This project is unsupported.

棄坑吧,settings.py中更換郵件引擎.

?

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL='753743312@qq.com'
SQLALCHEMY_TRACK_MODIFICATIONS= False
EMAIL_HOST ='smtp.qq.com'
EMAIL_SUPPRESS_SEND= False??? # 發送郵件，為True則不發送
EMAIL_PORT = 587#SSL協議端口號
EMAIL_USE_SSL= False?????????? # 重要，qq郵箱需要使用SSL
EMAIL_USE_TLS= True????????? # 不需要使用TLS
EMAIL_HOST_USER= 'xxxxxxxxxx@qq.com'
EMAIL_HOST_PASSWORD ='xxxxxxxxxxxx'#授權碼,不是密碼
SECURITY_EMAIL_SENDER= 'no-reply@localhost'
