sc2.surbl.org, the improved version of the SpamCop SURBL list, is ready for testing. So is the new version of xs.surbl.org, which is now more accurate, has far fewer FPs, etc.
sc2 adds resolved IP checks, meaning sites hosted on the same networks are detected immediately upon the first report. It also means that folks should continue to use SpamCop reporting if they want to contribute to a very powerful SURBL list. Your SpamCop reports now have even more power in sc2. In cases of the worst spammers, SpamCop reporting leads to essentially immediate listing in sc2.
sc2 is on about 15 public nameservers and xs is on 22. That's probably not enough for running large production servers on, but it should be plenty for corpus checks and mail servers with small to medium message volumes.
If you have rsync access to the SURBL zone files you can also mirror the files locally for testing of course. The sc2 and xs zones are currently available via rsync. (If you have a large volume mail server, please apply for rsync access so that you can mirror the zone files locally: http://www3.surbl.org/rsync-signup.html and offload the public nameservers.)
After sc2 is tested for a while we will turn it into the production sc.surbl.org list, assuming it has better performance than the current list, which seems quite likely. At that point sc2 will go away, since it will have become sc.
xs may go into the 128th bit of multi.surbl.org if it tests well.
Please test sc2 and the revised xs and let us know how they perform for you. Those with large spam and ham corpora (such as the SpamAssassin developers) are encouraged to test and please let us know.
Here are SpamAssassin 3.0.1 and later configs for using these two lists:
urirhsbl URIBL_SC2_SURBL sc2.surbl.org. body URIBL_SC2_SURBL eval:check_uridnsbl('URIBL_SC2_SURBL') describe URIBL_SC2_SURBL Has URI in SC2 at http://www.surbl.org/lists.html tflags URIBL_SC2_SURBL net
score URIBL_SC2_SURBL 3.0
urirhsbl URIBL_XS_SURBL xs.surbl.org. body URIBL_XS_SURBL eval:check_uridnsbl('URIBL_XS_SURBL') describe URIBL_XS_SURBL Has URI in XS - Testing tflags URIBL_XS_SURBL net
score URIBL_XS_SURBL 2.0
SpamAssassin 2.64 rules and scores using SpamCopURI 0.22 or later look like this:
uri SC2_URI_RBL eval:check_spamcop_uri_rbl('sc2.surbl.org','127.0.0.2') describe SC2_URI_RBL Has URI in SC2 at http://www.surbl.org/lists.html tflags SC2_URI_RBL net
score SC2_URI_RBL 3.0
uri XS_URI_RBL eval:check_spamcop_uri_rbl('xs.surbl.org','127.0.0.2') describe XS_URI_RBL Has URI in XS - Testing tflags XS_URI_RBL net
score XS_URI_RBL 2.0
