[Mailman-Users] how is content filtered in the presence of multipart/alternative?

[Skip Montanaro]

I read the FAQ and the content filtering page of the admin interface but
didn't see this answered.  Given these settings:

    filter_content:             Yes
    pass_mime_types:            multipart/mixed
                                multipart/alternative
                                text/plain
    convert_html_to_plaintext:  Yes

if a message is sent as multipart/alternative and it contains one text/plain
and one text/html section, is the text/html section deleted or just stripped
of HTML tags and retained as (a roughly duplicate) text/plain section?

Thx,
