I am trying to send email using the javamail api and it looks like I have to install a SMTP server to get it working.I enabled the default SMTP server on IIS 6 on windows 8. I followed all the steps mentioned in the following blog for setting it up <http://pdhewaju.com.np/blog/how-to-install-smtp-on-windows-8-developer-preview/>. But still I am getting the following exceptions when I run the code sample given on JavaMail API's wiki page: 

```
javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25;
  nested exception is:
    java.net.ConnectException: Connection refused: connect

```

The code is as follows:

```
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class EmailTester
{
   public static void main(String [] args)
   {    
      // Recipient's email ID needs to be mentioned.
      String to = "mymail@gmail.com";//My email address

      // Sender's email ID needs to be mentioned
      String from = "blah@blah.com";// Should this be a real email address?

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties = System.getProperties();

      // Setup mail server
      properties.setProperty("mail.smtp.host", host);
      properties.put("mail.debug", "true");
      // Get the default Session object.
      Session session = Session.getInstance(properties);

      try{
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.
         message.addRecipient(Message.RecipientType.TO,
                                  new InternetAddress(to));

         // Set Subject: header field
         message.setSubject("This is the Subject Line!");

         // Now set the actual message
         message.setText("This is actual message");

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
      }catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}

```

So I have multiple questions:
1) Is installing SMTP server on IIS a good idea for use with JavaMail API? Am I doing things completely wrong?

2) Should I use third party SMTP server like Apache James?
