Another list to test: ab.surbl.org
by Jeff Chan 23 Jun '04

23 Jun '04

We have turned the top 425 or so domains from Andy Warner's AbuseButler - Spamvertised Sites list: http://spamvertised.abusebutler.com/ into a beta SURBL for testing: ab.surbl.org again this one is only hosted on a few name servers now so please don't use it for production yet. We'd like your feedback about performance, false positives, etc. Andy's data is quite similar in principle to my SpamCop data in sc.surbl.org. His list is ranked by number of batched reports in a 7 day window, and he has various data sources. I'm inviting Andy to discuss this further here. Jeff C.

I've tried like 5-6 mirrors to pick up the 2.63 Plug-In, and none of them can read the file. Is there someplace I can FTP the tarball from? Thanks!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Jeff Chan writes: >We are also looking into some other potential spam >URI data sources such as proxypots, etc.: > > http://proxypot.org/ Jeff -- a quick note on this; it has to be done very carefully. Many spammers are using "link poisoning" stuff like this: Get ov<A href="http://www.gimbel.org"></A>er 300 medicatlons online shlpp<A href="http://www.omniscient.com"></A>ed over<A href="http://www.proton.net"></A>nig<A href="http://www.cravet.org"></A>ht to your fr<A href="http://www.aristotelean.org"></A>ont do<A href="http://www.barnacle.com"></A>or with no pr<A href="http://www.lordosis.net"></A>escrlption. All of those are "www.{RANDOMWORD}.{com|net|org}". Eventually there's one real link, which *is* SURBL-listed. These are chaff. Now, SORBS for one seems to be listing some of these sites; presumably because they have a spamtrap-driven feed without enough human moderation. That's the danger here. (btw, there's arguments to be made that a better selection mechanism can "weed those out", but that needs to be careful too. - - Ignore .org/.net/.com? spammer will use .biz, .info, and ccTLDs. - - Ignore 0-length links (<a href=...></a>)? spammer will change to use <a href=...>{RANDOMWORD}</a>. - - Ignore "dictionary words" somehow? spammer will use random URLs from google, so "real" sites. so I don't think those approaches have much merit alone.) - --j. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Exmh CVS iD8DBQFA0JPeQTcbUG5Y7woRAnYYAJ9/fZaT3WLmU+gT8aAnT2rcduDo7QCg6BE1 dF1r9ciWtFpEdC4OBHdRSKE= =mnKX -----END PGP SIGNATURE-----

Local RBL list?
by Jeff Taylor 17 Jun '04

17 Jun '04

I haven't been able to find this covered anywhere, but I would like to use both the spamcop list (which has been working pretty well) and a local URI blacklist in which to put my own domains that I have problems with. Since I find it hard to believe I am the only one wanting to do this, I can only assume I must have missed the how-to somewhere along the way. Can anyone lend a hand, or provide some links on how I can add in my own list?

I will be somewhat away from email for a few days. May be able to check in on and off. My hosting company knows how to reach me at support at supranet.net if there are any emergencies. Jeff C.

This is a suggestion for Erik Kolve, who is the author of SpamCopURI. SURBLs themselves are only the data side of things. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

[SURBL-Discuss] multi.surbl.org combined list available for development
by Jeff Chan 16 Jun '04

16 Jun '04

I've set up a bitmasked, combined SURBL list with sc, ws, and ph data: multi.surbl.org as described earlier, except that the TXT message is customized to each entry in the list rather than generic, for example: areyoureallysatisfied.biz 600 IN A 127.0.0.6 600 IN TXT "Blocked, areyoureallysatisfied.biz on sc, ws lists, See: http://www.surbl.org/lists.html" aridanti.com 21600 IN A 127.0.0.4 21600 IN TXT "Blocked, aridanti.com on ws lists, See: http://www.surbl.org/lists.html" citi-protection.info 600 IN A 127.0.0.14 600 IN TXT "Blocked, citi-protection.info on sc, ws, ph lists, See: http://www.surbl.org/lists.html" cmbcag.biz 600 IN A 127.0.0.2 600 IN TXT "Blocked, cmbcag.biz on sc lists, See: http://www.surbl.org/lists.html" The description of multi on the Lists page has been updated to reflect this beta version of the list: http://www.surbl.org/lists.html#multi Currently this zone is served only on my name server. There is no need for any name servers to carry this zone yet since there probably won't be code to use it for a while. Hopefully it can be useful to the developers though. Once the code is written to use the combined list, we will need to get the zone out to all the name servers. I have not finished modifying my rbldnsd zone file creation script, so there is only a BIND version currently. I hope there's still some time to get support for this into the SA 3.0.0 release. The data is live, and inclusion in the combined list and other parameters are all governed from control files, so they're easy to change, for example to add future lists. Please send me any feedback, including about the proposed wording of the TXT message. Cheers, Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/
