Why Do I Need This?
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.

- 🔒 Secure TLS support
- 🌙 Dark mode support

Quick Start
Step 1: Set Up DNS to Receive DMARC Reports
This is the most important step! Without this, you won't receive any reports to analyze.
Add a DMARC TXT record to your domain's DNS:
What this means:
p=none- Monitor only (don't block emails yet)rua=mailto:dmarc@yourdomain.com- Send aggregate reports to this email address
Important: Replace dmarc@yourdomain.com with an actual email inbox you control. This is where Gmail, Outlook, Yahoo, etc. will send your DMARC reports.
DNS Examples:
- Cloudflare: DNS > Add record > Type: TXT, Name:
_dmarc, Content:v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com - Google Domains: DNS > Custom records > TXT, Name:
_dmarc, Data:v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com - AWS Route53: Create record > Type: TXT, Name:
_dmarc.yourdomain.com, Value:"v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"
Reports typically start arriving within 24-48 hours.
Step 2: Run Parse DMARC with Docker
Run the container:
For Gmail users: You'll need an App Password, not your regular Gmail password.
Access the dashboard: Open http://localhost:8080 in your browser.
What You'll See
Once DMARC reports start arriving and Parse DMARC processes them, your dashboard will show:
- Total messages analyzed across all reports
- DMARC compliance rate (SPF/DKIM pass rates)
- Top sending sources (IP addresses and organizations sending as your domain)
- Authentication results (which emails passed/failed SPF and DKIM)
- Policy actions (how receiving servers handled your email)
