NET平台利用Jmail.net组件发送与接收邮件(源代码与组件下载)

JMail.net
      在ASP.net用JMail发送邮件的方法，它是用VS.net为我们提供的工具来把COM组件和.net的组件进行了转化，但在实际的应用中发现，它的内存占用很厉害。好了，Dimac为我们发布了JMail的.net版本.

一、下载

由于下载还需要填写邮件和其他信息，为了让大家更加方便下载点击这里可以直接下载：http://www.dimac.net/FreeDownloads/Freedownload.asp?Id=3F824152-C635-4953-ABFF-0CB11E310C0A

二、 SMTP发送邮件

源代码C# SMTP范例
using System;
using Dimac.JMail;

namespace JMailTest
{
  class MainClass
  {
    [STAThread]
    static void Main( string[] args )
    {
      // create JMail message
      Message message = new Message();
     
      // set sender
      message.From.Email = "[email protected]";

      // add a recipient
      message.To.Add( "[email protected]" );

      // set the subject & body
      message.Subject = "Hello, world!";
      message.BodyText = "Hello, world! My hovercraft is full of eels.";

      // add an attachment
      message.Attachments.Add( "C://me_dancing.wmv" );

      // send the message
      try
      {
        Smtp.Send( message, "mail.mydomain.com" );

        Console.WriteLine( "The message has been sent." );
      }
      catch ( Exception ex )
      {
        Console.WriteLine( "Failed to send message: {0}", ex.Message );
      }
    }
  }
}

三、POP3接收邮件范例
using System;
using Dimac.JMail;

namespace JMailTest
{
  class MainClass
  {
    [STAThread]
    static void Main( string[] args )
    {
      // connect to pop3 server
      using( Pop3 pop3 = new Pop3(  "mail.mydomain.com", 110,  "me",  "secret"      ) )
      {
        // iterate message
        foreach( Message message in pop3.Inbox )
        {
          // print interesting headers
          Console.WriteLine(  "{0}/t{1}/t{2}", message.Date, message.From, message.Subject );
        }
      }
    }
  }
}

四、利用 MailMerge实现群发邮件
using System;
using System.Data;
using System.Data.Odbc;
using Dimac.JMail;

namespace JMailTest
{
  class MainClass
  {
    [STAThread]
    static void Main( string[] args )
    {
      // create mailmerge instance
      MailMerge mm = new MailMerge();

      // setup template
      mm.Template.From = "[email protected]";
      mm.Template.To.Add( "<%# EmailAddress %>", "<%# Name %>" );
      mm.Template.Subject = "Hello <%# Name %>";
      mm.Template.BodyText = "Hello there <%#  Name %>. This is your e-mail address: <%# EmailAddress %>!";

      // set output directory              
      mm.OutputDirectory = "C://MailServer//Pickup";
            
      // open sql connection  
      using( OdbcConnection connection = new OdbcConnection( "DSN=MyDSN" ) )
      using( OdbcCommand command = new OdbcCommand( "SELECT EmailAddress, Name FROM Contacts", connection ) )
      {
        connection.Open();
        // get data reader        
        using( IDataReader reader = command.ExecuteReader() )
        {
          // set data source
          mm.DataSource = reader;

          // databind!
          MailMergeResult result = mm.DataBind( false );

          Console.WriteLine( "Success: {0}, Failure: {1}", result.SuccessCount, result.FailureCount );
        }
      }
    }
  }
}

五、总结

      Jmail.net完全基于.net框架开发的，应该会与asp.net更加紧密的结合在一起。更重要是JMailServer也同时发布了，这样一来可以自己架设邮件服务器了。可惜还不能下载。有兴趣的可以在dimac的网站上找找看。
