+# haraka-plugin-dns-lists
+
+## dns lists
+
+Looks up the IP address of the remote host in a IP list(s). There are several types of DNS based lists:
+
+### block
+
+Block lists (aka: DNSBL) are designed to be used for blocking mail from any host listed in them. Block lists are the most common DNS list type and lists without a type specifier are considered block lists. The default action for block lists is the reject the connection. This can be changed by setting `reject=false` in the zone's settings block.
+
+
+### allow
+
+When the remote IP is found in an allow list, this plugin returns OK for the ehlo, helo, and mail hooks.
+
+IMPORTANT!  The order of plugins in config/plugins is important when this feature is used. It should be listed *before* any plugins that you wish to skip, but after any plugins that accept recipients.
+
+
+## INSTALL
+
+```sh
+cd /path/to/local/haraka
+npm install haraka-plugin-dns-list
+echo "dns-list" >> config/plugins
+service haraka restart
+```
+
+### Configuration
+
+If the default configuration is insufficient, copy the config file from the distribution into your haraka config dir and modify it:
+
+```sh
+cp node_modules/haraka-plugin-dns-list/config/dns-list.ini config/dns-list.ini
+$EDITOR config/dns-list.ini
+```
+
+dns-lists.ini - INI format with options described below:
+
+#### [main] periodic_checks=30
+
+Check every DNS zone every `N` minutes. When the value is less than 5, checks will only be run at start-up.
+
+The checks confirm that lists are responding correctly. When errors are detected, the zone is disabled and will be checked at the next interval. When a zone resumes working correctly it will be enabled.
+
+
+#### [main] zones
+
+An array or comma separated list of zones to query.
+
+
+#### [main] search: (default: all)
+
+- first: consider first DNSBL response conclusive. End processing.
+- all:   process all DNSBL results
+
+
+#### [stats] enable=true
+
+    To use this feature you must have installed and configured the 'redis' plugin.
+
+    When enabled, this will record several list statistics to redis.
+
+    It will track the total number of queries (TOTAL) and the average response time (AVG\_RT) and the return type (e.g. LISTED or ERROR) to a redis hash where the key is 'dns-list-stat:zone' and the hash field is the response type.
+
+    It will also track the positive response overlap between the lists in another redis hash where the key is 'dns-list-overlap:zone' and the hash field is the other list names.
+
+    Example:
+    <pre><code>redis 127.0.0.1:6379> hgetall dns-list-stat:zen.spamhaus.org
+    1) "TOTAL"
+    2) "23"
+    3) "ENOTFOUND"
+    4) "11"
+    5) "LISTED"
+    6) "12"
+    7) "AVG_RT"
+    8) "45.5"
+    redis 127.0.0.1:6379> hgetall dns-list-overlap:zen.spamhaus.org
+    1) "b.barracudacentral.org"
+    2) "1"
+    3) "bl.spamcop.net"
+    4) "1"
+    5) "TOTAL"
+    6) "1"
+    </code></pre>
+
+#### [stats] redis\_host
+
+In the form of `host:port` this option allows you to specify a different host on which redis runs.
+
+
+### Per-Zone DNS list settings
+
+The exact name of the DNS zone (as specified above in main.zones) may contain settings about that DNS list. 
+
+* type=[ block, allow, karma ]
+* reject (default: true)
+Reject connections from IPs on block lists. Setting this to false makes dnsbl informational. reject=false is best used in conjunction with plugins like [karma](/manual/plugins/karma.html) that employ a scoring engine to make choices about message delivery.
+* ipv6=true | false
