lists.samba.org uses the Korea blacklist <http://korea.services.net/>.
This is about as broad and ugly a solution as you can get.
Unfortunately, it works: we get hundreds of attempted spams from Korea
every day, and random audits show that effectively zero are bonafide
This is (very close to) a distributed theft-of-service attack, since
any spams that were passed through would be amplified to thousands of
list recipients, incurring traffic charges for us and inconveniencing
readers. (Indeed, many readers would be bounced off the lists because
of their mailservers refusing the spam.)
I think we are on a long slow decline of SMTP. It needs to either be
replaced or greatly altered at either political or technical levels.
People are trying out different approaches, none of which is perfect.
Some of these approaches are based on requiring people to provide an
accountable identity so that they can be held responsible for spam.
Requiring transactions to go through ISP SMTP servers ties down a
sender as belonging to that ISP, and therefore helps hold ISPs
responsible for their behaviour.
