Is the Message-ID: in his copy the same as in the list post?

I won't say it's not possible, but I doubt it. If so it would be in an
underlying Python library module.

It sounds as if this could be a 'format=flowed' issue. Please post one
of these raw messages as sent to mailman. Put the message in a file with
a .txt extension and attach it to your post. You can remove all the
headers with identifying info. I want to see all the MIME-Version:,
Content-Type: and Content-Transfer-Encoding: headers, the boundaries and
the sub-part headers and the part content.
