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

  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.

  check box.
