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

Problems

  • !
    Ends with ?all (neutral)
    SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.
    #3
  • !
    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
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), google (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.
