DOCUMENT:Q169683 21-APR-1999 [exchange] TITLE :XFOR: New IMS Routing Functionality in Exchange Server 5.0 SP2 PRODUCT :Microsoft Exchange PROD/VER:WinNT:5.0 OPER/SYS: KEYWORDS:kbusage ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.0 ------------------------------------------------------------------------------- SUMMARY ======= In Microsoft Exchange Server version 5.0, the Internet Mail Service has the added ability to reroute Internet mail. To configure this feature, you have to specify any domain(s) that will be handled by Exchange Server. When you specify a domain in the Routing tab of the Internet Mail Service, a subdomain match is implied. In Exchange Server 5.0 Service Pack 2 (SP2), you now have the ability to specify an exact domain match in the routing list. MORE INFORMATION ================ In Exchange Server 5.0 and Exchange Server 5.0 Service Pack 1 (SP1), if you specify ms.com host1.ms.com in the routing list, then this implies that you also want other subdomains (for example, sales.ms.com) to be rerouted to host1.ms.com. The rerouting capabilities have been modified in Exchange Server 5.0 SP2 to allow you to specify an exact domain match instead of always doing subdomain matches. To do this you must add a pound sign (#) in front of any domains you want exact matches for. A domain with a pound sign prefix indicates that domain must exactly match the destination domain (the domain in user@domain) to trigger the associated routing action. For example, take the following list: Sent To Route To ======= ======== ms.com host1.ms.com #ms.com x.ms.com Mail should be routed as follows: User@ms.com ===> routed inbound User@sales.ms.com ===> routed to host1.ms.com User@x.ms.com ===> routed inbound User@pms.com ===> routed to pms.com User@abc.x.ms.com ===> routed inbound The matches are done in the following order: 1. Check for a match in the exact match list. 2. Check for best match among the non-exact match list. 3. If no match, reroute to the destination domain. This feature is included in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0.
