flask 郵件發不出去，怎麼解決？

email.py:

def send_async_email(app, msg):

with app.app_context():
mail.send(msg)


def send_email(to, subject, template, **kwargs):

app = current_app._get_current_object()
msg = Message(str(app.config["FLASKY_MAIL_SUBJECT_PREFIX"]) + str(" ") + str(subject),
sender=app.config["FLASKY_MAIL_SENDER"], recipients=[to])
msg.body = render_template(template + ".txt", **kwargs)
msg.html = render_template(template + ".html", **kwargs)
thr = Thread(target=send_async_email, args=[app, msg])
thr.start()
return thr


config.py:

class Config:

SECRET_KEY = os.environ.get("SECRET_KEY") or "hard to guess string"
MAIL_SERVER = "smtp.163.com"
MAIL_PORT = 25
MAIL_USE_TLS = True
MAIL_USERNAME = os.environ.get("MAIL_USERNAME")
MAIL_PASSWORD = os.environ.get("MAIL_PASSWORD")
FLASKY_MAIL_SUBJECT_PREFIX = ["Flasky"]
FLASKY_MAIL_SENDER = "Flasky &"
FLASKY_ADMIN = "xxx@163.com"
SSL_DISABLE = False


錯誤顯示為：

不知道問題出在哪裡，求大神指點一二，python3.4，win7

--------------------------------------------------------------------

埠的問題已經修改，也已開啟SMTP，使用的是授權密碼，依然出現同樣的錯誤，求指教

你的配置有錯誤：

MAIL_PORT = 25
MAIL_USE_TLS = True


1. 首先在163的網頁裡面，把stmp的功能打開，否則肯定不能發的

2. 用客戶端授權碼代替用戶密碼，這個也要在163設置的

3. 如果使用非SSL協議，則埠號是 25

MAIL_PORT = 25
MAIL_USE_TLS = False
MAIL_USE_SSL = False


如果使用SSL協議，則埠號是 465 或者 994

MAIL_PORT = 465
MAIL_USE_TLS = False
MAIL_USE_SSL = True


你的其他配置沒有問題，多試驗吧，肯定能發的。首先試驗用同步方式發送，再試驗非同步方式。

目測這裡出錯：


FLASKY_MAIL_SENDER = "Flasky &"


應該把等號右邊換成你自己具體的郵箱。
