TITLE   :XFOR: Inbound Mail Failure Error with MS Mail and IMC
PRODUCT :Microsoft Exchange
PROD/VER:WinNT:4.0,5.0,5.5
OPER/SYS:
KEYWORDS:

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

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Microsoft Exchange Internet Mail Connector (IMC) administrator may receive
inbound mail failures when trying to deliver a message to a MS Mail custom
recipient.

   -or-

When you attempt to send a message to MS Mail users through an Exchange Internet
Mail Connector you may receive a non-delivery report (NDR) similar to the
following:

   Your message did not reach some or all of the intended recipients.

   The following recipient(s) could not be reached:

   user@company on 6/26/97 18:58:04 PM
   Recipient Not Found
   [MSEXCH:IMC:ROHR:EXGATE:ROHR_EX]

CAUSE
=====

This is not an Exchange Server problem. If the customer is using a UNIX "alias
file" to resolve the names, it is a third-party issue.

If the customer is not using an "alias file" then the problem is caused by an
incorrect SMTP address in Exchange Server.

RESOLUTION
==========

Confirm the MS Mail custom recipient SMTP address is the same as the address
given by the sender. If the address is different the customer may be using alias
files to redirect the message to an alternate address.

For example:

The SMTP address on the custom recipient is me@my.house.com
The SMTP address the message is to be addressed to is me@house.com

Messages to me@house.com are returned with a Non Delivery Receipt. Messages to
me@my.house.com are sent and received.

If the problem is affecting all users, then perform the following steps to change
the default site addressing:

1. In the Exchange Server Administrator program, click Organization, Site,
   Configuration Container, and then double-click on the Site Addressing.

2. Select the Site Addressing property page, highlight the SMTP address, and
   then click Edit.

3. Modify the address as needed.

If the problem is affecting one recipient, then modify the SMTP address of that
recipient as follows:

1. Select the container of the recipient in the left pane.

2. Double-click the recipient, and select E-mail Addresses.

3. Select the SMTP address, click Edit, then modify the address as needed.

NOTE: When you edit an existing partial e-mail address, you are given the
opportunity to update addressing information for all Microsoft Exchange
recipients with the new information.
