modoboa-dmarc

A set of tools to use DMARC through Modoboa.

This feature 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

Note

modoboa-installer can automatically set it up for you.

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

Debian / Ubuntu
libmagic1

CentOS
file-devel

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:

Note

You must not declare this email address as an identity (user account or alias), else DMARC reports will be directed to your mailbox and won’t be parsed.

Hash the file using the following command:

$ postmap /etc/postfix/dmarc_transport

Finally, reload postfix:

$ service postfix reload
