Here is the setup. I have a web server on a DMZ that I am trying to send email from an app. I have the IP of the DMZ server in a receive connector set up to allow anonymous users to connect. When I try to test connectivity to the remote mail server using"telnet mail.domain.com 25" the session is blank. When I test from my workstation I connect and can see commands when I type ehlo. I have a couple of other receive connectors for various situations and I have tested on them but I am unsuccessful.
Ideas?
