  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 570 on ns1.surfnet.nl (192.87.106.101), ns1.surfnet.nl (2001:610:1:800a:192:87:106:101), ns2.surfnet.nl (192.87.36.2), ns2.surfnet.nl (2001:610:3:200a:192:87:36:2); 571 on ns1.zurich.surf.net (195.176.255.9), ns1.zurich.surf.net (2001:620:0:9::1103), ns3.surfnet.nl (195.169.124.71), ns3.surfnet.nl (2001:610:0:800c:195:169:124:71). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

Problems

  • ✗
    No 'all' mechanism
    SPF · SPF record doesn't have an 'all' mechanism. Add -all or ~all at the end of your SPF record.
    #3
  • ✗
    No DKIM keys published
    DKIM · _domainkey.nhl.nl does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    Signatures expire in 95h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-26T13:45:43Z (in 95h0m0s). Check that re-signing works.
    #21
  • !
    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.
