SPF for btinternet.com
btinternet.com publishes an SPF record; it authorises 2 included sender lists, and the record ends in ~all (soft fail): mail from unlisted servers is marked suspicious but usually still delivered.
DMARC for btinternet.com
btinternet.com enforces DMARC at p=reject, so messages that fail alignment are dropped by receivers rather than delivered or quarantined. That is the end state most domains work towards.
Why it matters
Receivers use SPF, DKIM, and DMARC together to decide whether a message really came from btinternet.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.
