a valid pointon the other if you post your ideas as well as get the ideas from others and people implement the combination of all the ideas
well at the end it makes spammers life harder and i still did not give up the idea that sooner or later spam dies because it may become no longer a business case
frankly i *every* MX out there would implement Postscreen or something else let any new IP wait 10 seconds before answer with REJECT for whatever reason and even if the cient is on the 7-days-whitelist for this test wait 2 seconds before try to receive data i doubt that it would be a business case
simple mathematics how much mail you in theory can deliver in a timeframe while completly ignore filters at that calculation
that combind with every ISP close outgoing port 25 for endusers and force them to use 587 with smtp-out as well as start every endusers PTR with "dynamic-" until one said "i run a mailserver here and need 25 opened as well as PTR xyz" and spam would be dead from one day to the next leaving only hacked real accounts which can be fixed with abuse mails and blacklist straight away everybody bouncing on postmaster/abuse
there are enough weapons to let spam die completly if every mailadmin and every tech people on ISP sides takes 30 minutes for brainstorming how to solve the problem and starts to act
