TITLE   :XFOR: MSMI Won't Set SNADS as Reply-To Address
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:kbusage

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

 - Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you send mail to a Microsoft Mail user by means of the MS Mail Connector
Interchange (MSMI), the MSMI will not set the Custom Recipient's SNADS address
as the Reply To address. Instead, the MSMI uses a Microsoft- type address.

CAUSE
=====

Messages sent through the MSMI are always sent with a Microsoft-type Reply To
address, unless the sender does not have a Microsoft-type address, in which case
an X.400-type address will be set as the Reply To address.

RESOLUTION
==========

Apply the fix referenced below.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange version 4.0.

A supported fix is now available, but has not been fully regression-tested and
should be applied only to systems experiencing this specific problem. Unless you
are severely impacted by this specific problem, Microsoft recommends that you
wait for the next Service Pack that contains this fix. Contact Microsoft
Technical Support for more information.


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

A hotfix is now available from Microsoft that allows the MSMI to be set to send
the SNADS address as the Reply To address. With the hotfix installed, the
following registry value will be read:

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Services
MSExchangeMSMI
Parameters

Value Name: Send SNADS as Reply-To
Data Type: REG_DWORD

If this registry value is not present or is set to 0, the MSMI will always send
the Microsoft-type address as the Reply To if the sender has a Microsoft-type
defined.

If this registry value is present and set to 1, the MSMI will attempt to send the
message with a Reply To of SNADS if the sender has a SNADS address defined, if
not, it will revert back to the old behavior and send the message with the Reply
To set as Microsoft-type.

NOTE: Each Microsoft Mail postoffice receiving these messages will need to have
the SNADS access component installed in order to reply to these messages.
