The record that specifies the mail servers that handle email for your domain is a (Mail Exchange) MX record. It is a part of the several other network records which define where a particular domain name will resolve from. . By default, all of the email for your domain is handled by Dotnoc’s mail server. You can, however, choose to have another mail server handle your email. You can select a mail server such as Register.com or you can specify an Exchange, Novell or other in-house mail server. If your organization has multiple mail servers (such as a primary and secondary server) you can specify multiple IP addresses and set the priority for each.
