  • warnSPF uses 9 of the 10 allowed DNS lookups. Adding another service may break it.
  • warnSubdomains use a weaker policy (sp=none) than the main domain (p=reject).
  • warnNo MTA-STS: mail sent to you can be downgraded to an unencrypted connection.
  • warnNo TLS-RPT record, so you won't hear about failed encrypted deliveries.
  • warnNo BIMI record (optional: shows your logo next to your emails in supporting inboxes).
  • goodSPF record found.
  • goodSPF ends with -all: servers you have not listed are rejected (hard fail).
