Look. The specification, in effect, says
If you get a Received-SPF: neutral header, you MUST
pretend that SPF evaluation had not occurred at all.
A Bayesian filter chooses to ignore that "MUST".
Who is at fault, the SPF specification, or the Bayesian filters?\
This will be a self-correcting problem, anyway.
It's happening because right now, a high percentage of the people publishing
SPF are apparently spammers. (This isn't an uncommon problem. Remember that
company that copyrighted a haiku and started licensing it as a sort of bonded
sender program? Pretty much every message I've gotten with one of those in
the headers has been spam.)
As more people publish, and people start marking those messages as 'not spam'
in their filtering software, the weighting in the filters will change.
