The following are DNSBLs (and other anti-spam tools) that we recommend. Being listed on this page does not necessarily mean that we use the particular DNSBL (or tool) in our own filtering. Also, some of these are better for scoring while others are appropriate for blocking. At this time, minimal commentary will be presented, but that may change in the near future. Also, please visit each web site to gain a full understanding of the licensing requirements for each of these. At various usage levels, some of these are not free or have particular requirements.

Having nothing to do with anything on this page, a friend of mine, Hunter Lack just built his web site, so I'm helping him out with some 'link juice'.
