I have a client site currently on a Hostgator reseller account but I'd like to move the website hosting over to my Linode. The email accounts however should stay with Hostgator. DNS is also managed with Hostgator. In the " Simple DNS Zone Editor" of the Hostgator CPanel I have the option to add an A Record or a CName record.
In which of the two do I need to enter my Linode IP, and will their emails continue to function fine on Hostgator? Is this all I need to do?
