Send mail from local machine mail server to gmail or other mail server in java

Question

I have following code

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 = "*****@gmail.com";

      // Sender's email ID needs to be mentioned
      String from = "test1@localhost";

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties = System.getProperties();

      // 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("This is actual message");

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
      }catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}

I have setup Mercury Mail Server on my local machine, Now I'm trying to send mail from local machine mail server to gmail user. I got Sent message successfully.... output. when I executed above code. But, I didn't received any mail in gmail account.

Verify that your mail server is receiving the mail from your application. You might need to enable logging on your server to do this. If the mail is not being received you need to look at the way your application is set up to deliver to it. If it is being received the problem is with your mail server config or routing and is off-topic for [so] — , Apr 06 '14 at 06:38
change this code: "addRecipient" to "setRecipients" and test. — Diego Alves, Apr 06 '14 at 06:40
Change all line code for: message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); — Diego Alves, Apr 06 '14 at 06:41
@MikeW Thanks for your reply. I have just added `Server Log`. Please verify, everything is fine ? — Ravi, Apr 06 '14 at 06:41
Looking at your log file it seems that your code is working and delivering mail to your mail server. The problem appears to be related to some routing issue in your mail server or spam filters at GMail, both of which are off-topic for [so]. — , Apr 06 '14 at 07:26

jWeaver, I went through a similar problem and solved in a way that does not know very well explain why, but work.

Change your properties mode to according with this:

    Properties props = System.getProperties();
    props.put("mail.smtp.host", host);
    props.put("mail.smtp.user", from);
    props.put("mail.debug", "true");

I have included your code,It seems fine I didn't get any error. But, still mail not received. :( – Ravi Apr 06 '14 at 06:51
Man, I recommend that you install another mail server on your machine, do the test. There may be a problem. Check the doors, if they are open. Configure it in your code: "props.put("mail.smtp.port", "465");" I use the 465 port, but you use the port that you want. Check your firewall. – Diego Alves Apr 06 '14 at 07:32
