I would err on the side of letting mail through.  Also, if you reject mail,
you might initially want to use "quarantine_entire_message" so if some
irate client needs the mail, you can at least retrieve it from the spool.

I do not recommend indiscriminately banning HTML mail.  I think it's
better to use a tool like SpamAssassin to do a more sophisticated
analysis of the mail.

For what it's worth, I host two (main) domains on my mail server
(roaringpenguin.com and artandframingsolutions.com).  Appended are my
rules about HTML.  As you can see, I accept HTML mail from certain
domains and some particular mailing lists, and then some general
patterns for mailing lists.  I also accept HTML if either of my
domains appears in the "To:" or "Cc:" list.  I still get a fair bit of
rejected HTML mail --- all of it spam, as far as I can tell.

Regards,

David.
