Hi,
Despite all the shortcomings of SPF, there may be one GOOD use:
Every once in a while I receive requests to whitelist certain sender email
addresses or domains - then I explain that we don't like to do that because
it would allow any spam that PRETENDS to come from that domain to pass.
Andy,
Since there is already an SPF Pass, Fail, and Neutral result, couldn't
you just create a rule that if the sender passes SPF that you apply a
large negative point value? Then you could apply that rule to only the
domains that you want to whitelist.

A true WHITELIST would mean that:
a) it could skip over all the other tests right from the start
b) it would work even if you have some tests that DELETE emails!
Your scheme would not prevent emails from being killed outright by Sniffer
or similar content tests.
