用JMAIL发送方便
[解决办法]
System.Net.Mail
MailMessage类 与 SmtpClient类
[解决办法]
下面的代码示例演示如何以异步方式发送电子邮件。

using System;
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
using System.Threading;
using System.ComponentModel;
namespace Examples.SmptExamples.Async
{
public class SimpleAsynchronousExample
{
static bool mailSent = false;
public static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e)
{
// Get the unique identifier for this asynchronous operation.
String token = (string) e.UserState;

if (e.Cancelled)
{
Console.WriteLine( "[{0}] Send canceled. ", token);
}
if (e.Error != null)
{
Console.WriteLine( "[{0}] {1} ", token, e.Error.ToString());
} else
{
Console.WriteLine( "Message sent. ");
}
mailSent = true;
}
public static void Main(string[] args)
{
// Command line argument must the the SMTP host.
SmtpClient client = new SmtpClient(args[0]);
// Specify the e-mail sender.
// Create a mailing address that includes a UTF8 character
// in the display name.
MailAddress from = new MailAddress( "jane@contoso.com ",
"Jane " + (char)0xD8+ " Clayton ",
System.Text.Encoding.UTF8);
// Set destinations for the e-mail message.
MailAddress to = new MailAddress( "ben@contoso.com ");
// Specify the message content.
MailMessage message = new MailMessage(from, to);
message.Body = "This is a test e-mail message sent by an application. ";
// Include some non-ASCII characters in body and subject.
string someArrows = new string(new char[] { '\u2190 ', '\u2191 ', '\u2192 ', '\u2193 '});
message.Body += Environment.NewLine + someArrows;
message.BodyEncoding = System.Text.Encoding.UTF8;
message.Subject = "test message 1 " + someArrows;
message.SubjectEncoding = System.Text.Encoding.UTF8;
// Set the method that is called back when the send operation ends.
client.SendCompleted += new
SendCompletedEventHandler(SendCompletedCallback);
// The userState can be any object that allows your callback
// method to identify this send operation.
// For this example, the userToken is a string constant.
string userState = "test message1 ";
client.SendAsync(message, userState);
Console.WriteLine( "Sending message... press c to cancel mail. Press any other key to exit. ");
string answer = Console.ReadLine();

// If the user canceled the send, and mail hasn 't been sent yet,
// then cancel the pending operation.
if (answer.StartsWith( "c ") && mailSent == false)
{
client.SendAsyncCancel();
}
// Clean up.
message.Dispose();
Console.WriteLine( "Goodbye. ");
}
}
}

经过测试没问题可以多发！

1.安装jmail4.3

2.找到jmail.dll（Program Files\Dimac\w3JMail4下）

3.执行Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin\ildasm.exe（可使用Visual Studio .Net 2003 命令提示),

格式如下：tlbimp c:\Program Files\Dimac\w3JMail4\jmail.dll /out:myJmail.dll /namespace:myJmail

就是我在Visual Studio .Net 2005命令提示下编译执行 tlbimp c:\Program Files\Dimac\w3JMail4\jmail.dll /out:myJmail.dll /namespace:myJmail
