Yusuf and Suresh of Outblaze have provided a different version of the Outblaze data which excludes some sender domains which are not really relevant to SURBL use. I've put the revised list up as:
ob2.surbl.org
Please beta test it against ob.surbl.org
Please also test ab.surbl.org which are the top 425 or so spamvertised sites from abusebutler.com.
So please beta test:
ob.surbl.org ob2.surbl.org ab.surbl.org
and let us know the results here. ob2 and ab are only on my name server right now, so please don't test on any really large volume mail servers. Hand-checked corpus testing would be ideal, and we're particularly interested in false positives and spam detection percentages.
Thanks,
Jeff C.
