Description of updates for problems with forwarded messages in DMS-enabled Exchange Server 2003 organizations (889463)

SYMPTOMS

Consider this scenario:

Server A, Server B, and Server C are located in three different Exchange organizations.
Each organization is Defense Message System (DMS)-enabled.
Server A is connected to Server B by an X.400 connector.
Server B is connected to Server C by an X.400 connector.
An e-mail message is sent from an Exchange Server 2003 mailbox that is located on Server A to an invalid Exchange Server 2003 recipient that is located on Server B.
The message is forwarded to a valid alternative recipient that is located on Server C.

In this scenario, you may experience the following symptoms:

Exchange Server 2003 does not include the redirection history with the original recipient name on originator-requested alternative recipient (ORAR) rerouting that uses the Extension 25 property.
Address length padding is miscalculated when Exchange Server 2003 validates the PR_REDIRECTION_HISTORY property.
A non-delivery report (NDR) is received by the message originator on Server A.
