Mail::SpamAssassin::PlUser:ContributedMaPiel::SpamAssassin::Plugin::URIDNSBL(3pm)



NAME
       URIDNSBL - look up URLs against DNS blocklists

SYNOPSIS
         loadplugin    Mail::SpamAssassin::Plugin::URIDNSBL
         uridnsbl      URIBL_SBLXBL    sbl-xbl.spamhaus.org.   TXT

DESCRIPTION
       This works by analysing message text and HTML for URLs, extracting the
       domain names from those, querying their NS records in DNS, resolving
       the hostnames used therein, and querying various DNS blocklists for
       those IP addresses.  This is quite effective.

USER SETTINGS
       uridnsbl_skip_domain domain1 domain2 ...
           Specify a domain, or a number of domains, which should be skipped
           for the URIBL checks.  This is very useful to specify very common
           domains which are not going to be listed in URIBLs.

RULE DEFINITIONS AND PRIVILEGED SETTINGS
       uridnsbl NAME_OF_RULE dnsbl_zone lookuptype
           Specify a lookup.  "NAME_OF_RULE" is the name of the rule to be
           used, "dnsbl_zone" is the zone to look up IPs in, and "lookuptype"
           is the type of lookup (TXT or A).   Note that you must also define
           a body-eval rule calling "check_uridnsbl()" to use this.

           Example:

            uridnsbl        URIBL_SBLXBL    sbl-xbl.spamhaus.org.   TXT
            body            URIBL_SBLXBL    eval:check_uridnsbl('URIBL_SBLXBL')
            describe        URIBL_SBLXBL    Contains a URL listed in the SBL/XBL blocklist

       urirhsbl NAME_OF_RULE rhsbl_zone lookuptype
           Specify a RHSBL-style domain lookup.  "NAME_OF_RULE" is the name of
           the rule to be used, "rhsbl_zone" is the zone to look up domain
           names in, and "lookuptype" is the type of lookup (TXT or A).   Note
           that you must also define a body-eval rule calling
           "check_uridnsbl()" to use this.

           An RHSBL zone is one where the domain name is looked up, as a
           string; e.g. a URI using the domain "foo.com" will cause a lookup
           of "foo.com.uriblzone.net".  Note that hostnames are stripped from
           the domain used in the URIBL lookup, so the domain "foo.bar.com"
           will look up "bar.com.uriblzone.net", and "foo.bar.co.uk" will look
           up "bar.co.uk.uriblzone.net".

           If a URI consists IP address instead of a hostname, the IP address
           is looked up (using the standard reversed quads method) in each
           "rhsbl_zone".

           Example:

             urirhsbl        URIBL_RHSBL    rhsbl.example.org.   TXT

       urirhssub NAME_OF_RULE rhsbl_zone lookuptype subtest
           Specify a RHSBL-style domain lookup with a sub-test.
           "NAME_OF_RULE" is the name of the rule to be used, "rhsbl_zone" is
           the zone to look up domain names in, and "lookuptype" is the type
           of lookup (TXT or A).

           "subtest" is the sub-test to run against the returned data.  The
           sub-test may either be an IPv4 dotted address for RHSBLs that
           return multiple A records or a non-negative decimal number to
           specify a bitmask for RHSBLs that return a single A record
           containing a bitmask of results.

           Note that, as with "urirhsbl", you must also define a body-eval
           rule calling "check_uridnsbl()" to use this.

           Example:

             urirhssub   URIBL_RHSBL_4    rhsbl.example.org.   A    127.0.0.4
             urirhssub   URIBL_RHSBL_8    rhsbl.example.org.   A    8

ADMINISTRATOR SETTINGS
       uridnsbl_max_domains N        (default: 20)
           The maximum number of domains to look up.

NOTES
       The "uridnsbl_timeout" option has been obsoleted by the "rbl_timeout"
       option.  See the "Mail::SpamAssassin::Conf" POD for details on
       "rbl_timeout".
