Python 利用邮件系统完成远程控制电脑的实现（关机、重启等）
0.我们如何通过邮件系统完成远程控制电脑（关机、重启等）？
实现思路：
需要有两个邮箱：接收指令邮箱（A）发送指令邮箱（B）
被控制的电脑（查看A邮箱）：
1. 每隔指定时间监听A 邮箱 查看最近的邮件
2.打开最近邮件，看是否是 B邮箱地址发来的执行命令
3.向A和B邮箱都发送主题为：反馈内容为：“目标计算机已收到指令！开始执行：xxx指令！”邮件
4. 执行指定邮箱发送的执行命令
远程人员操作：
登录B邮箱，向A邮箱发送主题为：“目标计算机执行”内容为：xxx指令（例如：关机）

2.解释说明
A邮箱：是163邮箱，需要开启smtp、pop3服务
上面所说的smtp、pop3密码，指的是开启上图所示的服务要设定的密码！！！
B邮箱：是QQ邮箱，只是用来发送执行命令到A邮箱的，所以不必开启smtp、pop2服务
3.运行截图
B邮箱向A邮箱发送命令
