jmail用pro版,free版不支持pop

谢谢zhanqiangz(闲云野鹤) ，不好意思，是我没有说明白，
我想用System.Net.Sockets在Winform下VB.NET来实现。

#5

买本Wrox出的《.NET网络高级编程》来看看就明白了

最近正好封装了一个POP3类，拿出来献丑了，呵呵，是基于socket的。
注：接收到的邮件如果含附件，需要自己写代码来解码（邮件是MIME编码，也就是BASE64码）,我的类只负责把邮件原文从服务器上取回来，其他如去邮件标题，提取附件等需在你的程序代码中完成（其实是偶还没得及做，呵呵）。

这很容易的.
你只要弄懂SERVER的通讯就可以了.源代码如下:

假设我要收：fhlan@163.com的邮件，恕小弟笨得很，请问：
您的pop.RemoteServer = "xxx.mail.com"要怎样设呢？
pop.RemoteServer = "163.mail.com"
pop.RemoteServer = "www.163.com"
pop.RemoteServer = "POP3.163.com"
pop.RemoteServer = "http://www.163.com"
pop.RemoteServer = "fhlan@163.com"
都提示：
Additional information: 找不到这样的主机

关注该问题

To：楼主
fhlan@163.com邮件的话，要看它的POP3服务器的地址是什么，然后填上就行。但服务器地址是由服务商提供的，不一定就是以“pop3.”开头的，要去看一下邮箱的帮助中心内容。
比如上海热线的pop3服务器是：online.sh.cn，RemoteServer属性填这个就行了。

我帮你看了一下，163的pop3服务器地址："pop.163.com"，填上这个就可以了。不过不知道163
免费邮箱支不支持POP3接收邮件。
你还可以试试其他邮箱，必须支持POP3的邮箱才能用这个类来接收邮件。
你的126的邮箱的pop3地址是:"pop3.126.com"
