I was violently in agreement with that assessment even _without_ the
patent issues, which I personally am more than happy to ignore (at my
peril, as you say).

When considered holistically, the domain/IP verification schemes don't
actually manage to achieve anything more than CSV does -- they only give
a way to determine how much to trust the individual mail server which is
offering the mail.

Thus, the heartburn of requiring ubiquitous deployment of SRS and the
addition of the Forwarded-For: header was too much for me, even without
the patent. There are better answers.
