NSEC3 with extra iterations or salt

DNSSEC · NSEC3 uses 1 iteration and a 1-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

!

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
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: fallback1.mx.nxs.nl, fallback2.mx.nxs.nl

#11
!

Applies to 75% of mail

DMARC · DMARC policy only applies to 75% of failing mail (pct=75). Raise pct to 100 once you are confident in your setup.

#18
!

1024-bit DKIM key

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector2 (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.
