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

Problems

  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits), mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    Key in test mode
    DKIM · These keys have t=y, so receivers treat DKIM failures as a test: dkim. Remove t=y once DKIM works.
    #24
  • !
    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.
