Enviando emails com Java, não conecta ao SMTP

Olá pessoal, não consigo enviar email pelo java, aparentemente mesmo colocando o servidor que deve ser enviado ele assume localhost como servidor de email:

Alguem já passou por isso ?

import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.activation.*;
import javax.mail.*;

public class sendMail { public static void main(String[] args) { // Recipient's email ID needs to be mentioned.

 String to = "jose.joao@meusmtp.com";
 // Sender's email ID needs to be mentioned
 String from = "naoresponde@meusmtp.com";
 // Assuming you are sending email from localhost
 String host = "meu.smtp.com";
 // Get system properties
 Properties properties = System.getProperties();
 // Setup mail server
 properties.setProperty("meu.smtp.com", host);
 // Get the default Session object.
 Session session = Session.getDefaultInstance(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();
 }
 }
}

Desde já agradeço.
