✗

Signatures expired

DNSSEC · The DNSSEC signatures expired at 2026-04-04 19:00 UTC; validating resolvers reject the zone.

#30
!

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.

#27
!

NSEC3 with extra iterations or salt

DNSSEC · NSEC3 uses 0 iterations and a 8-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.

✗

Signatures expired

DNSSEC · DNSKEY signatures expired at 2026-04-04T19:00:00Z. Validating resolvers will fail to resolve this domain.

#21
!

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
!

1024-bit DKIM key

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.

#23
!

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.
