For example, 212.227.126.135, scores 4 out of a 100 on senderscore. It also currently hits just sorbs. The individual score for each would have to be so low, even with such a poor reputation, that it hardly makes it worthwhile. I can't reject just on the almost worst reputation as you can have or just on sorbs, and the combination of the two isn't significant enough either.
and hence you score several DNSBL *and* DNSWL and make decisions on the final score
I also meant to point out that with a reputation like 4 out of a 100, you'd think it would be listed on more RBLs than just sorbs. Something is wrong there. A mail server doesn't receive an absolutely horrible reputation without being blacklisted elsewhere.
bla - it takes time until a IP makes it to different RBL's and hence use many of them with moderate scoring so that you can make useful decisions and liekly have new offenders on enugh most of the time
Senderscore is not trustworthy
NO RBL alone is trustworthy, hence you score them in the MTA as well as in the contentfilter
