We just resolved this pretty well with Mark's help. Here are my notes for
how we fixed it. The full discussion took place in recent days, so if you
are just now joining the list, check this week's archives.

Supporting HTML email with correct footers:

Is text/html in the pass_mime_types content filtering setting?

Is collapse_alternatives set to No?

I suspect that one or both of those is not the case, and setting them
will solve your problem.

I further suspect that collapse_alternatives is the issue. Gmail
creates a multi-part alternative message with a text/plain alternative
containing Gmail's conversion of the HTML and a text/html alternative
containing the HTML.

If collapse_alternatives is Yes, Mailman simply replaces the
multipart/alternative part with the first (i.e.text/plain) alternative.

See the FAQ at <http://wiki.list.org/x/84A9> for a more
complete discussion.
