CONFIGURATION

        "DMARC" : {                                      | Config for the DMARC Module
                                                         | Requires DKIM and SPF
            "hard_reject"         : 0,                   | Reject mail which fails with a reject policy
            "no_list_reject"      : 0,                   | Do not reject mail detected as mailing list
            "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"
            ],
            "hide_none"           : 0,                   | Hide auth line if the result is 'none'
            "detect_list_id"      : "1",                 | Detect a list ID and modify the DMARC authentication header
                                                         | to note this, useful when making rules for junking email
                                                         | as mailing lists frequently cause false DMARC failures.

            ],
