Defining Internal Users and Domains

Internal addresses refer to all the users on your network. InterScan™ Messaging Security Appliance (IMSA) references the internal address list when it analyzes a rule's route—a specific "To" and "From" combination that includes a recipient and sender address or domain, LDAP groups, or address groups.

Any senders and recipients in a rule's route must be on the Internal Addresses list if you selected incoming messages, outgoing messages or both incoming and outgoing messages when adding a new rule or modifying an existing rule.

If you are configuring an outgoing message, the Internal Address list applies to the senders. If you are configuring an incoming message, the Internal Address list applies to the recipients.

See Configuring the Route for more information.

 

To define internal users and domains:

  1. Choose Policy > Internal Addresses from the menu. The Internal Addresses screen appears.

  2. Under Internal Domains and User Groups, choose one of the following from the drop-down box:

You can use wildcards for domain names. For example, use *.domain.com to include all sub-domains for "domain.com". However, you cannot use two asterisks in the user name or domain name portion of the address or use the "@" symbol. *.*@domain.com and user@*.* are both invalid.
 

 

When selecting an LDAP group for the internal addresses, you can use wildcards in the beginning and/or at the end of the LDAP group if you have specified Microsoft Active Directory or Sun iPlanet Directory as the LDAP server. For example, A*, *A, *A* are all allowed. If you have selected Domino as the LDAP server, you can only use wildcards at the end.  For example, *A, *A* are not allowed.

 

  1. To import user groups from a file, click Import from File and select the file.

The following shows sample content of a domain list text file:

domain.com

*.domain.com

domain.org

 

The import file must be a text file containing one email address or group per line. You can use wildcards when specifying the email address or group.

 

  1. Click Save to save the new domain or LDAP group that appears on the Selected list.

If you are using the Configuration Wizard, click Next.
