To me, we know what the problem is - the SMTP specification! We
change it
and the problem is essentially solved!
From

The idea of replacing SMTP is appealing because it
permits thinking in terms of creating an infrastructure
that has accountability and restrictions built in.
Unfortunately an installed base the size of the
Internet is not likely to make such a change anytime
soon. It seems far more likely that successful spam
control mechanisms will be introduced as increments to
the existing Internet mail service.
Moreover, the feature of SMTP that is most responsible
for spam is the ability to receive mail from strangers.
Without this feature, there would be no flood of spam,
but many of the most valuable Internet commercial and
individual activities would also be impossible.
Replacing SMTP with a protocol that allows strangers to
send each other mail would not stop spam any more than
SMTP-AUTH stopped spam, contrary to insistent claims to
the contrary, before SMTP-AUTH became widely available
and used.
