http://spamassassin.apache.org/tests.html isn't being maintained, but was a useful quick reference for tests and their default scores. Is there any chance of it being revived, or is there a current equivalent?
As a consequence of that page being deprecated, http://wiki.apache.org/spamassassin/HowScoresAreAssigned and every wiki entry for a specific test contains this piece of misinformation: "The default scores for this rule can be found in the online list of tests." Someone should probably make a sweep of the wiki pages and remove that. I'd do it myself, but the pages have all been tagged as "immutable" since 2009.
