What is an email security check?
An email security check reads the DNS based policies that decide whether a message claiming to come from a domain is genuine. SPF, DKIM, and DMARC together stop attackers from spoofing a domain to send phishing or fraud. digga inspects all of them, plus MTA-STS, TLS-RPT, and BIMI, and turns the result into a clear picture of how well the domain is protected.
