使用python自动发送邮件

最近研究邮件透明加密技术，，需要使用脚本自动发送邮件测试，于是使用python写了一个小程序。程序可以自动选择不定数量的附件，随机选择主题，随机选择正文，然后自由组合发送，非常适合邮件方面的测试任务。顺便说一下邮件透明加密技术和市场上的其他邮件加密技术相比再部署上非常简单。”透明“二字就是部署不改变用户原有习惯，目前的产品有天御云安的隐密邮，网址是https://mail.tyyunan.com/， 各位感兴趣的可以看一下。

Appium+python 自动发送邮件(1)

SMTP:简单传输协议,实在Internet上传输Email的事实标准. Python的smtplib模块提供了一种很方便的途径来发送电子邮件,它对SMTP协议进行了简单的封装. python中发送邮件除了SMTP模块外,还需用到email模块.email模块主要用来定义邮件的标题.正文.附件. 一.SMTP的方法 1.SMTP模块的方法 connect(host,port) host:指定连接的邮箱服务器 port:指定连接服务器的端口号 login(user,passwork) user:登

Python 自动发送邮件

简单邮件传输协议(SMTP)是一种协议,用于在邮件服务器之间发送电子邮件和路由电子邮件.Python提供smtplib模块,该模块定义了一个SMTP客户端会话对象,可用于使用SMTP或ESMTP侦听器守护程序向任何互联网机器发送邮件. SMTP通讯的基本流程可以概括为以下几点: 1.连接SMTP服务器 2.登陆用户名和密码 3.发送指定邮件内容 4.退出SMTP连接 一.发送纯文本格式邮件 1 #coding:utf-8 2 import sys 3 reload(sys) 4 sys.setd
