java.net.SocketException: Connection closed by remote host

Hi,

Iam trying to send an email from zoho to gmail , using java mail api. Am getting the error and my code is as follows.

final String username = " xxxxxx@novelirs.com";
final String password = "xxxxxxx";
Properties props = new Properties();
        props.setProperty("mail.smtp.host", "smtp.zoho.com");
        props.setProperty("mail.smtp.port", "587");
        props.setProperty("mail.smtp.starttls.enable", "true");
        props.setProperty("mail.smtp.auth", "true");

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

        try {
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(from));
            message.setRecipients(Message.RecipientType.TO,    InternetAddress.parse(to));
            message.setRecipients(Message.RecipientType.CC,    InternetAddress.parse(cc));
            message.setRecipients(Message.RecipientType.BCC,InternetAddress.parse(bcc));
            message.setSubject(subject);
            message.setContent(body, "text/html");
            Transport.send(message);
