# docker-dmarc-report [![Docker Pulls](https://img.shields.io/docker/pulls/gutmensch/dmarc-report.svg)](https://registry.hub.docker.com/u/gutmensch/dmarc-report/)

This image is intended to combine a dmarc report parser (see https://github.com/techsneeze/dmarcts-report-parser by TechSneeze.com and John Bieling) with a report viewer (see https://github.com/techsneeze/dmarcts-report-viewer/ by the same people) into a runnable docker image / microservice.

It fetches dmarc report mails regularly from an IMAP server, stores them into a MySQL DB and visualizes them via Webserver/PHP module.

## Howto
1. Create a _dmarc.example.com TXT DNS record for your domain, containg an IMAP postbox, e.g.
```
17:18 $ dig TXT _dmarc.schumann.link +short
"v=DMARC1\; p=quarantine\; fo=1\; rua=mailto:dmarc@schumann.link\; ruf=mailto:dmarc@schumann.link\; adkim=s\; aspf=s\;"
```
2. Create a MySQL Database and a user for this service
3. Run this docker image with below mentioned env vars
4. Access port 80 on the container (or 443) or put it behind a reverse proxy to view reports
```
docker pull gutmensch/dmarc-report
docker run -e ... -ti gutmensch/dmarc-report
```

New dmarc reports will be fetched every 15 minutes past the hour, every hour. Therefore it can take up to one hour for the first report to be fetched.

## Sample docker compose / Environment variables
The variables should be self-explanatory. Make sure to create the IMAP folders before the cron job runs!

**docker-compose.yml**
```yaml
version: '3.6'

services:
  dmarc-report:
    image: "gutmensch/dmarc-report:latest"
    hostname: dmarc-report
    container_name: dmarc-report
    depends_on:
      - db
    ports:
      - "80:80"
    environment:
      - "REPORT_DB_HOST=db"
      - "REPORT_DB_NAME=dmarc_report"
      - "REPORT_DB_USER=dmarc_report"
      - "REPORT_DB_PASS=dbpassword"
      - "PARSER_IMAP_SERVER_WITH_PORT=mail:143"
      - "PARSER_IMAP_USER=foobar@example.com"
      - "PARSER_IMAP_PASS=foobar"
      - "PARSER_IMAP_READ_FOLDER=Inbox"
      - "PARSER_IMAP_MOVE_FOLDER=processed"

  db:
    image: mariadb:10
    environment:
      - "MYSQL_ROOT_PASSWORD=dbrootpassword"
      - "MYSQL_DATABASE=dmarc_report"
      - "MYSQL_USER=dmarc_report"
      - "MYSQL_PASSWORD=dbpassword"
```

## Optional extended configuration
Use SSL instead of default TLS. Set both to 0 to turn off encryption. (not recommended)
```yaml
    - "PARSER_IMAP_SSL=1"
    - "PARSER_IMAP_TLS=0"
```
