SPF is an MTA level 'protocol' and thus the target audience is MTA authors.
You would get a better take up if you contacted all the MTA authors and
proposed they take part and implement SPF. Eventually all ISP's will replace
their software and if the MTA has SPF installed they are much more likely to
use it.
SPF is easily and efficiently implemented via MTA extension mechanisms.
For instance, as a sendmail milter. Postfix and Exim at a minimum and
even Exchange also have extension mechanisms capable of efficiently
implementing SPF. Having a pluggable module available for the MTA
counts as implementing it in my book - and is preferable to building
SPF into the MTA core. Because it makes it much easier to substitute
implementations or tweak policy.
