Procedure

1. Navigate to Policy → Internal Addresses.
   The Internal Addresses screen appears.
2. Under Internal Domains and User Groups, select one of the following from the drop-down box:
   • Enter domain: Specify a domain and click >>. Do not type the "@" or user name parts of an email address. For example, domainname or domainname1.domainname2 are valid; user@domainname is invalid.

     Note 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.

   • Search for LDAP group: A screen for searching the LDAP groups appears. Specify an LDAP group name (not an individual LDAP user) that you want to search in the text box and click Search. The search result appears in the list box. To add it to the Selected list, click the LDAP group and then click >>.

     Note When searching an LDAP group for the internal addresses, you can use wildcards at 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.

3. To import domains from a file, click Import from File and select the file.

   Tip Import both the exact domain and all sub-domains for best results.

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

   • domain.com: Imports the exact domain
   • *.domain.com: Imports all sub-domains
   • domain.org: Imports the exact domain

   Note The import file must be a text file containing one domain per line. You can use wildcards when specifying the domain.

4. Click Save.
