Adding a Mail Exchanger (MX) record

A Mail Exchanger (MX) record specifies a mail server for the domain other than the SMTP server provided by Ensim Pro. You can designate more than one external mail server for the domain.

- Note: Add a Host (A) record for the host running your mail server before you create the MX record pointing to it.
  However, if you are not using Ensim Pro as your DNS name server, you do not need to do anything with the MX records in Ensim Pro; the settings shown in the Appliance Administrator GUI are not used. For more information, see:
  Introduction to DNS and name servers
  Using Ensim Pro as a DNS server

To add an MX record:

1. In the shortcuts section of the Home page
   , click Zones (DNS section).

2. In the Zone List form, locate the zone you want to add a record to, and in the Actions column, click . The Host List form opens. It displays all existing records for the zone.

3. In the Add: Record area, click the arrow and choose Mail Exchanger (MX) Record. The Add Mail Exchanger (MX) Record form opens.

4. Optional: In the Mail Domain field, enter the name of the subdomain this mail server will serve; for example, Mall.acme.east.com.

5. In the Mail Server field, enter the name of the mail server that will serve your domain.

6. Optional: If you are designating more than one external mail server for the domain, use the Delivery Precedence field to set the delivery priority among the mail servers.

7. Note: The lower the number in this field, the higher the priority. For example, if you have two mail servers, you could assign a delivery priority of 3 to one server and 4 to the other. Mail would be delivered to the precedent 3 mail server first. If delivery fails there, it would be delivered to the precedent 4 mail server.

7. Click Add.
