I run the Abusive Hosts Blocking List (http://www.ahbl.org). We list everything from spam sources, to spam supporters, open proxies, open relays, drones, etc. Its in use on all of the mail servers I help administrate (which includes several fortune 500 companies, half a dozen regional ISPs, and several .edu sites), plus SpamHaus, SpamCop BL, SORBS, EasyNet, and several others, which help balance out protection. A good list of all known ones is up at: http://www.declude.com/junkmail/support/ip4r.htm The only DNSbl which you really should avoid like the plague is the XBL (which I believe is gone at this point). In the various places where I've gotten a look at their spam protection, SpamHaus is very popular, as is SpamCop's BL. -------------------------- Brian Bruns The Summit Open Source Development Group Open Solutions For A Closed World / Anti-Spam Resources http://www.sosdg.org The AHBL - http://www.ahbl.org ----- Original Message ----- From: "Paul S.

I have been asked to find out what DNSBLs are in use so my employer can
see
what the incidence of its being blacklisted is and how much impact this is likely to have had on their business.
What DNSBLs are being used by the various agencies represented on NANOG and how much weighting do you give them. Are there any DNSBLs you would completely ignore due to data quality issues?
Thanks
