DNS & RHS Blackhole Lists

DNS Blackhole Lists or DNSBLs are a way to filter spam by using Domain Name Service (DNS) records as a database of policies relating to either an IP address or domain name, which can be used to decide whether or not to accept (or label) email. Don't use any of these without testing them first and reading any available listing policy. Test the DNSBLs you use regularly. If a DNSBL suddenly dies or starts to return positive results for all queries, will all of your incoming email be rejected?

The “Copy” tags in the table indictate if it is possible to use one of the following methods to take a copy of the DNS zone: A: Zone Transfer, R: RSYNC, H: HTTP, B: BGP. Links to check the lists (Chk), remove entries (Rem), add entries (Add) and to find the listing policy (Pol) are available for most lists.
