vim /root/pyth.py

#!/usr/bin/env python3
Youxiang = ['wangkang@innovationai.cn','yupanlong1@163.com']              #定义多个发送人
import smtplib

from smtplib import SMTP_SSL
from email.mime.text import MIMEText
from email.header import Header

mail_host = "smtp.exmail.qq.com"
mail_user = "wangkang@innovationai.cn"
mail_pass = "Wk17908"
receivers = Youxiang
message = MIMEText(sys.argv[1], 'plain', 'utf-8')                 #调用参数，将$1为有邮件内容发送出去
subject = u'监听端口警告'
message['Subject'] = Header(subject, 'utf-8')
try:
        smtpObj = SMTP_SSL(mail_host)
        smtpObj.login(mail_user,mail_pass)
        smtpObj.sendmail(mail_user,  receivers, message.as_string())
