PyQt5+poplib+smtplib+python3.6邮件客户端Demo

December 27, 2019 • 阅读: 1781 • 笔记&折腾



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：
