linux 系统调用python脚本发送自定义系统邮件

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import sys
import smtplib
import email.mime.multipart
import email.mime.text

server = 'smtp.163.com'
port = '25'

def sendmail(server,port,user,pwd,msg):
    smtp = smtplib.SMTP()
    smtp.connect(server,port)
    smtp.login(user, pwd)
    smtp.sendmail(msg['from'], msg['to'], msg.as_string())
    smtp.quit()
    print('邮件发送成功email has send out !')


if __name__ == '__main__':
    msg = email.mime.multipart.MIMEMultipart()
    msg['Subject'] = '你是风儿我是沙，缠缠绵绵回我家'
    msg['From'] = '1856565020@163.com'
    msg['To'] = '1829477883@qq.com'
    user = '1856565020'
    pwd = 'xxx123456'
    content='%s
%s' %('
'.join(sys.argv[1:4]),' '.join(sys.argv[4:])) #格式处理，专门针对我们的邮件格式

    txt = email.mime.text.MIMEText(content, _charset='utf-8')
    msg.attach(txt)

    sendmail(server,port,user,pwd,msg)

以上为邮件脚本其中的登陆密码为客户端授权码
