check_domainread-only | Audit the email-authentication DNS records of a domain. Returns a 0–100 score and A–F grade (MX 10, SPF 25, DMARC 30, DKIM 25, BIMI 10, plus up to 5 bonus points for MTA-STS and TLS-RPT, capped at 100), each check's status, published record, findings and recommended fixes, and a link to the full report. Read-only: it only queries public DNS and the domain's public MTA-STS policy file. Same engine and scoring as the DnsGuard JSON API (GET /api/check). |
