Thanks Hal,
Someone on LIST-OWNERS pointed out that the header contained (as yours
does):

} Content-Type: multipart/alternative;
} boundary="0-306616803-1187377333=:35642"
} Content-Transfer-Encoding: 8bit

Where a sucessful yahoo poster had:

> Content-Type:         text/plain; charset=iso-8859-1

Which may be the key to the problem.  I have asked the user to see if he
can set his yahoo mailer to plain text.  Does anyone know how so I can
pass it on?
