The net effect of the above is to remove all attachments with filename
extensions equal to one of the extensions in the list.

This could affect your issue. You could try setting it to No. When it
is set to yes, Mailman will replace a multipart/alternative part with
text/plain and text/html sub parts with just the text/plain part. If
that happens to be 'blank' you will get the result below.
However, the original message you posted at
was not structured in this way. It was a simple text/html message.

I'm surprised because 'Yes' combined with other problems seems to me to
be the most likely cause of this.

That will allow everything to pass through Mailman as sent. Whether or
not this is a good idea depends on whether you want to filter the
attachments with matching file name extensions.
I would try setting collapse multipart/alternative to No first.

So it was manipulated by content filtering.

And content filtering converted it to a single text/plain part either
by collapsing a multipart/alternative part to the first subpart or by
converting an html part to plain text.
We think the second thing didn't happen because
convert_html_to_plaintext is No. The first thing is not consistent
with the message you posted earlier, so only further testing will tell.
Test 1 - set collapse multipart/alternative to No and see what happens.
If the post is still blank,
Test 2 - set filter_content.to No.
