目录：
准备
安装库：PyQt5，poplib，smtplib
邮件客户端主要功能包括接收邮件、发送邮件、邮件分类.........，时间有限，只做出了发送邮件和接收邮件。
接收邮件主要依赖pop服务器，发送邮件依赖smtp服务器，例如网易163邮箱的pop服务器为pop.163.com，smtp服务器为smtp.163.com，发送端口为465。
目前测试网易邮箱没有问题，但是使用前确保打开了163的 POP3/SMTP/IMAP 服务，及开启 客户端授权密码。
代码
包含三个界面，可使用QTdesigner设计GUI，也可直接使用我生成的界面py文件。三个界面如下：
ui生成的代码分别是：

运行emailServer.py后出现主界面，在进行操作前请先登录。
登录后点击刷新信箱将会显出最新的10封邮件，点击表格任意行将会在下方显示邮件详情
点击发送邮件可弹出发送邮件窗口，填写必要信息后点击发送，稍作等待会有弹窗提示发送成功或失败：
发送成功后收件人会收到邮件。
目前客户端存在一些问题：1)无法添加图片或附件。2)发送邮件成功后客户端可能会被关闭。
