This indicates the list header and footer are being added as separate
mime parts.

Or sending a single part, plain text only post in the character set of
the list language (us-ascii for English).

I think you're misinterpreting that post. I think she is saying her
problem was caused by a footer which consisted of only a blank line
and when she removed the footer completely, the problem went away.

The blank line is not the issue. If both a header and a footer are
added, either both will be added inline if possible, or both will be
added as separate MIME parts.

That should be part of the solution. The other part (at least in
Mailman 2.1.6 and above), is an attempt is made to convert everything
to unicode and then back to the character set of the list (us-ascii
for English). If this fails, an attempt is made to convert back to the
character set of the original post, and if that fails, the header and
footer are added as separate parts.

So the bottom line is the original post must be a single part, plain
text message, and in a declared character set that contains all the
characters used in the message, header and footer.

If you have set the poster's Outlook to send 'plain text only' to the
list, I suspect the problem may be "smart quotes" or other characters
in the message.
