What is DMARC Lookup?
DMARC Lookup retrieves the DMARC policy configured for a domain. DMARC records are stored as DNS TXT records under the _dmarc.domain.com subdomain.
DMARC policies help domain owners protect their domains from phishing, spoofing and unauthorized email usage by defining how receiving mail servers should handle authentication failures.
Organizations commonly use DMARC together with SPF and DKIM to improve email security, increase deliverability and gain visibility into email authentication activity.
