new DK results

[Justin Mason <jm...@jmason.org>]

from a mass-check run I did last night.  these are more promising;
12% of ham whitelistable:

  19992     9999     9993    0.500   0.00    0.00  (all messages)
100.000  50.0150  49.9850    0.500   0.00    0.00  (all messages as %)
  6.338   0.0500  12.6288    0.004   1.00    0.00  DK_SIGNED
  0.005   0.0000   0.0100    0.000   0.53    0.00  DK_POLICY_SIGNALL
  0.485   0.0400   0.9307    0.041   0.47   -0.00  DK_VERIFIED
  4.627   5.5506   3.7026    0.600   0.06    0.00  DK_POLICY_TESTING
  5.162   6.1206   4.2029    0.593   0.00    0.00  DK_POLICY_SIGNSOME

this was achieved by adding code which strips off "known appended"
headers from the message, such as X-Spam-*, Status, IMAPBase etc.

Records that passed verification were:

    954 gmail.com
    270 yahoo.com
     10 crynwr.com
      9 earthlink.net
      6 space.net
      5 yahoo-inc.com
      5 omniti.com
      1 sendmail.com
      1 altn.com

and that's it.  AFAICS, most of those domains have only one selector,
so that's a puny 9 DNS lookups?  looking quite promising. ;)
