Configuring Domain-Based Delivery

When InterScan™ Messaging Security Appliance (IMSA) receives an email message addressed to a certain domain, it passes the message to another SMTP server for delivery. If the SMTP server cannot resolve the IP address of the destination computer, IMSA needs access to a DNS server to resolve the IP address. Use this screen to specify a list of SMTP server domains and their corresponding SMTP servers.

Relay domain settings are different from Domain-based delivery settings. For an explanation, see About Domain-Based Delivery.

To configure domain-based delivery:

  1. Choose Administration > IMSA Configuration > SMTP Routing from the menu. The SMTP tab displays by default.

  2. Click Domain-based delivery.

  3. To change the display, do any of the following:

  4. To add a new domain and specify an associated SMTP server, click Add. The Destination Domain window appears.

  1. Next to Name, type the domain name.

  2. Next to Server address and Port, type the SMTP server FQDN or IP address and port number for the SMTP server to which you want IMSA to send email for this domain.

    Fully Qualified Domain Name

  3. Click OK.

  1. To delete an item from the list, select the check box next to the domain name and click Delete.

  2. Click Import from File to import delivery methods from a file. The following shows sample content of a delivery method text file:
