我这几天也账号在做发送邮件！呵呵 你在试验发送邮件的时候用企业邮箱！或者126的 别的不好用！

LumiSoft.Net
网络协议栈类库有完整实现，你自己去看
很有名的开源方案

哥们看错了吧?我要的是收邮件的POP的,不是stmp的~不过谢了,你这个发别的也可以吧?stmp服务器改了端口改了应该就可以吧....

这个是发送邮件的啊!?

[睡神在睡觉]

自己仍回去....高手们,给个思路吧~

[Dobzhansky]

你要全部自己写?

邮件正文跟附件是作为一个整体收到的, 你要拆分的, 比较复杂

你可以找个开源的, 把邮件消息的封装类搞出来, 用来分析邮件, 分离附件.

如何使用C#访问POP3服务器
内容:
This is a follow up to my SMTP example that shows how to
access your POP3 server. This program connects and logs on
to your POP3 server, and checks to see how many new
messages you have.

The instantiation of the POP is in Main() like this:
POP pop = new POP("pop-server", "loginname", "password");
You must replace "pop-server" with the name of your POP
server, "loginname" with your own log in, and "password"
with your password. The class has two methods. The Connect
method takes care of actually logging in to the server. The
TCPClient class is used to establish the connection.
The "user" and "pass" commands are used to login. Connect
returns a NetworkStream object created during the
connection process. The second method is
GetNumberOfNewMessages, which returns the number of unread
messages on the server. The response to the "stat" command
is parsed to extract the number of new messages.


Requirement:

Requires .NET SDK


How To Compile?


csc /r:System.Net.dll /r:System.IO.dll pop.cs

Source Code

using System.Net.Sockets;
using System.IO;
using System.Net;
using System;

class POP
{
string POPServer;
string user;
string pwd;
public POP(){}
public POP(string server, string _user, string _pwd)

}
private NetworkStream Connect()
{
TCPClient sender = new TCPClient(POPServer,110);
Byte[] outbytes;
string input;
NetworkStream ns = null;
try{
ns = sender.GetStream();
StreamReader sr = new StreamReader(ns);
Console.WriteLine(sr.ReadLine() );

input = "user " + user + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes
(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length) ;
Console.WriteLine(sr.ReadLine() );

}
}
public int GetNumberOfNewMessages()
{
Byte[] outbytes;
string input;
try{
NetworkStream ns = Connect();
StreamReader sr = new StreamReader(ns);

input = "stat" + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes
(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length);
string resp = sr.ReadLine();
Console.WriteLine(resp);
string[] tokens = resp.Split(new Char[] {' '});

input = "quit" + "\r\n";
outbytes = System.Text.Encoding.ASCII.GetBytes
(input.ToCharArray());
ns.Write(outbytes,0,outbytes.Length);
Console.WriteLine(sr.ReadLine());

sr.Close();
ns.Close();
return tokens[1].ToInt32();
}
catch(InvalidOperationException ioe){
Console.WriteLine("Could not connect to mail server");
return 0;
}
}
public static void Main()
{
POP pop = new POP("pop-server", "loginname", "password");
Console.WriteLine("New Messages = {0}",

===========================
我做了一个pop3接收客户端，在收取邮件时，服务器返回得内容如下：

+OK Return-Path: <[e-mail]>Delivered-To: [e-mail]: (qmail 32409 invoked from network); 28 Nov 2002 01:31:31 -0000Received: from unknown (HELO 21cn.com) (61.140.60.248) by 202.106.187.186 with SMTP; 28 Nov 2002 01:31:31 -0000Received: from 21cn.com([127.0.0.1]) by 21cn.com(AIMC 2.9.5.6) with SMTP id jm93de57653; Thr, 28 Nov 2002 09:48:55 +0800Received: from 21cn.com([10.2.2.1]) by 21cn.com(AIMC 2.9.5.1) with SMTP id jm73de5e038; Thr, 28 Nov 2002 09:48:55 +0800Content-Type: text/plainContent-Transfer-Encoding: 8bitMIME-Version: 1.0Message-ID: <[e-mail]>X-AIMailer: AIMC 2.9.5.6 2002.10.10X-AIMime: MIME/SMIME Lib 2.9 2.9 2002.10.10Date: Thu, 28 Nov 2002 09:34:33 +0800 (CST)From: "??????"<[e-mail]>To: yysscheng <[e-mail]>Cc: Subject: =?gb2312?b?sOy5q9fUtq+7rw==?=X-Priority: 3X-Originating-IP: 61.163.14.2X-AIMC-AUTH: (null)X-AIMC-MAILFROM: [e-mail]?????? ?????????????????????????? ?????????? ?????? 11.28----------------------------------------------?????????????????????????????????? http://y.21cn.com ????A??210099???????????????????? http://sms.21cn.com/baobei/sjsy.html 21CN??????3??????12??10?????????? http://mail.21cn.com/huodong/9yue/ 21CN????????????????????????U?? http://mail.21cn.com/huodong/11yue/business/

其中的汉字如何解析出来？
（注：我得连接类如下：
public class Pop3Connection
{
private TcpClient socket;
private StreamReader reader;
private StreamWriter writer;
private bool connected;
public bool Connected
{
get{return connected;}
}
public Pop3Connection()
{
// TODO: 在此处添加构造函数逻辑
connected=false;
socket=new TcpClient();
}
~Pop3Connection()
{
socket=null;
}
internal void Open(string host,int port)
{
if(host==null || host.Trim()=="")
{
throw new ArgumentException("Host is null!");
}
if(port<0)
{
throw new ArgumentException("Port is invalid!");
}
try
{

socket.Connect(host,port);
reader=new StreamReader(socket.GetStream(),System.Text.Encoding.ASCII );
writer=new StreamWriter(socket.GetStream(),System.Text.Encoding.ASCII);
connected=true;
}
catch(Exception e)
{
connected=false;
}
}
internal void SendCommand(string cmd)
{
writer.WriteLine(cmd);
writer.Flush();
}
internal void GetReply(out string reply )
{
if(Connected)
{reply=reader.ReadLine();}
else
{reply="";}
}
internal void Close()
{
reader.Close();
writer.Flush();
writer.Close();
reader=null;
writer=null;
socket.Close();
connected=false;
}
}

多谢各位.用EMail.dll做好了,发命令也做了个,但是有现成的dll何必非要自己写啊...呵呵,散分~
