Problems

!

Software version disclosed

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

#17
!

Not signed

DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

#27
!

Very low TTLs

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (34s), AAAA (30s). Low TTLs are useful just before a planned change.

Problems

✗

Policy: none (monitoring only)

DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

#4
!

No key under common selectors

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

#7
!

Not enabled

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

#8
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: charlie.mx.blackflow.eu, delta.mx.blackflow.eu

#11
!

Policy in testing mode

TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.
