SPF for optonline.net
optonline.net publishes an SPF record; it authorises 1 included sender list, and the record ends in ~all (soft fail): mail from unlisted servers is marked suspicious but usually still delivered.
DMARC for optonline.net
optonline.net 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 optonline.net. 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.
