Configuration of email delivery with Mailgun


The server supports multiple email providers. This guide will explain how to configure the Psono server to use Mailgun for email delivery.


During the installation of the server you have created a settings.yaml that needs to be adjusted now.

  1. Configure email address

    EMAIL_FROM: '[email protected]'

    All emails that are sent by the server will come from this email address.

  2. Add Mailgun API credentials to setting.yml

    EMAIL_BACKEND: 'anymail.backends.mailgun.EmailBackend'

    Replace MAILGUN_ACCESS_KEY with the API key that was provided to you by Mailgun.

  3. EMAIL_FROM’s domain and Mailgun’s domain differ

    If you are want to use an email address with a domain that does not match the one that you configured with Mailgun, you can configure here a different one.


    Replace MAILGUN_SERVER_NAME with the domain that you registered with Mailgun. This is only required if your Maingun sender domain is different from your EMAIL_FROM’s domain. This setting is not needed if the domain of EMAIL_FROM matches the one from Mailgun.

  4. (optional) EU Server

    If you are using the EU server, you have to specify in addition



To send a test email to [email protected] execute:

python3 ./psono/ sendtestmail [email protected]

or with docker:

docker run --rm \
  -v /path/to/modified/settings.yaml:/root/.psono_server/settings.yaml \
  -ti psono/psono-server:latest python3 ./psono/ sendtestmail [email protected]

If you receive this test email, then email should be configured proper.
