The question is not making the change, rather justifying it. You need to
show how this system will reduce spam and by how much, in order to
justify change to the entire Internet email architecture.
Confused! how is this a "change to the entire Internet email architecture."
It is a modification or even a "grafting"

1. SPAM AND CONSENT
...
its definition varies from
"unsolicited commercial email" to "any email the
recipient does not want". Often there are no technical
differences between spam and "acceptable" email.
...
by this definition spam has no definition
so its about choice, the recipients choice because it is he who ultimately
decides what is spam for him(her)
Therefore by empowering the recipient to control from whom he receives
e-mail then in fact we obliterate it from the face of the earth.
because what is left is acceptable to the recipient.
the very first and most powerful application is the ability to deny mail
from forged sources
this is without a shadow of a doubt the source of most "objectionable"
e-mail
and this is achieved automatically the source MUST identify itself or it
won't get the call back

P.S.
I am surprised no one has raised one particular flaw
that is ISP's who host scripts that are open to abuse e.g. some versions of
formmail
I am mentioning it now so people don't go "ah ha you missed that one didn't
you"
by virtue of the fact that the ISP get's an automatic reject message. ISP's
should pick this up early and correct the problem
