邮件客户端源码
Ⅰ 邮件发送程序客户端(C语言源代码)
SMTP协议是用于发送电子邮件的主要通信协议，是C语言进行网络编程时经常都会使用到的基础协议之一。邮件发送客户端程序要求使用C语言socket通信来完成SMTP协议，实现邮件发送程序的客户端应用，通过该程序能够向远程的SMTP服务器发送电子邮件的请求，并发送到指定的电子邮箱之中。 第一阶段：只要求通过dos窗口实现简单文本邮件的发送，具体的要求如下： 程序启动后录入SMTP服务器地址； 录入SMTP服务器用户名和密码； 录入收件人地址和抄送人地址（允许录入多个，中间以分号分隔）； 录入邮件主题； 录入邮件内容完成后发送邮件； 邮件发送成功后系统提供邮件发送成功； 第二阶段：要求能够实现发送MIME格式邮件或利用Win32编程将程序升级为桌面应用程序，进入第二阶段必须满足以下条件： 必须是在充分理解SMTP协议的基础上； 必须是在充分理解MIME格式的基础上； 利用C语言将发送的内容格式化为MIME格式； 可以首先考虑只实现MIME格式的一部分格式化需求； 升级桌面应用程序必须对Win32 API有一定的理解和掌握；
Ⅱ 基于SMTP协议,设计邮件发送客户端程序源代码可执行文件 附有程序流程图 最好有设计原理

Ⅵ 电子邮件客户端JAVA源代码。
不知道你要问的是什么 是求客户端的源代码吗？ 现在只要网络 java的御和搏电子邮箱 有现成的jar包和调镇祥用方法（pop3协议） 自己就可以写棚物
linux的软件本来就是开源的，你直接下个linux邮件的软件源代码不就行了
Ⅷ 如何查看邮件的源代码/方法技巧
由于各种邮件客户端软件或Web方式的不同，造成查看的途径各有差异。
比如， Foxmail
第一步：选中邮件，鼠标右击邮件的主题，在下拉菜单中选择“原始信息(Ctrl＋I)...”，如下图：
第二步：在打开的“原始信息”窗口首先看到邮件头的信息，点击“全部”可看完整源码。
其他的，你可以网络一下。
