## httpd? ?如果是1则监控，为0不监控
to_mon_httpd=0
## php 如果是1则监控，为0不监控
to_mon_php_socket=0
## http_code_502??需要定义访问日志的路径
to_mon_502=0

def main():
    to=sys.argv[1]
    subject=sys.argv[2]
    content=sys.argv[3]
##定义QQ邮箱的账号和密码，你需要修改成你自己的账号和密码（请不要把真实的用户名和密码放到网上公开
，否则你会死的很惨）
    sendqqmail(‘15*******68@163.com‘,‘wan*******27‘,‘15*******868@163.com‘,to,subject,content)
if __name__ == "__main__":
    main()

#####脚本使用说明######
#1. 首先定义好脚本中的邮箱账号和密码
#2. 脚本执行命令为：python mail.py 目标邮箱 "邮件主题" "邮件内容"
