    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: cbru.br.ns.els-gms.att.net (2001:1890:1ff:9f0:68:94:156:132): read tcp [2a01:4f8:1c1c:eebf::1]:49736->[2001:1890:1ff:9f0:68:94:156:132]:53: read: connection reset by peer; cmtu.mt.ns.els-gms.att.net (2001:1890:1ff:9f1:99:99:99:132): read tcp [2a01:4f8:1c1c:eebf::1]:35768->[2001:1890:1ff:9f1:99:99:99:132]:53: read: connection reset by peer.

    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: gw141.fortimail.com
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits), selector2 (1024 bits), s1 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
