MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Virus-Checked: Checked X-Spam-Rating: minotaur-2.apache.org 1.6.2 0/1000/N Eric Kolve and I are looking at adjusting the default scores for SpamCopURI's SURBL lists, and we thought we might base them on the perceptron-weighted ones that SA3 is using. Can someone suggest how to read the output in the scores file? http://spamassassin.apache.org/full/3.0.x/dist/rules/50_scores.cf # The following block of scores were generated using the mass-checking # scripts, and a perceptron to determine the optimum scores which # resulted in minimum false positives or negatives. The scores are # weighted to produce roughly 1 false positive in 2500 non-spam messages # using the default threshold of 5.0. [...] score URIBL_AB_SURBL 0 2.007 0 0.417 score URIBL_OB_SURBL 0 1.996 0 3.213 score URIBL_PH_SURBL 0 0.839 0 2.000 score URIBL_SC_SURBL 0 3.897 0 4.263 score URIBL_WS_SURBL 0 0.539 0 1.462 So what do the columns above mean?
