python 发送邮件

原文：http://blog.csdn.net/marksinoberg/article/details/51506308

要发送邮件前需要做准备工作

1.启动邮箱的smtp/pop协议；开启时系统会提示给我们一个邮箱客户端的授权码，作用就是我们登陆的时候替代原来的登陆密码

如果没有启动smtp/pop协议则会提示：smtplib.SMTPAuthenticationError: (535 Error：authentication failed）

如果不是使用的授权码登录则会提示：smtplib.SMTPAuthenticationError: (550, b'User has no permission')
