Problems

  • ✗
    11 DNS lookups, over the limit of 10
    SPF · SPF record needs 11 DNS lookups (including nested includes), more than the limit of 10. Receivers will return a permerror; reduce includes or flatten the record.

  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx1-eu1.ppe-hosted.com, mx2-eu1.ppe-hosted.com
    #11
  • !
    Applies to 5% of mail
    DMARC · DMARC policy only applies to 5% of failing mail (pct=5). Raise pct to 100 once you are confident in your setup.

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits), k1 (1024 bits), s2 (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.
