I prefer to call them DNSBLs, as RBL is a proper name (of MAPS RBL). For those of you who are afraid about reliability of a DNSBL, I can highly recommend cbl.abuseat.org as the absolute minimum. This list (called CBL for short) has the following properties: * Takes its data from very large spamtraps. * Only lists IPs which are open-proxy-like. * Only lists individual IPs, never lists "IP ranges". * It's completely automated to prevent human error. * Tries very hard not to list "real" SMTP servers. * Everybody can remove any IP from the list without any questions at all. and last, but not least important: * You can avoid approximately 50% of all the spam just by using this list. So I would call the CBL a very useful list. BTW: I'd like to thank Ryan for the db.debian.org stuff and share my happiness with everybody here: I enabled zen.spamhaus.org and greylisting on 2006-12-31. Now I receive just three spams a day instead of 150 spams a day. Hurrah! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
