Why can't I send an email to an hotmail account?

Question

Hey I made a simple program to send email from localhost (with a local smtp server) to other email accounts. I tried to send it to my sapo.pt email account (a Portuguese company) and it worked. But then I tried to send it to my hotmail account and it didn't worked...
Here's the code:
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class Main
    public static void main (String[] args)
        try
            postMail ();
        catch (MessagingException e)
            System.out.println ("Erro: " + e);
    public static void postMail () throws MessagingException
        final boolean debug = false;
        Properties p = new Properties ();
        p.put ("mail.smtp.host", "localhost");
        p.put("mail.smtp.port", "2525");
        Session session = Session.getDefaultInstance (p, null);
        session.setDebug (debug);
        Message msg = new MimeMessage (session);
        InternetAddress addressFrom = new InternetAddress ("[email protected]");
        Address to = new InternetAddress ();
        msg.setFrom (addressFrom);
     msg.setSubject ("test Message");
        StringBuffer mensagem = new StringBuffer ();
        String message;
     String linha;
        try
            mensagem.append ("Hi everyone this is a test message");
            message = mensagem.toString ();
            msg.setContent (message, "text/html");
            to = new InternetAddress ("[email protected]");
            msg.setRecipient (Message.RecipientType.TO, to);
            Transport.send (msg);
            Thread.sleep (10);
        catch (Exception e)
            System.out.println (e);

Sorry I forgot to mention.
When I try to email to the hotmail account I get this error:
com.sun.mail.smtp.SMTPSendFailedException: 550 Invalid recipient: [email protected]
The local SMTP server gets one sending error and I don't receive the email in my account.
Hope this helps
