I’m going to make a guess that you don’t want MAIB to do all your DNS work. It’s easier to make MailInaBox your domain server and make that your traffic redirection point. Then in your DNS settings at your domain name host you can make the name servers your box.
@sugumaranv correct me if I’m wrong…it should be possible to redirect the mail server parts of the domain using MX to point to the box instance? I haven’t tried it this way, but I would assume you could do it this way and not make the mailinabox your central controller for all the dns things of that domain.
I think this is what @aton85 is asking.
