According to the documentation, if DEBUG is set to False and something is provided under the ADMINS setting, Django will send an email
The below info is given in https://docs.djangoproject.com/en/2.1/howto/error-reporting/#email-reports
EMAIL_HOST = "email host"
EMAIL_HOST_USER = "Email username"
EMAIL_HOST_PASSWORD = "Email Password"
DEBUG = False
ADMINS = (
("Your Name", "your_email@company.com")
)
In order to send email, Django requires a few settings telling it how to connect to your mail server. At the very least, you’ll need to specify EMAIL_HOST and possibly EMAIL_HOST_USER and EMAIL_HOST_PASSWORD, though other settings may be also required depending on your mail server’s configuration. Consult the Django settings documentation for a full list of email-related settings.
