Question

我正在尝试为Flask应用设置电子邮件服务器。我得到了SSLError。这是我第一次学习任何类型的Web开发。

以下是我配置服务器的方法：

# 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']

以下是处理邮件的 init 脚本的一部分：

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

以下是我尝试发送电子邮件时的错误回溯：

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！

Answer 1

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上直接与TLS连接。
