django_mailgun.MailgunBackend does NOT send Django's errors via email

Question

I had an issue trying to send Django's Errors via email. Mailgun's logs are completely empty for this domain!

Hacking django_mailgun.py revealed <Response 400> from mailgun which fails silently.

Why django_mailgun.py does not work ?

Answer 1

When SERVER_EMAIL is not defined in settings.py, Django sends errors from "root@localhost" which does NOT work for Mailgun anymore and produces <Response400>

So i have added:

SERVER_EMAIL = 'postmaster@my-domain.com'

to settings.py
