Adding a Mail Exchanger (MX) record

An MX record is an entry in the DNS zone file that specifies the mail server responsible for processing the email for a domain.

To add a Mail Exchanger (MX) record:

  1. On the site administrator Home page, in the Microsoft DNS area, click list zones. The List of DNS Zones page opens and displays a list of DNS zones for the site.

  2. On the DNS zones list page, select the zone for which you want to add the MX record, then click list records. The List Records page opens and displays a list of existing DNS records for the selected zone.

  3. On the list records page, click add mx record.

  4. In the mail domain text box, enter the host name of the domain. The current domain name (displayed next to the text box) is appended to the host name.

  5. In the mail server text box, enter the fully qualified domain name of the mail server that will map to the specified domain name.

  6. Note: Do not enter any alias (CNAME) names in the mail server text box. Ensure that a corresponding host name (A) record exists for the host name specified in the MX record.

  1. In the mail server priority text box, enter a number to designate mail priority among mail servers. The lower the number in the mail server priority field, the higher the priority. If there are two mail servers with the same priority, one of them is randomly chosen. The value of this field should be between 0 and 65,535.

  2. Click add.

The List of DNS Records page displays the new record.
