while WHM gives you a fun menu item to change the hostname, be warned, it does not always work right…  After putting in your new host name you might geta message about adding a A record and once you hit ok you might then get a BAD LICENSE FILE or similar massage….  do not fear, there is a solution

run   /usr/local/cpanel/cpkeyclt

 This will correct the license, but then go hit the menu item to add a A record to the DNS, even though it asked you before if you wanted one, it might not have created the needed entry. Without a correct entry, most email spam filters will kill your emails for not having a valid domain.
