There are no HTML parts left after filtering because text/html is not
in pass_mime_types.

>What does the second part mean? How do you configure your site to allow these conversions? Is it something a regular administrator could do, or is it something that the host site of my Mailman list has to do?

It means the HTML to plain text conversion is done by a command set by
the Mailman site administrator. The default command is

HTML_TO_PLAIN_TEXT_COMMAND = '/usr/bin/lynx -dump %(filename)s'

which may not work on all systems.
