    "whitelisted"           : [                    | A list of ip addresses or CIDR ranges, or dkim domains
        "10.20.30.40",                             | for which we do not want to hard reject mail on fail p=reject
        "dkim:bad.forwarder.com",                  | (valid) DKIM signing domains can also be whitelisted by
        "20.30.40.0/24"                            | having an entry such as "dkim:domain.com"
    ],
    "use_arc"             : 1,                     | Use trusted ARC results if available
