Is the domain "rocketcom.co.uk" registered to you? Have you registered that domain? If not, the first thing you must do is register the domain. If you have already registered that domain then you will need to add it to your account in cPanel.I want to create an email address: mab@rocketcom.co.uk but the one that I am getting in cPanel is forced to end as mab@rocketcom.x10hosting.com. How can I get around this?
