Django not sending emails to admins

Question

According to the documentation, if DEBUG is set to False and something is provided under the ADMINS setting, Django will send an email

Answer 1

In my case the cause was missing SERVER_EMAIL setting.

The default for SERVER_EMAIL is root@localhost. But many of email servers including my email provider do not accept emails from such suspicious addresses. They silently drop the emails.

Changing the sender email address to django@my-domain.com solved the problem. In settings.py:

SERVER_EMAIL = 'django@my-domain.com'
