com.blackveilsecurity/dns · Verify this server

Look up and validate the DMARC record for a domain. Shows the enforcement level (none/quarantine/reject), alignment mode (strict/relaxed), and aggregate/forensic reporting destinations. Use to determine a domain's DMARC enforcement level, whether it sends aggregate reports, or if it is protected against email impersonation — distinct from check_shadow_domains (which checks TLD variants) and assess_spoofability (composite score). Part of the scan_domain audit.
