    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: princess.ns.cloudflare.com: "2026.10.2"; tony.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

Problems

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa.global.inbound.cf-emailsecurity.net, mxb.global.inbound.cf-emailsecurity.net
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 172.65.65.97 (mxa.global.inbound.cf-emailsecurity.net), 141.101.90.40 (mxb.global.inbound.cf-emailsecurity.net). Ask your hosting provider to set one.

  • !
    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:...".
