  Are you able to connect server 1 from server 2 via ssh? Try pinging the server1 from server2. You can also use telnet to verify that server2 is able to connect server1's mail server. One more thing you can try is whitelist server 2's IP in server 1's firewall.

  Hi, H=DOMAIN.com [IP] Network is unreachable --> Are you able to get a ping response from the domain you are connecting from your server # ping domain.com # telnet domain.com 26 # telnet domain.com 587 Check the above command and if the connection is made or not..

  machine 1 send emails to machine 2 but not the opposite, i have firewall up on both and port 25 if open as i can send from both machines to gmail or hotmail and receive.

  
  Hello, You can access SSH as root on "Machine 2" and run the following command:
  telnet "machine 1 IP Address" 25
  Is the connection working as expected? Thank you.
