        Hi,
It looks like an issue because you probably have DEBUG=True, which will make Django use 'django.core.mail.backends.filebased.EmailBackend'. See [2].
Thanks for the hint, I've overlooked this setting and was completely focused to the django.core.mail.backends.smtp.EmailBackend setting before.
Kind regards Bjoern Franke
