	{
		String host = args[0];
	    String from = args[1];
	    String to = args[2]; 
	    // Get system properties

Spamming your own thread won't get you help any sooner - just the opposite I would wager. Also, "plz" is not a word. Read the forum rules regarding use of proper English. This is not a chat room.

and your posts just show you haven't got a clue as to what you're doing. That's not indicative of someone who actually does some research beyond copying code samples and hoping they will do what he wants.

Here is what I use:

public final class Mail {
	
	public static final void sendMessage(String mailAddress, String text,
			String subject) throws Exception
	{

	 Properties myProperties=new Properties();
           
        myProperties.put("mail.smtp.host", someHost);
        myProperties.put("mail.smtp.auth", "true");
        myProperties.put("mail.debug", "false");
        myProperties.put("mail.smtp.starttls.enable", "true");
       
        LmsAuthenticator ax = new LmsAuthenticator(address, pass);
		Session ses = Session.getInstance(myProperties,ax);
	
		Message msg=new MimeMessage(ses);
		
        InternetAddress fromAddress = new InternetAddress(address,yourNameForInstance);
        InternetAddress toAddress = new InternetAddress(mailAddress);
			
        msg.setFrom(fromAddress);
		msg.setRecipient(Message.RecipientType.TO,toAddress);

		msg.setSubject(subject);
		String body = text;
		msg.setContent(body, "text/plain");
			
		msg.setSentDate(new Date());
		Transport trans = ses.getTransport("smtp");
        trans.connect(host,"","");
		msg.saveChanges();
		com.sun.mail.smtp.SMTPSSLTransport.send(msg);
		trans.close();
	}
}

And the authenticator:

package ro.fortech.lms.messaging;

import javax.mail.*;

class LmsAuthenticator extends Authenticator
{  
	private String addr=null, pw=null;
	
	public LmsAuthenticator(String addr, String pw) { 
		super(); 
		this.addr = addr;
		this.pw = pw;
	}

	protected PasswordAuthentication getPasswordAuthentication() { 
		return new PasswordAuthentication(addr,pw); 
		}
	}

Well, this approach needs valid username and password of an e-mail box. However, for simple applications it's suitable.
