Uncaught error for DMARC query when ignoring unrelated records #130

Closed FestiveKyle closed 1 month ago

FestiveKyle commented 3 months ago

There is an uncaught error when ignoring unrelated records during the DMARC check if there is no DMARC record present. 

    "dmarc": {
        "record": null,
        "valid": false,
        "location": null,
        "error": "list index out of range"
    },

Stems from here in dmarc.py:

        dmarc_record = [record for record in records if record.startswith(
            txt_prefix)][0]
