The information in this article applies to:

- Microsoft Exchange Server, version 5.0 
-------------------------------------------------------------------------------


SYMPTOMS
========

The Microsoft Exchange Server Internet Mail Service may fail to convert an
incoming internet mail message.

CAUSE
=====

This problem can be caused by the Internet Mail Service receiving messages with
wrapped mail message headers. When the Internet Mail Service unwraps these
headers it removes all spaces. Although this conforms to RFC, this creates a
message with an invalid message header and thus the message cannot be processed.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server,
version 5.0. This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 5.0. For information on obtaining the Service
Pack, query on the following word in the Microsoft Knowledge Base:

Additional query words: bounced message undeliverable mail
