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
!

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.

Signatures expire in 87h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-26T04:46:26Z (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), selector1 (1024 bits). Rotate to a 2048-bit key.

#23
!

Report address not authorized

DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:dmarc-reports@hr.nl (needs hro.nl._report._dmarc.hr.nl). Ask the report provider to publish the record, or check the address.

#29
!

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.
