What you want to send and have Mailman pass is a multipart/alternative
message with a text/plain part and a text/html part.

To set Mailman's content filtering to accept and deliver this, you need
at least

text/plain part

in pass_mime_types, and you need to set collapse_alternatives to No and
convert_html_to_plaintext to No.

This depends on your MUA. You appear to be using "Microsoft Office
Outlook 11". I really have no idea how to configure MS Outlook, but as
a guess, there is certainly some setting to compose a message as HTML,
and it is likely that if you compose an HTML message, it will be sent
as multipart/alternative.
