What this checker tests

It checks the four DNS areas most often involved in spoofing protection and mail-delivery failures.

  • SPF: verifies that exactly one SPF policy is published.
  • DKIM: checks the public key at the selector supplied by your mail provider.
  • DMARC: identifies missing, monitoring-only, quarantine, or reject policies.
  • MX: confirms that mail exchangers are published.
