I have been thinking about the "whitelist" principle for a while,
but I don't believe it can work now, because what would happen
when one person with a whitelist wants to mail to another
person with a whitelist ?  The first person must add the
second person in his whitelist.  Although this is possible,
I don't think you can expect this from 'normal' users: they
will forget it.  It would be possible if your whitelist could
be updated automatically when you send mail, but I do not think
there is any mail reader around which can do this at this moment.
With mailing lists it would be even more complex, since your
first mail goes to majordomo or listserv, and you receive mail from
the list address.
A similar solution would be that everyone uses digitally signed
E-mail, and that you refuse unsigned mail (and mail from bad CA's).

Does anybody know there are any initiatives in one of these
directions ?
