It seems to me that the default score of from 1.2 to 1.9, for messages originating from URIs which are Black listed in any of the various JP, AB, OB, PH, SC, ... lists, should be significantly higher, perhaps nearly the default required score of 5.0
Some information is at http://ruleqa.spamassassin.org, including the fact that 86% of URIBL_JP_SURBL hits also hit URIBL_OB_SURBL 66% of URIBL_JP_SURBL hits also hit URIBL_WS_SURBL 56% of URIBL_JP_SURBL hits also hit URIBL_AB_SURBL etc Is there a discussion of the tests and scores and philosophy including but not limited to these somewhere?
