I am one of the editors of the dnswl.org database, and while it is tempting to participate in the mass-checks, considering the effects that would have on the dnswl tests or not, I think it's better to not have that skew. I like having the QA test results to independently evaluate dnswl.
I wonder if anybody else watches any of the QA results as closely as us dnswl folks: http://www.chaosreigns.com/dnswl/ And it still disturbs me that mass checks use anything but the test results at the time the email is originally scored (like from the "tests" value of the X-Spam-Status header). Since I'm sure the time variance improves the accuracy of things like razor and dnswl, and all the blacklists. -- "Blessed are the cracked, for they shall let in the light." http://www.ChaosReigns.com
