Nameservers not responding

Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.mindef.nl (2a04:8f80:2107:2002::10): read udp [2a01:4f8:1c1c:eebf::1]:44356->[2a04:8f80:2107:2002::10]:53: i/o timeout.

NSEC3 with extra iterations or salt

DNSSEC · NSEC3 uses 10 iterations and a 3-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Problems

!

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

Single MX host, no backup

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

Signatures expire in 92h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-26T10:45:02Z (in 92h0m0s). Check that re-signing works.

#21
!

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.

#32
!

Not configured

TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
