SPF for yahoo.com.mx
yahoo.com.mx publishes an SPF record; it names its senders directly rather than through include mechanisms, and the record has no explicit all mechanism, so receivers treat unlisted servers as neutral.
DMARC for yahoo.com.mx
yahoo.com.mx 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 yahoo.com.mx. 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.
