Adding/Removing Mail Delivery Servers

On the Configuration > Routing > Mail Delivery Servers page, specify the internal mail servers that receive incoming mail from the Email Appliance.

You can add a single mail delivery server, add a group of mail delivery servers, and remove mail delivery servers or server groups.

  • To add a single mail delivery server:
    1. Click Add.

      The Add Mail Delivery Servers dialog box is displayed.

    2. From the drop-down list, select Add a single mail delivery server.
    3. In the Description text box, enter a name or something else that helps you to identify the mail server.
    4. In the Address text box, enter the fully qualified hostname or IP address of the mail delivery server.
    5. In the Port text box, enter the port on which the server is listening for SMTP connections.
    6. From the DNS type drop-down list, select The type of DNS record used to lookup the host (A or MX record).
      Note
      DNS A records are used for looking up hosts for most types of network connections (HTTP, FTP, etc). DNS MX records are used specifically for email routing and can be used to specify multiple hosts (for example, for failover or load balancing). If the mail delivery server does not have an MX record in DNS, set the DNS Type to A.
    7. Click OK.

      The new server information is displayed in the Mail delivery servers table.

  • To add a mail delivery server group:
    1. Click Add.

      The Add Mail Delivery Servers dialog box is displayed.

    2. From the drop-down list, select Add a mail delivery server group.
    3. In the Description text box, enter a name or something else that helps you to identify the mail server.
    4. In the Port text box, enter the port on which the servers are listening for SMTP connections.
    5. In the Address text box, enter the fully qualified hostname or IP address of the mail delivery server. All mail delivery server groups use MX records.
    6. From the Priority drop-down list, assign a value for the server. The lower the number the higher the priority. If, for example, you wanted to perform load balancing with four mail delivery servers, you could set the priority to "10" for each of them. Or, if you had two mail delivery servers, but you wanted to use the second as a backup in case the first became overloaded, you could set the first server to "10" and the second to "40."
    7. Click Add.

      The server is added to the address list.

    8. Repeat steps 6,7, and 8 for each server that you want to add. To remove a server from this list, select the check box next to the address, and click Delete.

    9. When you have finished adding servers, click OK.

      The new server information is displayed in the Mail delivery servers table.
