So what does this do? It enables an email server to immediately verify that an email message originated from an authenticated source; if not, it dumps the email immediately. Problem solved.

I don't see where this helps anything. You're creating a lot of new infrastructure that someone will have to pay for.

And you're ignoring the fact that lots of overseas ISPs exist solely for spammers... wannado.fr and hinet.net for examples... and they would be willing to pay the price to get into the "network". Then they'd have to be blacklisted -- just as they are now.

And on top of that, you've come up with a nice little way of tracking e-mail addresses and number of e-mails sent, which just might come in handy to the government someday.

Why? OSS devs aren't capable of producing this architecture?

It doesn't matter whether they "get into the network". All mail senders would have to pay for their specific volume of mail. So those that send more would pay more -- and it would naturally put a stop to this kind of abuse.

The government can already do that now (ie. Carnivore). So this doesn't introduce significantly better capability for law enforcement -- other than better traceability.
