My concern is the need for new MUA purchases.

Why can't the server-side check modify the message to display the results
in an MUA-compatible way similar to the way that SpamAssassin modifies
bodies and (optionally) headers today?

Could you please supply an example of the modifications you propose in such a
way that:

1) It is displayable in Outlook Express

2) The display could not have been forged by the sender

Thanks,

Chris
