OK. Thanks for the info. I've also googled a little and found that: Here the lists I've read about and some explanations on "why should I use them". The following bl's would be recommended that doesn’t enlist half of the Internet (for instance all dialups in the world) in one overnight - 1) sbl-xbl.spamhaus.org 2) safe.dnsbl.sorbs.net 3) list.dsbl.org 4) cbl.abuseat.org - XBL has some delay until updates are propagated from CBL, so querying XBL first and then CBL gives you two advantages: * You profit from the high reliability and low response times of Spamhaus' DNS setup * After SBL-XBL filtered out the bulk, CBL can kick in to "catch the rest", ie those not yet propagated from CBL to XBL. 5) dnsbl.njabl.org - as stated here " http://www.spamhaus.org/xbl/index.lasso"; Mail servers already using dnsbl.njabl.org are advised to continue doing so, as dnsbl.njabl.org is itself a composite list and contains more than the open proxy IPs list part now incorporated in XBL What about those 4 lists? Anyone have any experience with them?: blackholes.easynet.nl will-spam-for-food.eu.org zen.spamhaus.org zombie.dnsbl.sorbs.net P.S.: Policyd-weight indeed sounds very interesting, as Henrik stated. Any usage experience?
