import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class MailExample {
public static void main (String args[]) throws Exception {
String host = "127.0.0.1";
String from = "localhost";
String to = "[email protected]";
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
//props.put("mail.smtp.auth", "true");
// Get session
Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(from));
Address toAddress = new InternetAddress(to);
// Set the to address
message.addRecipient(Message.RecipientType.TO,
toAddress);
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
