SYMPTOMS
========

Inside a multi-server site, a server may send multiple copies of a message to
the bridgehead server. This may occur in the case of a multi-recipient message
and a multi-connector bridgehead server: recipients being served by a different
connector.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:

STATUS
======

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

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

Only one copy of such a message should be relayed inside the site until the
message reaches the bridgehead server. It is then the bridgehead server's role
to make copies for the different connectors.
