text/plain and text/html parts of a multipart/alternative message. There
are several ways to deal with this.

1)If you have a good, MIME aware MUA, set your digest type to MIME.

2)Train list posters to post only plain text (generally not possible,
but see <http://www.expita.com/nomime.html>).

3) Set the list's filter_content to Yes and either put things like


and not


in pass_mime_types, or if you want to accept HTML only messages, set
collapse_alternatives to Yes.
