You can use a DMARC Analyzer—specifically DMARCReport—by publishing a DMARC record that sends RUA/RUF reports to DMARCReport, then using its dashboard, alignment checks, alerts, and policy controls to identify spoofing sources quickly and move from monitoring (p=none) to enforcement (quarantine/reject). Context and background Email domain spoofing happens when attackers send messages with your domain in…
