[Mailman-Users] Blocking multi-part messages with HTML

[Brian J. Watson]

For the lists that I manage on SourceForge, I would like to block all
emails with 'content-type: text/html'. This would significantly reduce
the amount of spam that appear on my lists. I've added that expression
to the bounce_matching_header (privacy) option, and it seems to block
message that contain just HTML. For multi-part messages, however, it
doesn't seem to recognize that a message contains a text/html part, and
merrily lets it through.

Is there a way to block multi-part messages that have a text/html part?
The version of Mailman used by SourceForge is 2.0.5.

Thanks.
