URIDNSBL

Do not use free public DNS servers like Google DNS, OpenDNS or Level3 for nameservers in your servers /etc/resolve.conf when using this plugin. We recommend using a caching DNS server locally.

This plugin by analysing message text and HTML for URLs, extracting host names from those, then querying various DNS blocklists for either: IP addresses of these hosts (uridnsbl,a) or their nameservers (uridnsbl,ns), or domain names of these hosts (urirhsbl), or domain names of their nameservers (urinsrhsbl, urifullnsrhsbl).
