SUMMARY
=======

When you attempt send a message to a Microsoft Exchange Distribution List (DL),
you might receive the following error:

  Unable to deliver the message due to a recipient problem.

This error will occur if you do not have an X.400 address. To add an X.400
address, the Microsoft Exchange administrator will need to follow these steps:

1. Start the Microsoft Exchange Administrator program.

2. Select the sender's mailbox.

3. Open the File menu, click Properties, click E-mail Addresses, click New,
  click X.400 Address, and add the X.400 address.

MORE INFORMATION
================

Mail can be sent to other users without any problem if an X.400 address is not
present. However, when mail is sent to a DL, the Microsoft Exchange Message
Transfer Agent (MTA) requires that the sender have an X.400 address.
