Body=1 with no Fuz1 or Fuz2

I had a complaint from a user that obvious spam was getting through
to her.  It has an X-DCC header like this:

	X-DCC-UofM-Metrics: electra 1032; Body=1

When I checked the DCC log, it was a typical multipart/alternative
MIME message with a text/plain and a text/html portion.  Why would
there be no Fuz1 and Fuz2 checksums in this case?  Could they be
using funny MIME headers?  Here's how they look:

	Message-ID: <UtK6uXq4A5Yci58jSK72cg@greatfreestuffsite.com>
	Date: Sun, 21 Jan 2007 03:09:36 -0500 (EST)
	Mime-Version: 1.0
	Content-Type: multipart/alternative; boundary="=_UtK6uXq4A5Yci58jSK72cg"
	
	
	--=_UtK6uXq4A5Yci58jSK72cg
	Content-Type: text/plain; charset=us-ascii
	Content-Transfer-Encoding: 8bit
	Content-Disposition: inline
	...
	--=_UtK6uXq4A5Yci58jSK72cg
	Content-Type: text/html; charset=us-ascii;
	Content-Transfer-Encoding: 8bit
	Content-Disposition: inline
	...
	--=_UtK6uXq4A5Yci58jSK72cg--

Here are the checksums:

X-DCC-UofM-Metrics: electra 1032; Body=1
                            reported: 1               checksum  server

I can send the entire DCC log of this and similar messages, if that
will help.
