No IPv6

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

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
✗

DMARC not strict enough for BIMI

BIMI · Mail clients will not show the logo. BIMI requires DMARC p=quarantine or p=reject (now p=none), a subdomain policy other than sp=none.

#39
!

Hosts without IPv6

MX · The following MX hosts could not be resolved to IPv6 addresses: suffix01.hro.nl, suffix02.hro.nl, suffix03.hro.nl, suffix04.hro.nl, suffix05.hro.nl, suffix06.hro.nl

#11
!

More than 5 MX records

MX · Found 6 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.

#13
!

Signatures expire in 87h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-26T05:11:57Z (in 87h0m0s). Check that re-signing works.

#21
!

1024-bit DKIM key

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector2 (1024 bits). Rotate to a 2048-bit key.

#23
!

Policy in testing mode

TLS · With mode: testing, senders only report TLS problems (via TLS-RPT) and still deliver without TLS. Switch to mode: enforce once reports are clean.

#33
!

No certificate (a=)

BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
