[Mark Shewmaker]
(One evolutionary step: Instead of the middle-value being "new",
make it a plain "unknown", with all domains with no info in the
system having "unknown" reputations. Another step from there would
be for the RHS system to return an answer from "0" to "100", with
the "unknown" settable by the end user but by default being between
10 and 90.)
Why 0-100 ? 127.0.0.2-127.255.255.255 - 16581373 possible values while at
most 10000 will be valuable.
We can possibly create something like this:
spfv1 IN TXT "v=spf1 -exists:%{l}.bl.spamcop.net>1250 ~all"
