+.SS "Verifier options"
+The
+.B verify:
+clause is used to enable or disable zone verification, configure listen
+interfaces and control the global defaults.
+.TP
+.B enable:\fR <yes or no>
+Enable zone verification. Default is no.
+.TP
+.B port:\fR <number>
+The port to answer verifier queries on. Default is 5347.
+.TP
+.B ip\-address:\fR
+Interfaces to bind for zone verification (default are the localhost
+interfaces, usually 127.0.0.1 and ::1). To bind to multiple IP addresses,
+list them one by one. Optionally, Socket options cannot be specified for verify
+ip-address
+.TP
+.B verify\-zones:\fR <yes or no>
+Verify zones by default.
+.TP
+.B verifier:\fR <command>
+When an update is received for the zone (by IXFR or AXFR) this program will be
+run to assess the zone with the update. When the program exists with a status
+code of 0, the zone is considered good and will be served. Any other status
+code will designate the zone bad and the received update will be discarded.
+The zone will continue to be served but without the update.
+.P
+.RS
+The following environment variables are available to verifiers:
+.P
+.RS
+.B VERIFY_ZONE
+.RS
+The domain name of the zone to be verified.
+.RE
+.B VERIZFY_ZONE_ON_STDIN
+.RS
+When the zone can be read from standard input (stdin), this variable is set
+to "yes", otherwise it is set to "no".
+.RE
+.B VERIFY_IP_ADDRESSES
+.RS
+The first address on which the zones to be assessed will be served.
+If IPv6 is available an IPv6 address will be preferred over IPv4.
+.RE
+.B VERIFY_PORT
+.RS
+The port number for \fBVERIFY_IP_ADDRESS\fR.
+.RE
+.B VERIFY_IPV6_ADDRESS
+.RS
+The first IPv6 address on which the zones to be assessed will be served.
+.RE
+.B VERIFY_IPV6_PORT
+.RS
+The port number for \fBVERIFY_IPV6_ADDRESS\fR.
+.RE
+.B VERIFY_IPV4_ADDRESS
+.RS
+The first IPv4 address on which the zones to be assessed will be served.
+.RE
+.B VERIFY_IPV4_PORT
+.RS
+The port number for \fBVERIFY_IPV4_ADDRESS\fR.
+.RE
+.RE
+.RE
+.TP
+.B verifier\-count:\fR <number>
+Maximum number of verifiers to run concurrently. Default is 1.
+.TP
+.B verifier\-feed\-zone:\fR <yes or no>
+Feed the updated zone to the verifier over standard input (stdin).
+.TP
+.B verifier\-timeout:\fR <seconds>
+The maximum number of seconds a verifier is allowed to run for assessing one
+zone. If the verifier takes longer, it will be terminated and the zone update
+will be discarded. The default is 0 seconds which means the verifier may take
+as long as it needs.
.SS "Pattern Options"
The
.B pattern:
.BR ixfr\-size ,
.BR create\-ixfr ,
.BR zonestats ,
+.BR outgoing\-interface ,
+.BR verify\-zone ,
+.BR verifier ,
+.BR verifier\-feed\-zone ,
and
-.B outgoing\-interface
+.B verifier\-timeout
can be given. They are applied to the patterns and zones that include
this pattern.
.SS "Zone Options"
Default no. If enabled, checks all masters for the last version. It uses
the higher version of all the configured masters. Useful if you have multiple
masters that have different version numbers served.
+.TP
+.B verify\-zone:\fR <yes or no>
+Enable or disable verification for this zone. Default is value\-zones
+configured in
+.B verify:\fR.
+.TP
+.B verifier:\fR <command>
+Command to execute to assess this zone. Default is verifier configured in
+.B verify:\fR.
+.TP
+.B verifier-feed-zone:\fR <yes or no>
+Feed updated zone to verifier over standard input. Default is
+verifier\-feed\-zone configured in
+.B verify:\fR.
+.TP
+.B verifier\-timeout: <seconds>
+Number of seconds before verifier is forcefully terminated. Specify 0 (zero)
+to not use a specific timeout. Default is verifier\-timeout from
+.B verify:\fR.
