mc-fast says thumbs up

Saturday, July 5th, 2008

Yay, mc-fast is back. And what a nice feedback it sent me…

Freqs for those rules in 'mc-fast' mass-check:
  MSECS    SPAM%     HAM%     S/O    RANK   SCORE  NAME
      0     1996     1999    0.500   0.00    0.00  (all messages)
0.00000  49.9625  50.0375    0.500   0.00    0.00  (all messages as %)
0.00000  41.1323   0.0000    1.000   1.00    0.01  T_PQRTW_4

Could it possibly be I just created a killer rule to identify > 40% spam with no false positives? Seriously low scoring spam. Using a single, really short RE? Could it possibly be there is one major spammer out there, that uses this easy to catch finger print on all his spam? And that no one spotted it before…?

Granted, that’s just a tiny pre-flight corpus used for some very basic, fast evaluation. Eagerly awaiting the real mass-check results tomorrow…
