Do not use free public DNS servers like Google DNS, OpenDNS or Level3 for nameservers in your servers
/etc/resolve.confwhen 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).
