KEYWORDS:kb3rdparty kbother

======================================================================

The information in this article applies to:

SYMPTOMS
========

The Microsoft Exchange MS Mail Connector (Apple Talk) Message Transfer Agent
(MTA) will over utilize the CPU when processing a message with a subject that
contains 0xD. This will cause the Microsoft Exchange Server to become
unresponsive.

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

AT Mail does not allow users to have 0xD in the subject line but some gateways
to AT Mail do.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Microsoft Exchange Server 4.0 U.S.
Service Pack 2. For information on obtaining the service pack, query on the
