Okay, I've had a look at SPF.

It suffers the same problem as digital signing. It requires that all of your email correspondants use it in order for it to be effective.

As an email user, I don't have control over how my correspondants use email. The only thing I have control over is what email address I give them. By piggy-backing a username and password in the address I give each of my correspondants, I can identify and authenticate them - without buy in from them.

That is the essence of this Segmail spec - and what makes it different from DSPAM, SPF, Statistical Junk Mail Filters, Challenge/Response systems and Digital Signing.
