Thanks so much for the tip Wayne. I'll complete my read of the latest
RFC before coding any further. Currently, I've ported the SPFJava
library/interface to a Windowz COM-ponent. This intended as a baseline
learning effort in support of the earlier drafts. I'll refactor it to be
RFC compliant, and upon completion of same, would be happy to offer it
up (with Neil Murray's blessing) if you think it's worthy.

Does anyone have a knee-jerk as to how compliant SPFJava is to the
current spec?

Thanks,

Monte

We are in the process of overhauling the website, and you are right,
this is not as well phrased as it should be.  We will try to clean it
up. 


That said, I would like to stress, however, that if you are creating a
new implementation of SPF, that you really need to reference the real
spec, RFC4408.  We put a *lot* of work into polishing the spec and
debating the correct phrasing of almost every sentence.

See:
http://www.ietf.org/rfc/rfc4408.txt
http://new.openspf.org/Specifications


The spec is intended to try and match the existing implementations, the
previous specs, and the critical items that we have learned about during
the deployment of SPF.  In the cases where these three goals conflict,
we tried hard to choose the safest and most compatible option.


Relying any other document, be it our website, other websites, older
specs, published books, etc., will likely give you worse results in
practice.
