Field notes
The checker reports MX, SPF, DMARC, and five common DKIM-selector results as pass, warn, or fail; the page says it does not retain the domain name. Its guides recommend a cautious DMARC rollout, starting at p=none and reviewing reports before tightening the policy. Three listings are marked “Made by us,” while the directory says any purchased sponsor placements will be labeled.
