cannot send email with javamail and zimbra server

Question

I try to send email using javamail to Zimbra server but always receive error Client host rejected: Access denied

This is my java code:

public class TestMail {
    public static void main(String[] args) throws MessagingException {
        // provide recipient's email ID
        String to = "other_email@domain.com";

        // provide sender's email ID
        String from = "admin@domain.com";
        // provide username
        final String username = "admin@domain.com";
        // provide password
        final String password = "password-here";

        // provide host address
        String host = "mail.domain.com";
        // configure SMTP server details
        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
       // setting starttls
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.port", "587");

        // create the Session object
        Session session = Session.getInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        });
        
        

        try {
            // create a MimeMessage object
            Message message = new MimeMessage(session);

            // set From email field
            message.setFrom(new InternetAddress(from));

            // set To email field
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));

            // set email subject field
            message.setSubject("Here comes Jakarta Mail!");

            // set the content of the email message
            message.setText("Just discovered that Jakarta Mail is fun and easy to use");

            // send the email message
//          Transport.send(message);
            
            Transport tr = session.getTransport("smtp");
            tr.connect(host, username, password);
            message.saveChanges();
            tr.sendMessage(message, message.getAllRecipients());
            tr.close();

            System.out.println("Email Message Sent Successfully");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        } 
    }
}

I think error because it seems java code don't send AUTH PLAIN but I don't know why, maybe I forget configure properties?

But with nodejs code then email sent success with AUTH PLAIN
