One idea would be to have incoming mail processed so any HTML part is dropped and the plain text version used instead. I am sure I have seen some other mailing list do this. Interestingly some SPAM senders use mail with text and HTML parts where the mime headers indicate the two parts are alternatives whereas in fact the text is reasonable text designed not to alert a filter and the HTML is the real advert.
Recent versions of Mailman can drop the HTML part and use only the plain text version. I don't remember whether the one on lists.alug can. The admins could look to see if we can switch the old html moderation-hold filter into an automatic conversion...
Sadly, an increasing number of newsletter sending systems use mime headers to indicate the two parts are alternatives whereas the plain text part just includes some "click here for a web page that we can track" rubbish. Buyer beware!
