  • Check with your ISP to see if you are authorized to relay mail through their servers.

  • If the server does allow relaying, make sure that your IP address is authorized to relay mail.

If you have checked all of these things and you are still getting the error message, then you may need to contact the administrator of the server you are trying to connect to for help.
