Parse DMARC reads the DMARC aggregate reports that Google, Microsoft, and Yahoo email about your domain every day and shows you, in one dashboard, who is sending mail as you and whether it passes authentication. It fetches the reports over IMAP, unpacks the gzip, zip, and XML attachments automatically, and charts your pass rate, message volume, and top sending sources at a glance. Any report opens down to its raw records, so when an unfamiliar IP starts sending as you, the evidence is one click away instead of buried in XML. Reports forwarded through Exchange or Outlook as message attachments are unwrapped too, and a local Maildir intake covers servers where the mailbox lives on the same host. A built-in generator writes your _dmarc TXT record from a form, so tightening your policy does not mean hand-writing DNS syntax from memory. Twenty-eight Prometheus metrics and a shipped Grafana dashboard move the same data into the monitoring stack you already run. An MCP server lets an AI assistant query your reports directly, asking which sources failed DKIM this week in plain language. Everything stores in a single SQLite file inside one static Go binary, with dark mode for late-night incident reviews.
