+.SH NAME
+dnsblog
+\-
+Postfix DNS allow/denylist logger
+.SH "SYNOPSIS"
+.na
+.nf
+\fBdnsblog\fR [generic Postfix daemon options]
+.SH DESCRIPTION
+.ad
+.fi
+The \fBdnsblog\fR(8) server implements an ad\-hoc DNS
+allow/denylist lookup service. This may eventually be
+replaced by an UDP client that is built directly into the
+\fBpostscreen\fR(8) server.
+.SH "PROTOCOL"
+.na
+.nf
+.ad
+.fi
+With each connection, the \fBdnsblog\fR(8) server receives
+a DNS allow/denylist domain name, an IP address, and an ID.
+If the IP address is listed under the DNS allow/denylist, the
+\fBdnsblog\fR(8) 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 \fBdnsblog\fR(8) server closes the connection.
+.SH DIAGNOSTICS
+.ad
+.fi
+Problems and transactions are logged to \fBsyslogd\fR(8)
+or \fBpostlogd\fR(8).
+.SH "CONFIGURATION PARAMETERS"
