sending mail with JavaMail

[Farakh khan]

Please correct me where I am wrong?

public class sendEmail {
        public static void send(String from, String to,
                                String subject, String content)
                throws AddressException, MessagingException {
 
	Properties props=new Properties();
	Session   session  =  Session.getDefaultInstance(props,null);
 
	String protocol = "smtp";
    	props.put("mail." + protocol + ".auth", "true");
 
	Transport transport = session.getTransport(protocol);
        transport.connect("[e-mail]", "setup");        

	Message msg =new MimeMessage(session);
	msg.setFrom(new InternetAddress(from));
 
      	msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to,false));
 
           msg.setSubject(subject);
 
           msg.setContent(content,"text/html");        
 
           transport.send(msg);            
 
        }
}

Thanks & best regards

What is happening? What do you expect to happen/what is going wrong? Is there any error message? Can you post it if there is?

I was using the following code on my previous server and that was working very well

import java.io.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;   
import javax.mail.event.*;      
import java.net.*;
import javax.activation.*;


public class sendEmail {
        public static void send(String from, String to,
                                String subject, String content)
                throws AddressException, MessagingException {

	Properties props=new Properties();

        props.put("smtp.domainName.com","hostname");

	Session   session1  =  Session.getDefaultInstance(props,null);

	Message msg =new MimeMessage(session1);
	msg.setFrom(new InternetAddress(from));

      	msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to,false));

           msg.setSubject(subject);

           msg.setContent(content,"text/html");      

           Transport.send(msg);  
        }
}

Now on the new server it displays following error:
*javax.mail.SendFailedException: Invalid Addresses;*
*nested exception is:*
* com.sun.mail.smtp.SMTPAddressFailedException: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)*

I edited my /var/qmail/control/rcpthosts and inserted my whole domain names but still I am receiving the same error. My network company replied me that previous server was using the open relay but now we have to change the code to send the emails by giving username/pass then I got help with the JavaMail FAQs and written the code above but not working with same error

How can I resolve the issue?

Thanks and best regards

I updated my code by searching some articles but throwing the following error:
non-static variable this cannot be referenced from a static context
Authenticator auth = new SMTPAuthenticator();

import java.io.*;

import javax.mail.internet.*;   
import javax.mail.event.*;      
import java.net.*;

import javax.mail.PasswordAuthentication;
import java.util.Properties;
 
 
public class sendEmail {
	
	private static final String SMTP_HOST_NAME = "mail.domain.com";
    	private static final String SMTP_AUTH_USER = "[e-mail]";
    	private static final String SMTP_AUTH_PWD  = "domain";
 
 
        public static void send(String from, String to,
                                String subject, String content)
                throws AddressException, MessagingException {
 
	Properties props = new Properties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.host", SMTP_HOST_NAME);
        props.put("mail.smtp.auth", "true");
 
        Authenticator auth = new SMTPAuthenticator();
        Session mailSession = Session.getDefaultInstance(props, auth);
 
        Transport transport = mailSession.getTransport();
 
        MimeMessage message = new MimeMessage(mailSession);
        message.setContent(content, "text/html");
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
 
        transport.connect();
        transport.sendMessage(message,
        message.getRecipients(Message.RecipientType.TO));
        transport.close();
 
        }
 
	private class SMTPAuthenticator extends javax.mail.Authenticator {
        public PasswordAuthentication getPasswordAuthentication() {
           String username = SMTP_AUTH_USER;
           String password = SMTP_AUTH_PWD;
           return new PasswordAuthentication(username, password);
        }
    }
 
}
