   一些常用邮箱发件服务器及端口号
   邮箱   发件服务器    非SSL协议端口    SSL协议端口
   163   smtp.163.com      25             465/587
   qq    smtp.qq.com       25             465/587

   发送邮件的几个错误：
   1.550错误（smtplib.SMTPAuthenticationError: (550, b‘User has no permission‘)）
     535错误（smtplib.SMTPAuthenticationError: (535, b‘Error: authentication failed‘)）
     邮箱一般是不开启客户端授权的，所以登录是拒绝的，需要去邮箱开启，然后会发送短信
     获取授权码作为客户端登录的密码（login方法中的密码）
   2.503错误（503 ‘Error: A secure connection is requiered(such as ssl)’之类）
     例如我们使用QQ邮箱是需要SSL登录的，所以需要smtplib.SMTP()改成smtplib.SMTP_SSL()

   @from_addr  发送邮件的地址
   @to_addr    接收邮件的地址（可以是列表）
   @mail_host  邮箱的SMTP服务器地址
   @mail_pass  邮箱开启smtp 需要的授权码
