XFOR: Non-Delivery Report Returned for SMTP Recipient Through the Exchange Notes Connector

ID: Q242287

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

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

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.
