So far so good. :-)  No false positives yet.  I think false negatives are
still more likely than false positives since this technique still uses SP
for the white list and SP is very forgiving.  Header only scoring is
slightly more prone to false positives than normal scoring but still very
biased against them.

Sooner or later a spam is bound to get through (nobody's perfect) but this
does raise the bar extremely high for the spammer.  I might wind up playing
with the choice of headers I use for scoring a little as time goes on.

All the best,
++Brian
