Email authentication
Spoofing protection has gaps that need attention.
Authorizes which servers may send mail for the domain
No SPF record. Receivers cannot tell which servers may send as this domain.
Cryptographically signs outgoing mail (best-effort selector probe)
DKIM key published for 1 known selector.
Tells receivers what to do with mail that fails SPF and DKIM
No DMARC record. Failing mail is not actively rejected or quarantined.
Enforces TLS for inbound mail and prevents downgrade attacks
No MTA-STS policy. Inbound mail can be delivered without TLS.
Receives reports about TLS delivery failures
No TLS-RPT record. You get no reports about failed TLS delivery.
Displays your verified brand logo in supporting inboxes
No BIMI record. No brand logo is published for inboxes.
Checks query live DNS over Cloudflare and the public MTA-STS policy endpoint. DKIM selectors cannot be listed from DNS, so DKIM detection probes common provider selectors only.
