Not exactly the most obvious naming scheme. :-)
There is no limit to the number of small bins we could sort these scores
into. On my system, I could specify the authentication methods and
results,
The smaller the bin, the less effective the reputation system. The
above list was fine tuned over 6 months to make the bins as big as
possible, while avoiding "unfair" comparisons (like aol.com:SPF
to aol.com:neutral) to minimize false rejections.
I specifically do *not* want to see all combinations of possible
authentication scopes, methods, and results. I am looking
for a validated ID. I'll take several kinds, but I need one to track
your reputation.
It would be reasonable to choose a qualifier naming scheme for the chosen
IDs that I accept that reflects your concern, if you think it would
make the system more attractive. Something like this?
Old nam New name
SPF | (mfrom) | SPF | (Pass) | MF/SP/PAS
GUESS | (mfrom) | SPF-guess | (Pass) | MF/GU/PAS
HELO | helo | (SPF/SPF-guess) | (Pass) | HE/SP+GU/PAS
neutral | (mfrom) | (SPF) | Neutral | MF/SP/NEU
softfail | (mfrom) | (SPF) | SoftFail| MF/SP/SOF
IP | ip-addr | (valid rDNS) | (match) | IP/RD/VAL
Rather cumbersome. I think the table belongs in the documentation,
not encoded in the qualifier. (Thanks for the table.)
