Kit Rx: Email authentication posture (SPF, DMARC, MTA-STS)
https://api.kit-rx.com/v1/domain/email-authOverview
Email authentication posture of a domain from DNS (Cloudflare DNS over HTTPS): MX records and null MX, SPF parsed into mechanisms with its all qualifier and a recursive DNS-lookup count against the RFC 7208 limit of 10, DMARC policy (p, sp, pct, alignment, report addresses' domains), MTA-STS and TLS-RPT records, and BIMI. DKIM is not assessed because selectors cannot be enumerated. Returns an A-F grade and 0-100 score with weighted reasons.
