modoboa-dmarc

A set of tools to use DMARC through Modoboa.

This plugin is still in BETA stage, for now it only parses XML aggregated reports and generate visual reports (using c3.js) on a per-domain basis.

Installation

Make sure to install the following additional system package according to your distribution:

Debian / Ubuntu
libmagic1

CentOS
file-devel

Install this extension system-wide or inside a virtual environment by running the following command:

$ pip install modoboa-dmarc

Edit the settings.py file of your modoboa instance and add modoboa_dmarc inside the MODOBOA_APPS variable like this:

MODOBOA_APPS = (
  'modoboa',
  'modoboa.core',
  'modoboa.lib',
  'modoboa.admin',
  'modoboa.limits',
  'modoboa.relaydomains',
  'modoboa.parameters',
  # Extensions here
  'modoboa_dmarc',
)

Run the following commands to setup the database tables:

$ cd <modoboa_instance_dir>
$ python manage.py migrate modoboa_dmarc
$ python manage.py collectstatic
$ python manage.py load_initial_data

Finally, restart the python process running modoboa (uwsgi, gunicorn, apache, whatever).

Integration with Postfix

A management command is provided to automatically parse DMARC aggregated reports (rua) and feed the database. The execution of this command can be automated with the definition of a postfix service and a custom transport table.

First, declare a new service in /etc/postfix/master.cf:

dmarc-rua-parser unix  -       n       n       -       -       pipe
  flags= user=vmail:vmail argv=<path to python> <path to modoboa instance>/manage.py import_aggregated_report --pipe

Define a new transport table inside /etc/postfix/main.cf:

transport_maps =
    hash:/etc/postfix/dmarc_transport
    # other transport maps...

Create a file called /etc/postfix/dmarc_transport with the following content:

<email address your declared in your DNS record>  dmarc-rua-parser:

Hash the file using the following command:

$ postmap /etc/postfix/dmarc_transport

Finally, reload postfix:

$ service postfix reload
