Problems

!

NS sets differ

Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns.zxcs.be. ns.zxcs.be, ns.zxcs.eu, ns.zxcs.nl report NS ns.zxcs.eu ns.zxcs.nl.

#7
!

Unusual SOA timers

SOA · refresh 10m is outside 20m–1d; retry 1h should be shorter than refresh 10m. Current values: refresh 10m, retry 1h, expire 14d, negative TTL 1d.

#23
!

Very low TTLs

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m40s), MX (1m40s), NS (1m40s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m40s; resolvers may use either.

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
!

No aggregate reports (rua)

DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...

#19
!

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.
