  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2017120447 on ns2.mvsrbd.net (46.17.15.250), ns2.mvsrbd.net (2a02:2870:c002:1::11); 2017120448 on ns1.mvsrbd.net (46.17.9.3), ns1.mvsrbd.net (2a02:2870:1:100:46:17:9:3); 2017120450 on ns1.rbdnet.nl (194.26.120.1), ns2.rbdnet.nl (194.26.120.2). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

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
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.rbdnet.nl
    #11
  • !
    Signatures expire in 93h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-26T12:40:00Z (in 93h0m0s). 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.
    #32
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
    #35
  • !
    Not all MX hosts use DANE
    TLS · These MX hosts publish no TLSA records, so mail to them is not protected by DANE: fallback.server01.slaveserver.net.
