Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • !
    Hosts without IP addresses
    MX · The following MX hosts could not be resolved to IP addresses: mx0.mailinblack.com
    #10
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: cfp.mailinblack.com, mx0.mailinblack.com
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (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: 51.11.245.92 (cfp.mailinblack.com). Ask your hosting provider to set one.
    #30
  • !
    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.
