of their rules, including all SURBL lists, against their ham and
spam corpora at their Rule QA site:
As you can see OB ranks significantly below the other SURBL
lists, with much higher FP rates around 0.1% compared to 0.01% to
0.025% or so. (Note that the Rule QA site seems to have occasional
glitches, so if the numbers seem out of range one week, check
Should we make that change?
