This one has been working well for me: sbl.spamhaus.org
I wrote a little php script that parses the mail log to tell me which DNSBL is blocking the most spam so I could play with different DNSBL's and their order. After hundreds of thousands of SMTP connections, here are the DNSBL's that are most effective for me and the order I use them in: DNSBL NAME % of Spam mail blocked ---------------------------------------------------- sbl.spamhaus.org 58% blackholes.easynet.nl 26.5% bl.spamcop.net 15.5% This configuration is blocking 97% of all mail coming into my server. (Do I have a spam problem or what?) I played with every possible DNSBL order and this order worked the best for me. I don't know anything about spamhaus; like whether or not they are dependable or if they are too aggressive about blocking servers that shouldn't be blocked, etc. I am simply publishing the results that worked the best for me as far as blocking the most incoming e-mail. I can say that I haven't had any complaints about blocked e-mail other than 3 newsletters that appear to not be related to DNSBL's at all. (I service about 75 e-mail accounts). I dropped proxies.blackholes.easynet.nl and spam.dnsrbl.net because they were blocking less than 5% of the spam so I felt the extra bandwidth needed to do the query wasn't justified. If either of these DNSBL's were listed first, they still only blocked about 20% of the spam. According to my tests, using spamhaus alone will block over 75% of all spam. Since you told me the news about easynet.nl, I'm doing a test using just spamhaus and spamcop in that order. I'll publish the results when it handles a few thousand emails so the results will be statistically significant.
