noteCertificate Transparency did not complete (HTTP 404). Results below are partial.
noteCertificate inspection is unavailable in this runtime.
noteNetwork ownership lookup is unavailable in this runtime; ASN and org are omitted.
noteCDN/WAF detection is unavailable in this runtime.
note3 hosts were identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.repeaterbook.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@repeaterbook.com"`, review the reports, then move to p=quarantine and p=reject.

CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.

Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: repeaterbook.com
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).

Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
