    2. Under Action, click [Disable] for the domain that you want local delivery disabled.

    3. When prompted, click Disableto confirm.
      • If you are only disabling email for your domain, stop here.
      • If you need to configure email to point to a remote mail server, continue to Step 4.

    4. Under the MX Records section, click [Edit].

    5. Enter the appropriate settings for your remote mail server and click Save.

      • Preference Number: An integer, ranging from 0-65535, indicating the order in which records should be attempted. Lower numbers will be processed before higher numbers.
      • Mail Server: The name of the destination server where mail traffic will be directed.
