This may eventually be replaced by an UDP client that is built + directly into the <a href="postscreen.8.html"><b>postscreen</b>(8)</a> server. + +<b>PROTOCOL</b> + With each connection, the <a href="dnsblog.8.html"><b>dnsblog</b>(8)</a> server receives a DNS white/black- + list domain name, an IP address, and an ID. If the IP address is + listed under the DNS white/blacklist, the <a href="dnsblog.8.html"><b>dnsblog</b>(8)</a> server logs the + match and replies with the query arguments plus an address list with + the resulting IP addresses, separated by whitespace, and the reply TTL. + Otherwise it replies with the query arguments plus an empty address + list and the reply TTL; the reply TTL is -1 if there is no reply, or a + negative reply that contains no SOA record. Finally, the <a href="dnsblog.8.html"><b>dnsblog</b>(8)</a> + server closes the connection. + +<b>DIAGNOSTICS</b> + Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>. + +<b>CONFIGURATION PARAMETERS</b> + Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as <a href="dnsblog.8.html"><b>dnsblog</b>(8)</a> processes + run for only a limited amount of time.
