Hehe... I was wondering where the link was in the first message. Anyway, I tested it out (I had to register on the site first) and it told me the host (me) DOES appear to accept messages for relay. Not good.
Ok, I still don't understand why I could not relay myself from my home PC. When I telnetted to port 25 of the server from home I couldn't do it and all the commands I entered resulted in 550 (unrecognized command) errors or no response at all. How did this website manage to get relaying to work when I couldn't? If anyone wants to try connecting to my relay, feel free. The outside IP address is 169.207.144.68. See if it works for you or not. Second, since relaying is obviously open... I need help figuring out how to turn it off. If anyone has experience configuring IIS SMTP let me know. It must be the settings within IIS but I'm not sure what to change without losing the ability to relay messages for whitnall.com (my domain). > Might help if I included the URL -- OOOOOPs! > > http://www.abuse.net/relay.html > > -----Original Message----- > From: STEVE BROOK=20 > Sent: Wednesday, November 21, 2001 2:25 PM > To: Exchange Discussions > Subject: RE: People using my IIS SMTP relay > > > Use this URL to setup an external test on your mail system.
