What is a DMARC record?

A DMARC record tells receiving mail systems how to handle messages that fail aligned SPF or DKIM authentication.

How do I check a DMARC record?

Enter a domain into MailTested to look up its DMARC TXT record and review policy, coverage, reporting, and alignment settings.

What are valid DMARC policies?

The valid policies are none for monitoring, quarantine for suspicious mail, and reject for blocking failures.

Does p=none protect a domain?

A p=none policy collects monitoring data but does not ask receivers to quarantine or reject messages that fail DMARC.

📘 DMARC Checker — Frequently Asked Questions

A DMARC record tells mail servers how to handle messages that fail SPF or DKIM checks. It protects against spoofing and phishing by enforcing your policy.

It retrieves your domain’s DMARC TXT record, validates it, and displays whether your enforcement and reporting settings are correctly configured.

Valid options: p=none (monitor), p=quarantine (send to spam), or p=reject (block). Choose based on how strict you want authentication.

p=none is a monitoring policy. It can collect aggregate reports, but it does not ask receiving systems to quarantine or reject messages that fail DMARC.

📨 Why DMARC Validation Matters

DMARC ensures that fraudulent or spoofed emails using your domain are detected and handled according to your policy. Without a DMARC record, anyone can impersonate your domain, risking spam reputation and phishing exposure.

🧩 Why Use MailTested’s DMARC Checker

Unlike simple DNS lookups, MailTested interprets DMARC fields contextually — showing whether your “p” tag enforces protection and if your “rua”/“ruf” reporting is configured correctly.

It’s designed for domain admins, deliverability experts, and security teams to ensure compliance and brand integrity.
