# 第三方 SMTP 服务

sender = '1****@163.com'  # 发件人邮箱
receivers = ['1*****@163.com']  # 接收邮件，可设置为你的其他邮箱，如果是QQ邮箱，需要开启stmp
  ##############使用qq邮箱的时候，记得要去开启你的qq邮箱的smtp服务；##############
    # 方法：
    # 1）登录到你的qq邮箱；
    # 2）找到首页顶部的【设置】并点击；
    # 3）找到【账户】这个选项卡并点击，然后在页面中找到“SMTP”相关字样，找到【开启】的超链接，点击后会告诉你开启方法（需要发个短信），然后按照指示操作，最终会给你一个密码，这个密码可以用于在代码中当作邮箱密码
