Please beta test ds.surbl.org which is the 6dos data turned into a SURBL. In particular, please check the false positive rate and let us know what you find.
Please do not use ds.surbl.org for production mail servers as it is hosted only on my name server.
(Chris, the list has about 120,000 entries. Were there some .c files which we should exclude?)
Please note that I have removed ob2.surbl.org as it was for testing only and the data source for it is now used as ob.surbl.org.
