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.
You can install stable version of django-dkim from PyPi:
$ pip install django-dkim
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 backendDKIM_SELECTOR
— string containing DKIM selectorDKIM_DOMAIN
— string containing DKIM domainDKIM_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.

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.
