SUMMARY

This article describes how to prevent outbound Simple Mail Transfer Protocol
(SMTP) messages from going to particular domains.

MORE INFORMATION
================

1. Install an independent server that is running Exchange Server 5.5 and create
   an inbound-only Internet Mail Service. Do not join the existing Exchange
   organization.

2. Double-click the Internet Mail Service object, click the Routing tab, and
   then click the "Reroute incoming SMTP mail" check box. (This option is
   required for POP3/IMAP4 support.)

3. Enter the domains that you do not want messages to go to, and then click to
   select the "Should be accepted as inbound" check box.

4. Click the Connections tab, click Message Filtering, and then type your domain
   in the "Prevent these domains and users" box. (Use the domain name in your
   users' SMTP addresses.) The format should be <xxxx>@<domain>.com.

5. Click to select the "Delete messages instead of moving to the Turf directory"
   check box.

   Mail Service.
