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     <inbound>
  x.ms.com    <inbound>

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. For information on obtaining the service pack, query on the
