SYMPTOMS
Consider the following scenario:
 * Server A, Server B, and Server C are located in three different Microsoft Exchange Server 2003 organizations.
 * Server A is connected to Server B by an X400 connector.
 * Server B is connected to Server C by an X400 connector.

When 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 and the message is forwarded to a valid alternate recipient that is located on Server C, a non-delivery report (NDR) is received by the message originator on Server A. The NDR discusses a looping error from Server B.
