rblcheck

Tool to query DNSBL servers

This program is a very basic interface to DNS Blackhole Lists. The basic idea of the filter is that when someone is blacklisted for email abuse of some sort, a new domain name is resolved of the form "2.0.0.127.domain.name.com", where 2.0.0.127 is the abusive IP address in reverse (for example, 2.0.0.127 would be the IP address 127.0.0.2), and "domain.name.com" is the base domain name of the filtering service.
