The degree to which I have control over that MTA represents my certainty

my domain. This is the way I would imagine most people/small businesses
that have their own domains operate. The problem is that my ISP has a LOT
of customers.
SPF Pass==not a forgery is only true for organizations running their own
MTA.
If you are saying that SPF is only for people that run their own MTA, then
its adoption is going to be very limited.
If I were a cutomer of an ISP I would be asking the ISP about implementing
SPF. In my case I am the ISP and we host about 1400 domains, all of them
are being SPFized. It just makes more sense for ISPs to be a part of the
solution.
