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: ns1.shockmedia.nl (31.7.0.53): read tcp 46.225.38.91:33446->31.7.0.53:53: read: connection reset by peer.
    #19
  • !
    Unusual SOA timers
    SOA · expire 4d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 3h, retry 30m, expire 4d, negative TTL 12h.

    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
