Largely the point is it's unilateral so you don't _have_ to have an
agreed syntax. I've had an implementation purely in Exim configuration
since February -- http://david.woodhou.se/eximconf/include/routers-ses

Currently that stops the backscatter, and it stops fakes being delivered
to anyone who actually does SMTP sender verification callouts. It's been
suggested that we could implement a stunt DNS server and publish an SPF
record using 'exists' to get potential recipients to verify the
localpart that way, but I haven't bothered yet.
