm" rel="ugc">http://www.webcomindia.net/tools.htm</a>&nbsp;test my server for relay, it relays one out of ten tries. &nbsp;How can I stop this? &nbsp;<br />
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.<br />
<br />
Please help.
