SYNOPSIS
        loadplugin Mail::SpamAssassin::Plugin::DNSEval
        rbl_headers EnvelopeFrom,Reply-To,Disposition-Notification-To
        header     RBL_IP    eval:check_rbl_headers('rbl', 'rbl.example.com.', '127.0.0.2')
        describe   RBL_IP    From address associated with spam domains
        tflags     RBL_IP    net
        reuse      RBL_IP
        Supported extra tflags from SpamAssassin 3.4.3:
         domains_only - only non-IP-address "host" components are queried
         ips_only - only IP addresses as the "host" component will be queried
DESCRIPTION
       The DNSEval plugin queries dns to see if a domain or an ip address
       present on one of email's headers is on a particular rbl.
USER PREFERENCES
       The following options can be used in both site-wide ("local.cf") and
       user-specific ("user_prefs") configuration files to customize how
       SpamAssassin handles incoming email messages.
       rbl_headers
            This option tells SpamAssassin in which headers to check for content
            used to query the specified rbl.
            If on the headers content there is an email address, an ip address
            or a domain name, it will be checked on the specified rbl.
            The configuration option can be overridden by passing an headers list as
            last parameter to check_rbl_headers.
            The default headers checked are:
       o   EnvelopeFrom
       o   Reply-To
       o   Disposition-Notification-To
       o   X-WebmailclientIP
       o   X-Source-IP
       check_rbl_from_domain
           This checks all the from addrs domain names as an alternate to
           check_rbl_from_host.  As of v3.4.1, it has been improved to include
           a subtest for a specific octet.
       check_rbl_ns_from
           This checks the dns server of the from addrs domain name.  It is
           possible to include a subtest for a specific octet.
       check_rbl_rcvd
           This checks all received headers domains or ip addresses against a
           specific rbl.  It is possible to include a subtest for a specific
           octet.
