SPF for frontier.com

frontier.com publishes an SPF record; it authorises 7 included sender lists, and the record ends in ~all (soft fail): mail from unlisted servers is marked suspicious but usually still delivered.

DMARC for frontier.com

frontier.com has DMARC in monitoring mode (p=none). Receivers report what they see but deliver failing mail anyway, so the record protects nothing yet.

Why it matters

Receivers use SPF, DKIM, and DMARC together to decide whether a message really came from frontier.com. A domain with a strict SPF record and an enforcing DMARC policy is hard to spoof and easier to deliver for; one without either is neither. Spaw reports has_spf and dmarc_policy on every lookup and adds a small risk weight when SPF is missing.
