Dear friends,
I have found several requests regarding the mailing from behing a firewall/proxy with Authentication.. So here is the entire code for the same..
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
import java.util.*;
import javax.mail.*;
import javax.mail.event.*;
import javax.mail.internet.*;
public class MailClient extends Frame{
static String mailHost="proxyAddress";
public MailClient() {
public static void main(String[] args) {
Properties properties=new Properties();
properties.put("mail.smtp.host",mailHost);
properties.put("mail.smtp.auth","true");
Session session=Session.getDefaultInstance(properties,new MyAuthentication());
try{
Message msg=new MimeMessage(session);
InternetAddress address[]={new InternetAddress("toAddress1.domain.com")};
msg.setRecipients(Message.RecipientType.TO,address);
msg.setSubject("Test Mail");
msg.setFrom(new InternetAddress("[email protected]"));
msg.setContent("Please reply.. This is a java mail using Authentication
technique..","text/plain");
Transport transport=session.getTransport("smtp");
transport.connect();
transport.sendMessage(msg,msg.getAllRecipients());
