The rise of spam and other anti-social behavior on the Internet has
led to the creation of shared DNS-based lists ("DNSBLs") of IP
addresses or domain names intended to help guide email filtering.
This memo summarizes guidelines of accepted best practise for the
management of public DNSBLs by their operators as well as for the
proper use of such lists by mail server administrators (DNSBL users),
and it provides useful background for both parties. It is not
intended to advise on the utility or efficacy of particular DNSBLs or
the DNSBL concept in general, nor to assist end users with questions
