As I've mentioned before, I've been working on trying to get SPF checking
better packaged and integrated in Ubuntu, the Linux distibution I use.
I felt that there was a hole an the available options. There are a number of
Python policy daemons that do SPF (the ones I know of are linked on the
Implementations page - http://www.openspf.org/Implementations), but none of
them were just SPF. I decided to create a separate policy daemon for a
couple of reasons:
1. To make the simplest policy daemon possible to get a Python solution for
Postfix packaged for Ubuntu.
2. To enable me to extend a policy daemon to include additional SPF related
features (e.g. forwarder whitelisting) that other programs I've looked at
lacked and serve as a sample.
The source for my effort is Tumgreyspf
(http://www.tummy.com/Community/software/tumgreyspf/). I've used their code
for my own experimentation. If you are interested in SPF and greylisting,
then I recommend it.
There is a page for software that does not have a primary release point other
than openspf.org. The Python Postfix policy daemon for SPF is there as well
as a few other items (including Meng's Perl Postfix policy daemon for SPF
that I hope to update for Julian's new Mail::SPF library soon).

Although this is a new program, it derives from well tested code and I have
tested it myself. I'm interested in feedback both on the program and
documentation.
