error on sending mail while test sending mail successfully in Django - django

Question

I'm coding about Forget Password feature on Django. Reset mail will be sent when user fill out form and click Reset button. But I have a trouble here, mail isn't sent after user click button. I use sendtestmail command, sending mail successfully. And more, the content and mail subject that I define is not in the email it sent when I check by sendtestmail command. It took me all yesterday to fix above error but didn't work. Can somebody help me.
settings.py

EMAIL_HOST_USER = os.getenv('EMAIL_HOST_USER', 'vuthehuy.hus#gmail.com')
EMAIL_HOST_PASSWORD = os.getenv('EMAIL_HOST_PASSWORD', 'my_password_app')
EMAIL_PORT = 587
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = os.getenv('DEFAULT_FROM_EMAIL', 'Colo Shop <no-reply#localhost>')
