Problems

  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns.icodia.com (46.31.192.40): dial tcp 46.31.192.40:53: i/o timeout.
    #19
  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IP addresses
    MX · The following MX hosts could not be resolved to IP addresses: mx0.mailinblack.com
    #10
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: asp17.mailinblack.com, mx0.mailinblack.com
    #11
  • !
    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
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 52.143.158.11 (asp17.mailinblack.com). Ask your hosting provider to set one.
    #30
  • !
    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.
