DMARC (Domain-based Message Authentication, Reporting & Conformance) helps protect your domain from email spoofing and phishing. When you enable DMARC on your domain, email providers like Gmail, Outlook, and Yahoo send you aggregate reports showing: - Who's sending email claiming to be from your domain - Which emails passed or failed authentication (SPF/DKIM) - How many emails were sent, and from which IP addresses - Whether malicious actors are trying to impersonate your domain The Problem: These reports arrive as compressed XML attachments in your inbox - nearly impossible to read or analyze manually. The Solution: Parse DMARC automatically fetches these reports from your inbox, parses them, and displays everything in a beautiful dashboard. All in a single 14MB Docker image.
