Problems

  • !
    Signatures expire soon
    DNSSEC · The earliest signature expires at 2026-10-29 00:00 UTC (in 153h0m0s). Check that automatic re-signing works.
    #30
  • !
    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.

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
  • !
    Signatures expire in 153h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-29T00:00:00Z (in 153h0m0s). Check that re-signing works.
    #21
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (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:reports@debuginc.com (needs metabolic.nl._report._dmarc.debuginc.com). 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.
