title: Java mail, set reply-to address not working
body: <p>I wrote a small email sending program in java, it has <code>from</code>, <code>to</code> and <code>reply-to</code> address, when the client tries to reply to the mail, it should be able to reply to the <code>reply-to</code> address. 
  Currently it's not working, my code is below:</p>
  
  <pre><code>// File Name SendEmail.java
  
  import java.util.*;
  import javax.mail.*;
  import javax.mail.internet.*;
  import javax.activation.*;
  
  public class SendEmail
  {
     public static void main(String [] args)
     {
  
        // Recipient's email ID needs to be mentioned.
        String to = "xyz@gmail.com";
  
        // Sender's email ID needs to be mentioned
        String from = "abcd@gmail.com";
  
        // Assuming you are sending email from localhost
        String host = "localhost";
  
        // Get system properties
        Properties properties = System.getProperties();
      properties.put("mail.smtp.from", "mnop@gmail.com");
  
        // Setup mail server
        properties.setProperty("mail.smtp.host", 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("New Message goes here");
  
           // Send message
           Transport.send(message);
           System.out.println("Sent message successfully....");
        }catch (MessagingException mex) {
           mex.printStackTrace();
        }
     }
  }
