http://www.email-policy.com/Spam-black-lists.htm Has many more. As for spamhaus, I would say 10% is low ... even if just for the SBL list alone. There is also the XBL list which incorporates : - the CBL (Composite Block List) from cbl.abuseat.org - the BOPM (Blitzed Open Proxy Monitor) from opm.blitzed.org - the NJABL open proxy IPs list from www.njabl.org. And the sbl-xbl list which incorporates both. sbl-xbl.spamhaus.org for the RBL entry in your mail server. With that RBL entry and a couple of others (like open relays, and spamcop.net), your spam reduction would be much much greater than 10% for sure. > 2) SpamAssassin ( identifies about 30% of spam ) I would suspect that would be correct using the default installation, and settings. It becomes a much more efficient, and powerful tool if you add additional rule sets : http://wiki.apache.org/spamassassin/CustomRulesets http://www.rulesemporium.com/rules.htm It also depends on how SA is setup. Whether running globally, or per user, or through a milter (like amavis). Amavis overrides the SA globals, and has it's own configurations (which are defaulted to higher values than SA distributed). You have to tweak things for your setup ... there is no one answer. In addition to that SA provides learning system. You can "teach" SA to learn better what is SPAM by forcing a read, and also changing your false-positive matches into HAM by running a cron job, or some other means. It is somewhat self learning by default as I recall. > 3) Spam bait ( blocks about 40% of spam ) > never used it, can't say.
