    It looks like you have connection problems try this command nc -zv 209.85.201.26 25 if it times out then you are being blocked by DO.

    Also make sure to use latest LTS version from ubuntu that is Ubuntu 16.04, 17.04 will end its life in three months from now.

  • hi Mohsen.

HI

finally i made a ticket to DO, they said they will consider to open port 25 after 60 days i create new droplet, cuz they worry about spam problem.... so i agree with them. From now i just wait for a couple weeks ahead.
