Consolide your "DMARC" reports!

The Problem

The DMARC reports are received on email attachments in XML format (compressed). I don't know a default viewer and we receive one file by day by external domain. I needed join the data and build a visual report.

The Solution

I decided build a script that:

• Access the dmarc mail account
• Reads the messages
• Extracts the attachments and
• consolidate the data to show some graphs in a webserver.

Instructions

Install the project

git clone https://github.com/hitalos/dmarc-report
npm i --only=production

Install for express as a middleware

npm i dmarc-report

Configuration

Copy or rename .env-example to .env and set the values to your environment.

Use a exclusive account to this or choose a folder in your account, move the reports to it and set it to IMAP_FOLDER.

Running as standalone app

npm start

Using as a middleware

Example:

const express = require('express')
const dmarc = require('dmarc-report')

const app = express()
app.use('/dmarc', dmarc)
app.listen(3000)

SERVER_PORT has no effect when running as a middleware

Certify yourself that expose environment variables or use dotenv module to load it.

.env example:

IMAP_HOST=yourdomain.com
IMAP_USER=dmarc
IMAP_PASS=password
IMAP_FOLDER=INBOX
IMAP_READ_ONLY=1
SERVER_PORT=3000
