Dear everyone,
I am trying to install a DirectAdmin panel on my server, it is going well, but the mail server does not want to cooperate yet. I get this message all the time.

I keep thinking I'm doing something wrong, but I don't know what. Can someone help me out? What does it have to do with?
I hope for your answers soon.
Yours sincerely,
Bradley
