I set my Exchange server to trust my IP address as specified here: http://serverfault.com/a/207583/101328 (Allows my ip, no authentication, set to "Externally Secure")
However, it still does not work! The following occurs:
Server: 220 server.mydomain.com Microsoft ESMTP MAIL Service ready at Thu, 1 Dec 2011 19:26:23 -0500 //This actually has my ip address, not x's MyClient: HELO [xxx.xxx.xxx.xxx]
And then my client just hangs forever. Any idea what's wrong and what I can do to fix this?
I'm connecting to the exchange server on port 25.
