楼主公司之前一直都有短信接口 报警都是自己写脚本通过短信方式来报警，但今天领导突然要求 收到nagios邮件报警，楼主一时激动 写个python的小程序吧，希望对大家有帮助

vim /usr/local/nagios/libexec/sendmail

def usage():
  print """sendmail is a send mail Plugins
  Usage:

  sendmail [-h|--help][-t|--to][-s|--subject][-m|--message]

  Options:
         --help|-h)
                print sendmail help.
         --to|-t)
                Sets sendmail to email.
         --subject|-s)
                 Sets the mail subject.
         --message|-m)

         ./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!"""
