That FAQ answer predates the advent of content filtering, so it is not
the current best way to do this.

Actually, they are defaults for legacy spam filters, but you want to
use content filtering, not header filtering.


To pass only plain text parts from essentially all messages set the
following in Content filtering->pass_mime_types:

multipart/mixed
multipart/alternative
message/rfc822
text/plain

If you also want to allow pgp signed messages, add:

multipart/signed
application/pgp-signature

Also, set filter content to Yes and set filter_action as desired. If
you want to try HTML to plain text conversion, you can set
convert_html_to_plaintext to Yes and add 'text/html' to
pass_mime_types.
