I add it in ‘lms.env.json’

EDXAPP_ACE_CHANNEL_DEFAULT_EMAIL: "django_email"
EDXAPP_ACE_CHANNEL_SAILTHRU_DEBUG: false
EDXAPP_ACE_CHANNEL_SAILTHRU_TEMPLATE_NAME: "template"
EDXAPP_ACE_CHANNEL_TRANSACTIONAL_EMAIL: "django_email"
EDXAPP_ACE_ENABLED_CHANNELS: ["django_email"]
EDXAPP_ACE_ENABLED_POLICIES: ["bulk_email_optout"]
EDXAPP_DEFAULT_FROM_EMAIL: “hello@example.org”
EDXAPP_EMAIL_BACKEND: “django.core.mail.backends.smtp.EmailBackend”
EDXAPP_EMAIL_HOST: “localhost”

Want to modify Django as the sending mail backend of ACE; But it doesn’t work. Why is that? Is there any problem with my configuration information? Or am I missing something.
