Viktor Dukhovni says that anything like DKIM/SPF is bound to fail.

One problem is confusables: users can't really distinguish them, and
some can be counted on just doing whatever it takes to give their money
to the phisher, no matter what.  In other words, the problem with e-mail
is that strangers can start conversations with you.  (Whereas with web
services you start the conversations with them, which is not as big a
problem.)
