无法使用javamail和zimbra服务器发送电子邮件

如何解决无法使用javamail和zimbra服务器发送电子邮件

我尝试使用javamail向Zimbra服务器发送电子邮件，但始终收到错误客户端主机被拒绝：访问被拒绝

这是我的Java代码：

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);
        } 
    }
}

我认为这是错误的，因为似乎Java代码没有发送 AUTH PLAIN ，但是我不知道为什么，也许我忘记了配置属性？

但是使用nodejs代码，然后电子邮件成功发送 AUTH PLAIN
