    Severity: Medium
    Detail: The "all" mechanism at the end of the end of an SPF record tells receivers how to treat unauthorised (i.e. spoofed) emails - the "~all" setting tells receivers to 'SoftFail' (i.e. quarantine) emails that fail SPF authentication. In practice however, many email filters only slightly raise the total spam score and accept 'SoftFailed' (i.e. spoofed) emails.
