Managing DMARC aggregate and feedback reports

Managing DMARC aggregate and feedback reports

Designed to quickly and easily manage DMARC aggregate and feedback reports.

Description

This Django DMARC project aims to ease implementating DMARC “Domain-based Message Authentication, Reporting & Conformance” and ongoing monitoring by importing aggregate and feedback reports about messages that pass and/or fail DMARC evaluation into a more easily digested format.

Perhaps one of the main reasons DMARC is gaining traction amongst organisations of all sizes is a desire to protect their people, brand and reputation. By defining and implementing a DMARC policy, an organization can help combat phishing, protect users and their reputation.

At beta stage, the application is stable, with most efforts on improving usability and documentation.

Choosing Django was an easy choice as it offers an easily built import mechanism and transformation from xml to database through to presentation.

Although it has options for importing either xml or email files, zero maintenance is achieved by fully automating import of feedback and reports.

Quick start

1. Install the app

2. Add “dmarc” to your INSTALLED_APPS setting:

   INSTALLED_APPS = (
       ...
       'dmarc',
   )

3. Add dmarc.urls to your urls:

   from dmarc import urls as dmarc_urls
   
   urlpatterns = [
       ...
       url(r"^dmarc/", include(dmarc_urls)),
   ]

4. Run ‘python manage.py migrate’ to create the database models.

5. Import a report with:

   python manage.py importdmarcreport --email

6. See your aggregated feedback reports from the Admin page at admin/dmarc

Usage

python manage.py importdmarcreport –email

You can choose to import an xml or email file, alternatively with “–email -” you can pipe an email and it will do the right thing.

Installation

Install the app

Configuration

Add “dmarc” to your INSTALLED_APPS setting:

INSTALLED_APPS = (
    ...
    'dmarc',
)

Add dmarc.urls to your urls:

from dmarc import urls as dmarc_urls

urlpatterns = [
    ...
    url(r"^dmarc/", include(dmarc_urls)),
]

DMARC reports are namespaced so if you’re using django version 1.8 you will need to add the namespace ‘dmarc’:

urlpatterns = [
    ...
    url(r"^dmarc/", include(dmarc_urls, namespace='dmarc')),
]

Install tables

Run ‘python manage.py migrate’ to create the database tables.

Import feedback report

Import an email DMARC aggregate report with:

python manage.py importdmarcreport --email

Alternatively the xml report can be imported with:

python manage.py importdmarcreport --xml

The process of importing DMARC aggregate reports can be fully automated. At Persistent Objects we use Exim and the configuration couldn’t be easier.

Router:

dmarcreports:
    driver = accept
    condition = ${if eq{$local_part}{dmarc_report}}
    transport = trans_dmarcreports

Transport:

trans_dmarcreports:
    driver = pipe
    command = "/usr/local/bin/python2.7 /path/to/manage.py importdmarcreport --email -"
    freeze_exec_fail = true
    return_fail_output = true

Congratulations, you have django-dmarc installed and ready to import DMARC aggregate feedback reports and start implementing DMARC and protecting your emails.

DMARC reporting

Aggregated feedback reports are available from the Admin page at admin/dmarc.

From the DMARC dashboard at ‘Site administration/DMARC’ where the intention is to highlight a summary of recent reports, there is one report ‘DMARC feedback reports’ and is available to any user with staff members authorization.

This is an example report, it can also be downloaded as a csv file suitable for importing into your favourite spreadsheet.

The report can be filtered by clicking on the filter and changing any of the reporting period, only showing errors/failures, disposition (quarantine, rejection or any) and by source ip address/reporting organisation.

These reports can help ease any DMARC implementation.

Maintenance

Although there is usually no need to remove old records, access to the report table is offered to allow for record deletion.
