django-dkim

DKIM signing is generally better left to the mailserver. However, there are situations when you are unable to configure the SMTP server you use for sending mail. If you still want to sign your messages with DKIM, you can do it manually, on the application level.

This library provides custom e-mail backends with DKIM signing for Django web framework. Singing itself is provided by dkimpy library.

Installation

You can install stable version of django-dkim from PyPi:

$ pip install django-dkim

Settings

In order to use this custom backends, you have to add a few configuration options into your Django settings.

• EMAIL_BACKEND — dotted path to custom e-mail backend
• DKIM_SELECTOR — string containing DKIM selector
• DKIM_DOMAIN — string containing DKIM domain
• DKIM_PRIVATE_KEY — string containing whole private key (including the header)

Note: This library is not Django application, so you don't need to change your INSTALLED_APPS setting.

Example

EMAIL_BACKEND = 'django_dkim.backends.smtp.EmailBackend'
DKIM_SELECTOR = 'selector'
DKIM_DOMAIN = 'example.com'
DKIM_PRIVATE_KEY = '''-----BEGIN RSA PRIVATE KEY-----

This project is pretty small and self-contained, but I'm willing to add features, if they are useful. If you have an idea, bugfix, or really anything, please create Issue on GitLab. Don't create GitHub issues — the GitHub repo is only a mirror of GitLab, where real development happens.
