What is Rblchecks
Rblchecks is a small daemon which emulates a DNS server. Clients eg. smtp servers (by their DNS servers) may query it to know whether a host (by its reversed IP address) is blacklisted or not.
Rblchecks listens on port 53/udp (not on 53/tcp) and waits for queries. And responses with a 'host not found' message or with the IP address 127.0.0.2 if the queried IP address is blacklisted.
