Adding a user directory-based route

Use the following steps to add a user directory-based delivery route on the page Settings > Inbound/Outbound > Mail Routing:

Steps

  1. Click Add.
    The Add User Directory-based Route page displays.
  2. In the field Name, enter a name for your new route. Length must be between 4 and 50 characters.
  3. From the pull-down menu Route order, select an order number to determine the scanning order of the route.
  4. From the pre-defined domains in the pull-down menu Domain group, select a destination domain.

    The default is Protected Domain. Information about the domain group appears in the Domain details box.

    To edit your selected domain group, click Edit to open the Edit Domain Group page. See Editing a domain group.

  5. In the section User Directories, select the user directories to use to define your route.

    Select from the list of currently defined user directories and click the arrow button to move them to the Selected User Directories box.

    ESMTP user directories are not included in the directory list. ESMTP user directories cannot be used for user directory-based routes.

    • To add a new user directory, click Add user directory.

      The Add User Directory page displays. See Adding and configuring a user directory.

    • To remove a user directory from the Recipients list, select it and click Delete.
  6. In the section Delivery Method, select the delivery method:
    • Based on the recipient’s domain (using the Domain Name System [DNS]).
    • Based on SMTP server IP address designation (using smart host). If you select this option, an SMTP Server List opens:
      1. Click Add to open the Add SMTP Server dialog box
      2. Enter the SMTP server IP address or hostname and port
      3. Mark the check box Enable MX lookup to enable the MX lookup function
        Important:

        If you entered an IP address in the previous step, the MX lookup option is not available.

        If you entered a hostname in the previous step, this option is available.

        • Mark the Enable MX lookup check box for message delivery based on the hostname MX record.
        • If you do not mark this check box, message delivery is based on the hostname A record.
      4. Enter a preference number for this server, from 1–65535. The default value is 5.

        If a single route has multiple defined server addresses, mail is delivered in order of server preference. When multiple routes have the same preference, round robin delivery is used.

        You may enter no more than 16 addresses in the SMTP Server List.

  7. In the section Delivery Options, select any desired security delivery options.
    1. Ensure email traffic uses opportunistic TLS protocols; mark the check box Use opportunistic Transport Layer Security (TLS).
    2. Ensure that users supply credentials; mark the check box Require authentication

      Enter the appropriate user name and password in the Authentication Information box. You must use the SMTP server IP address delivery method for users to authenticate.

  8. Click OK.
    The settings are saved and the new route displays under User Directory-based Routes.
