Looks like a nice addition to SPF and DKIM. Just one more little thing that we need to do - and we already have far too much to do. I agree with @incrediBILL, stop stupidity and you stop the spam. Monitize e-mail (getting bulk mail to the inbox) and you'd also stop the spam. Anyone know what the conversion rate on spam is these days. 1 in 200k?
