DMARC Analyzer
Monitor email authentication, catch spoofing, and advance your domains safely toward enforcement — all from one self-hosted dashboard.
This tool ingests DMARC aggregate reports from your mailbox, parses them, enriches source IPs, and surfaces pass/fail trends, unknown senders, and concrete recommendations per domain.
DMARC aggregate reports are the authoritative evidence base for understanding who is sending as your domain and whether authentication is working. This tool makes that data actionable without requiring manual XML parsing or a third-party SaaS.
It's built for operators running a handful of domains on their own infrastructure, who want visibility and a safe path toward p=reject without handing report data to an external service.
Ingestion
Polls your DMARC mailbox automatically; tolerates vendor XML deviations and hostile input.
Enrichment
Labels source IPs as known infrastructure or unknown senders via rDNS, ASN, and your allowlist.
Recommendations
R1-R12 rule engine turns report data into prioritized, evidence-backed action items.
Health checks
Probes SPF, DKIM, DMARC, MX, DNSSEC, MTA-STS, TLS-RPT, blocklists, and more on demand.
Alerting
Daily digest flags heartbeat failures, policy drift, unknown-sender spikes, and pass-rate drops.
