Flask 电子邮件支持 - 发送电子邮件时获取 SSLError [Errno 1]

Question

我正在尝试为 Flask 应用程序设置电子邮件服务器。我收到 SSLError。这是我第一次学习任何类型的 Web 开发。

这是我配置服务器的方式：

# mail server settings
MAIL_SERVER = 'smtp.mail.yahoo.com'
MAIL_PORT = 587
MAIL_USE_TLS = False
MAIL_USE_SSL = True
MAIL_USERNAME = 'email@yahoo.com'
MAIL_PASSWORD = 'password'


# administrator list
ADMINS = ['email@yahoo.com']

这是我的init脚本中处理邮件的部分：

app.config.from_object('config')
mail = Mail(app)

这是我尝试发送电子邮件时错误的回溯：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/Users/user/microblog/flask/lib/python2.7/site-packages/flask_mail.py", line 491, in send

    new_socket = ssl.wrap_socket(new_socket, self.keyfile, self.certfile)

    self._sslobj.do_handshake()   
ssl.SSLError: [Errno 1] _ssl.c:504: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

谢谢！

MAIL_PORT = 587
MAIL_USE_TLS = False
MAIL_USE_SSL = True

端口 587 用于显式 TLS（STARTTLS 命令），因此您可能必须使用 MAIL_USE_TLS 而不是 MAIL_USE_SSL。MAIL_USE_SSL 用于隐式 TLS，您可以在端口 465 上直接连接 TLS。
