Because the protocol's implementation is not the appropriate place to
deal with spammer, and this is one of the major driving forces that has
pushed internet email to the point of breakage.
A couple of things have been achieved. Nowadays spammers tend to register
their own domain in order to send spam which passes SPF/ DKIM/ DMARC. The net
effect is not so brilliant, but it tends to define the problem better. It's
not the wrong path; it's slow.
The protocol should be open to read, but under strict change control.
Implementation of the protocol should be open to anyone.
I believe those points are held. Note, BTW, that John Klensin, who is
authoring the SMTP standard, runs his own mail server and doesn't implement any
of SPF, DKIM or DMARC. The standard is being discussed and adjusted openly and
transparently. The only undesirable feature of this process, IMHO, is that it
takes years.
Bad actors should be kept out not by preventing them to implement the
protocol, but by preventing them from joining the network. The network must
be open only to actors that adhere strictly to the rules. This includes
operators AND end-users.
Yes, that's an easily stated naive principle. Unfortunately, there is no
globally accepted rule to tell bad actors from ordinary humans. Yet, the
Internet is /the/ occasion to work it out.
