django - ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:997)

I'm trying to send an email in django, but I can't. I keep getting an SSLError (With the code below) or I get timed out (When I use port 465)

EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'
EMAIL_HOST = 'smtp.office365.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = config['EMAIL']
EMAIL_HOST_PASSWORD = config['PASSWORD']
DEFAULT_FROM_EMAIL = config['EMAIL']
EMAIL_USE_SSL = False
EMAIL_USE_TLS = False
EMAIL_USE_STARTTLS = True

How do I fix this?

Here are the configuration issues that are causing this error:

1. Your EMAIL_BACKEND is not correctly specified.
2. You are correctly using port 587 for the EMAIL_PORT but EMAIL_USE_TLS is False.
3. You can't set both EMAIL_USE_TLS and EMAIL_USE_SSL to False.

Corrections:

1. EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"

2. If you are setting EMAIL_USE_SSL to False:

   EMAIL_USE_SSL = False
   EMAIL_USE_TLS = True
   EMAIL_PORT = 587
   

3. If you are setting EMAIL_USE_TLS to False:

   EMAIL_USE_SSL = True
   EMAIL_USE_TLS = False
   EMAIL_PORT = 465
   

For further information, you can refer to Django's documentation on email sending here.
