Spirit: Unable to Send Email

I’ve got this in prod_local.py

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'email host'
EMAIL_PORT = 465
EMAIL_HOST_USER = 'name@example.com'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_SSL = True

then I create a send_email_test.py:

import os
from django.core.mail import send_mail

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings.prod_local'

if __name__ == '__main__':   

    send_mail(
        'hello world',
        'welcome',
        'name@example.com',
        ['anothername@example.com'],
    )

the result is send_email_test.py works fine, which means the mail server functions as expected, but i can’t send email in the forum like ‘reset password’ and ‘send activation email’

please share some ideas to enlighten me thanks
