Problems

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx01.hornetsecurity.com, mx02.hornetsecurity.com, mx03.hornetsecurity.com, mx04.hornetsecurity.com
    #11
  • !
    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: selector1 (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.
