Yeah, but high power != high top end speed. Sometimes it's nice to be able to just accelerate from 0 to 60 fast. Pushed back in the seat, cigarettes flying off the dash into the back seat! Pretty hard to get hurt doing that, but it is a lot of fun to smell the burning rubber.
I agree...I think it works well as a partial answer. One problem that I don't think is addressed by any of the proposed answers is that many spammers get a new domain for $10, set up their RMX records for it, then blast out a few million emails, close it, discard the domain, and take a fresh one, repeating the process.
One could argue that a referral based service would prevent ongoing activities from the domain as it would be soon reported to the database and "blacklisted" for unscrupulous activities, but by then, the spam has already been sent.
Administrators could refuse email from senders without a positive listing in the global database, but this would prevent legitimate new domains from sending mail.
