How can I restrict distribution lists for internal use only?

Distribution list (DL) security: We have configured a few groups (DLs) in Exchange 2000 server. We would like to restrict these DLs to internal use, and external users should not be able to send mails to these DLs. Is there any way to configure this in Exchange 2000? Yes, but the configuration is actually done using Active Directory Users and Computers (ADUC). Open up the distribution list properties using ADUC on a machine that also has Exchange System Manager installed (so that the Exchange extensions to ADUC are added). Then go to the Message Restrictions area on the Exchange General tab and specify who can send messages to the list.
