关于产品
Check a domain's email authentication from DNS and get JSON back. SPF (with DNS lookup count), DMARC, DKIM, MTA-STS, TLS-RPT, BIMI and MX records are judged against the RFCs. You get coded issues, a grade (A+ to F) and a score out of 100. A second endpoint validates SPF, DMARC or DKIM record text you paste in, offline. Only DNS-over-HTTPS is used; the target's mail servers are never contacted.
