SYMPTOMS
Consider this scenario:
 * Server A, Server B, and Server C are located in three different Microsoft Exchange Server 2003 organizations.
 * Each organization is Defense Message System (DMS)-enabled.
 * Server A is connected to Server B by an X400 connector.
 * Server B is connected to Server C by an X400 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, a non-delivery report (NDR) is received by the message originator on Server A.

Additionally, 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.



CAUSE
This problem occurs because the X.500 distinguished name is removed from the ORAR in Exchange Server 2003.
