Q242287: XFOR: NDR Returned for SMTP Recipient Through Notes Connector

Article: Q242287
Product(s): Microsoft Exchange
Version(s): winnt:5.5
Operating System(s): 
Keyword(s): exc55
Last Modified: 10-NOV-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

Certain Lotus Notes clients surround SMTP recipient names with angle brackets
(< and >) before the messages are sent to the Notes Mail Router.

When these recipient names are sent through the Exchange Notes Connector, a
non-delivery report (NDR) is generated by the Exchange Notes Connector to the
Notes originator.

CAUSE
=====

This behavior occurs because the Exchange Notes Connector interprets the angle
brackets as part of the recipient address, rather than interpreting them as
delimiters.

RESOLUTION
==========

This problem can be resolved by using a different Notes client.

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

Steps to Reproduce the Problem
------------------------------

1. Configure an Exchange Server computer with Internet Mail Service and a Notes
  Connector.

2. Using a Notes client that is known to do this, send a message to a user in
  the form:

  username@domainname.com@EXCHANGE

The NDR is generated for <username@domainname.com>@EXCHANGE.

Known clients that do exhibit this behavior: Notes 5.0a client
Known clients that do not exhibit this behavior are: Notes 5.0.1a client.
