Before we plunge off on this tangent again, is there anyone out there
writing an SPF parser that would make any use of this "added information"?
Currently even if my SPF filtered all mail where the SPF result is 'fail',
'softfail' or 'neutral' and even if it used fallbacks for yahoo.com etc.,
only about 0.5% of the mail would be catched by SPF but not by other
filters. So currently for my server the performance of SPF is insignificant.
In the next time it may be increased by a factor of 10 to 5%, but still that
is insignificant. Therefore I will not add probabilities as suggested by
Shelby to my SPF implementation.
