SUMMARY

This article explains how to set up the Microsoft Exchange Server Internet Mail Service to reroute SMTP message to different Exchange Organizations using the SMTP protocol.

MORE INFORMATION

Scenario

  • Two Exchange Organizations on the same segment:
    • Org1: Microsoft (domain: Microsoft.com) (Site:abc) (Server:123)
    • Org2: Microsoft-Europe (domain: Microsoft-Europe.com and Microsoft-Africa.com) (Site:def) (Server:456)
  • MX records for all domains are pointing to the Exchange Server (Microsoft)

Configuration

  1. On the Microsoft-Europe Organization, open the Internet Mail Service Properties page, and on the Routing tab, remove the Microsoft.com domain.
  2. Keep the Microsoft-Europe.com and Microsoft-Africa.com domains as inbound.
  3. Stop and re-start the Internet Mail Service.
  4. On the Microsoft Organization, open the Internet Mail Service Properties page, and on the Routing tab, remove all domains except Microsoft.com; keep Microsoft.com as inbound only.
  5. Go to the Connections tab, and under Message Delivery, click E-mail Domain. In the Forward all messages for this domain to host box, add the Microsoft-Europe.com and Microsoft-Africa.com domains, and enter the IP of the Microsoft-Europe mail server.
  6. Stop and re-start the Internet Mail Service.
  7. Make sure that either Domain Name System (DNS) is configured with correct host records, or use the Hosts file for proper hostname resolution.
