Like myself, if your deployed django app is on heroku and using https meaning you need port 465, you should not forget to add these same values below here to your heroku Config Vars. It threw 'connection unexpectedly closed' error untill i had to add this.

# settings.py

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'apikey'
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_HOST_PASSWORD')                   
                     # replace here with the long SendGrid API secret code 
                     # xyxyxyxyzzzyz on heroku's Config Vars
EMAIL_PORT =  465 
EMAIL_USE_SSL = True

Without that, debugging on localhost or development sever will work (with port 587 under http) but not at deployment under port 465 with https
