Is there a way to have control of the MX record for a domain? I have one domain that I need to direct to a Windows Exchange Server and so need MX record control on that one. Is this possible?

If you choose a shared hosting package then you will need to ask our support team to modify MX record entries for your domain name and make them point to your exchange server. 

If you wish to edit the MX record settings from your end then you will need to choose a reseller hosting package to control your DNS settings and MX record entries. Resellers get WHM access through which they can manage various functions for all accounts under their main primary account.
