I am setting my first customer that is hosting ONLY email with me. All other accounts I've setup in the past have hosted both their website and their email. The customer is a bank and I don't have access to change any of their DNS setup. I was wondering what I need to do to setup the account on my dathorn account. I am concerned about the fact that the WHM is going to create A records as well as the MX record I need. Do I need to delete the other records form my dathorn DNS zone, or just leave them alone. Additionally, what info do I need to give the people that are currently controlling the DNS zone for the customer's website AND email. I just need them to create an MX record entry for cpanel27, right?
