Well, there isn't one.[1]  Take the case in point.  Your solution is also
a hack in that it depends on having an explicit whitelist.

Of course it's an excellent hack!  It works in a *lot* of cases of
interest to MLM admins, but in principle you don't want to keep
whitelists (well, my Mom can spam me :-) or blacklists.  It's content
that you want to filter on (or out).

[1]  Well, you could have a "bonded mail" solution: every message
arrives with a PayPal credit, and the reader either waives it or the
sender pays.  My sister gets a permanent waiver, the taxman and the
"performance enhancement" salesmen can pay up. ;-)  Problem is, that's
too easy to corrupt into a Goodmail solution where the ISP collects
the gelt.  There's also Hashcash, but that's not a terribly happy
solution for mailing lists.
