Here's the stats for a recent run of mine using the at-time-of-receipt
network test results:

OVERALL    SPAM%     HAM%     S/O    RANK   SCORE  NAME
      0   946808    55766    0.944   0.00    0.00  (all messages)
0.00000  94.4377   5.5623    0.944   0.00    0.00  (all messages as %)
 60.480  64.0420   0.0018    1.000   1.00    0.00  URIBL_JP_SURBL

 43.095  45.6271   0.1022    0.998   0.91    0.00  URIBL_OB_SURBL
  0.712   0.7537   0.0072    0.991   0.83    0.00  URIBL_PH_SURBL

I don't know what the overlap and such is on these.

FWIW: It seems like everytime I report a SURBL FP it's because of OB.  So I'm
all for cleaning up the list/listing criteria.
