Problems

!

No IPv6

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

#13
!

Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns165.axc.nl: "9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.16.tuxcare.els18"; ns166.axc.nl: "9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.16.tuxcare.els18". Hide or replace the version string.

#17
!

Unusual SOA timers

SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 14d, negative TTL 1d.

Problems

!

Policy: quarantine

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

#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
!

Applies to 10% of mail

DMARC · DMARC policy only applies to 10% of failing mail (pct=10). Raise pct to 100 once you are confident in your setup.

#18
!

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.
