I run a mail server. I decide whose mail I accept. Who else should?

To be honest, I wouldn't try to block email from consumers at source. It
would be easy to do, so I think the ISPs must agree with me. If that
were to happen, the spammers won't give up and get proper jobs, they'll
put more effort into compromising networks which are still permitted to
send mail. Since spam from consumers is so much easier to identify, I
think we're better off as we are.

There is a big advantage in blocking spam at the SMTP level. The body
of the email never gets transmitted. So that 90-95% are spam sending
*attempts*, many of which are denied after only a few packets are
transferred. Allowing them to be sent and then identified and discarded
from peoples' mailboxes would add a great deal of Internet traffic, and
there will never be enough bandwidth...
