It really depends on the setting (school, ISP, business, home, etc.), but the only one I generally recommend is sbl-xbl.spamhaus.org. The only other one that catches significant spam for me is relays.ordb.org, but it catches much less than sbl-xbl. The Spamcop BL is probably fine for home or hobbyist use at the MTA level, but it's probably too inclusive for use by an ISP, for example. Barring exclusions by SpamCop any sender that any SpamCop user reports gets listed. That's counting a bit too much on SpamCop users not making mistakes in their submissions. BTW you don't need to use cbl.abuseat.org separately since it's included in xbl.spamhaus.org, which in turn is included in sbl-xbl. RBLs are also used in some SpamAssassin rules to build up scores. That's arguably a better use for most of the RBLs, some of which have pretty high false positive rates. In SpamAssassin they're typically not used to block outright, but to increase the scores to indicate a degree of spammyness. An advantage is that false positives on any particular list can contribute less to blocking a ham (a wanted message). Jeff C. -- Jeff Chan mailto:[EMAIL PROTECTED] http://www.surbl.org/
