Subject: RE: [spf-discuss] Maybe simple question
Don't forget that Edward is the author of eMVP. From his site:
Yes, that's true.
I have shown that spf cannot succeed even theoretically, but nobody seems to
understand what I said, or is unwilling to think about it.
Given that compatibility with smtp must be maintained, then
There are two types of authentication scheme that can work, and spf is
neither of them.
spf has some characteristics in common with successful authentication
mechanisms, but it does not comply adequately.
Granted, spf is better than nothing, because it will stop spammers from
forging hotmail or yahoo. But as I described in my email 1 minute ago, it
will not stop spam. They can always easily and quickly forge somebody.
BTW, for those of you who read the emvp site:
emvp is well thought out, but poorly documented. All of the work so far has
been mostly offsite and verbal, not much written.
