Address length padding may be miscalculated when Exchange Server 2003 validates the PR_REDIRECTION

SYMPTOMS

Consider this scenario:

A Microsoft Exchange Server 2003 organization is Defense Message System (DMS)-enabled.
Server A, Server B, and Server C are located in three different Exchange organizations.
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 alternate recipient that is located on Server C.

In this scenario, address length padding is miscalculated when Exchange Server 2003 validates the PR_REDIRECTION_HISTORY property.
