DMARC Check
Analyze DMARC (Domain-based Message Authentication) policy configuration.
About DMARC
DMARC (Domain-based Message Authentication, Reporting and Conformance) tells receiving mail servers what to do with messages that fail SPF or DKIM checks. It also enables aggregate and forensic reporting.
DMARC Policies
- none: Monitor only, don't affect delivery
- quarantine: Mark suspicious messages as spam
- reject: Reject messages that fail authentication
