  Hey there! Are you able to send a message to the user on server2 from another email account that isn't on server1, such as a Gmail address?

  hi Guys external emails such as gmail, hotmail, etc. Yes, they can send messages to users of server1 and server2 works correctly The only problem is communication between mail users, server1 and server2 Likewise, sending emails from server2 to server1 have the same problem

  I would ensure that both machines have the correct option selected in cPanel >> Email Routing, as you can run into this problem if that isn't properly configured.
