!

Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: robert.ns.cloudflare.com: "2026.10.2"; sloan.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

#17
!

Signed but not delegated securely

DNSSEC · The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

Problems

✗

12 DNS lookups, over the limit of 10

SPF · SPF record needs 12 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.

#2
✗

No DMARC record

DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

#5
!

Signed, but no DS at parent

DNSSEC · The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.

#8
!

Single MX host, no backup

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

#12
!

Not configured

TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
