XCON: Non-Delivery Report States Recipient Not Recognized When a Large Message Is Sent (270910)

The information in this article applies to:

Microsoft Exchange Server 5.5 SP3

SYMPTOMS

After a user attempts to send an e-mail message over an X.400 Connector, the user may receive a non-delivery report (NDR) that contains the following text:
