JAVA方面的，求个源程序！谢谢了。

[powerchuangwai]

就只有37分了，呵呵。


求 用socket,seversocket实现的SMTP、POP3邮件服务器的源程序。



谢谢大家了。后面再加分。

[zcp1985]

为了加分而来 确实没做过这类的

[powerchuangwai]

这个问题难吗？

[yktd26]

你这是要实现一个邮件服务器还是实现与一个邮件服务器通话，来发送或者接受邮件？
而且建议这种问题可能google比csdn好，你要的是个整个一个项目的源码，这里恐怕没有google好用，
或者可以去csdn下载频道找找看

[mengxuejinaitianfang]

大定来项啊

[powerchuangwai]

这个问题 真的好难吗:?

[njfengxue]

帮你顶一下!虽然不会，o(∩_∩)o...哈哈

[wubo1234]

这个很难吗？自己作曲

[shijieyounihao]

以前印象中好像也有人问过。

[powerchuangwai]

又加了10分。。

大家多讨论呀。

[renjianguokeivor]

刚开始学，帮顶

[powerchuangwai]

怎么还没有可以采纳的答案呀。再加10分。

ServerSocketConnectionDemo是服务器端
ClientSocketConnectionDemo是客户端

[powerchuangwai]

肯请有人指点迷津。。。

[wisereach]

网上有很多。自己搜吧

[powerchuangwai]

呵呵，谢谢了，问一下，基于socket通信，可以实现B/S模式的应用吗？

也就是说在B/S模式下，可以使用socket通信吗？
