XFOR: Notes R5 Recipient Cannot Reply to SMTP Message Sent Through Internet Mail Service

ID: Q248383

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

When you send a Simple Mail Transfer Protocol (SMTP) message to a Lotus Notes recipient, and then the Notes recipient attempts to reply to the message, they may receive a non-delivery report (NDR), and the following event may appear in the event log:

Event ID: 31040
Source: MSExchangeNotes
Type: Warning
Description: No valid message recipients in message.

In addition, the Exchange Server connectivity administrator log may contain an entry similar to the following:

1998/04/06 13:20:34- LME-NOTES-MEXOUT(01ec) 2 31040:No valid message recipients in message >> mexout(2366)

This problem is known to occur when the message is sent to an Exchange Server computer through the Internet Mail Service, and then routed to a Notes Release 5 (R5) server through the Exchange Notes Connector. The problem only occurs if the recipient uses a Notes R5 client to reply to the message.

This problem may also occur when you attempt to send a new message from a Notes R5 client to an Exchange Server recipient. In this case, the problem is known to occur when you type the recipient's address in one of the following formats, and then send the message to a Notes R5 server through the Exchange Notes Connector:

User1@Host1@Domain1
User1@Host1@SMTP@Domain1
<User1@Host1>@Domain1

CAUSE

When the Notes recipient replies to the message using a Notes R5 client, Notes removes the display name from the transport Internet address encapsulated by Exchange Server and encloses the Internet address portion in angle brackets. The resulting address appears in a format similar to one of the following:

<User1@Host1>@SMTP@Domain1
<User1@Host1>@Domain1

The Exchange Notes Connector does not recognize explicitly encapsulated Internet addresses that contain angle brackets, but no display name, as in the first example above. In addition, the Exchange Notes Connector does not recognize implicitly encapsulated SMTP addresses that contain angle brackets, as in the second example above.

Note that the Notes R5 client only performs this conversion for transport addresses located in the Recipients property.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.
