问题 When I try send through ./manage.py shell it takes several minutes to send a single email. When I try to send a user verification email after a form submission in a browser the browser times out with a 504, but the email is eventually sent. What could be going on? settings.py ... EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'myemail@gmail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = EMAIL_HOST_USER EMAIL_HOST_PASSWORD = os.environ.get('PASSWORD') ... views.py class
