Since a long while, DO is blocking port 25 for email traffic. This, so email servers can’t use your VM as a direct mail relay. You can use port 587 & 465 for mailservers as well.

If this isn’t the case, please post some more information like;

  • Logs
  • Configurations
  • Errors (which you said isn’t there, but there should always be something, somewhere)

Hope this helps you
