What has this to do with the SPF system ?
The thread was discussing the proper relationship between a sender
authentication scheme (which SPF is) and sender reputation schemes.
My view was that SPF is correctly making as few assumptions as possible with
respect to the design of such a reputation scheme. This was challenged as
wrong in preference to integrating a one-size-fits-all reputation scheme into
the authentication system. Or at least that is the impression I got.
The supposedly 'offtopic' discussion (on my part at least) was an attempt to
explain the political difficulty of establishing common requirements for a
reputation scheme. Difficulties which would present a barrier to SPF's
adoption if any form of reputation scheme was 'welded into it'.

SPF is not a long-term solution to reduce spam unless operated in conjuction
with an effective reputation scheme. Reputation is such an ambiguous human
concept that a design which does not consider human motivation is likely to
be ill-informed.
