javax.mail.AuthenticationFailedException：535 5.7.3身份验证失败

Question

我正在使用SMTP错误发送电子邮件。我无法获得身份验证。用户名和密码正确。难道我做错了什么。

错误日志是

public class EmailSender{

    public static void main(String args[]) {
        String to = "ssss@xxx.om";            // sender email
        String from = "dddd@xxx.com";       // receiver email
        String host = "dkdkdd.xxx.com";                   // mail server host

        String login="dkkdkd";

       // properties.setProperty("mail.smtp.auth", "true"); 

        Session session = Session.getDefaultInstance(properties); // default session

        try {
            MimeMessage message = new MimeMessage(session);        // email message
            message.setFrom(new InternetAddress(from));                    // setting header fields
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            message.setSubject("Test Mail from Java Program"); // subject line

            // actual mail body
            message.setText("You can send mail from Java program by using");

            // Send message
            Transport transport = session.getTransport("smtp");
            transport.connect(host, login, pass);
            Transport.send(message);
            System.out.println("Email Sent successfully....");
        } catch (MessagingException mex) {
            mex.printStackTrace();
        }
    }

}

有同样的问题。这是您收到的MS Exchange错误。您可能不被允许使用您的电子邮件通过中继发送电子邮件。Exchange服务器的管理员需要授予这样做的权限。

它与Java方面的配置问题无关。

看起来问题在于你如何进行会话部分......

尝试这样做：

private Properties emailPorperties;

……

    emailPorperties = new Properties();
    emailPorperties.put("mail.smtp.host", "your host");
    emailPorperties.put("mail.smtp.socketFactory.port", "your port");
    emailPorperties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    emailPorperties.put("mail.smtp.auth", "true");
    emailPorperties.put("mail.smtp.port", "your port");
    emailPorperties.put("mail.smtp.ssl.enable", "true");
    emailSession = Session.getInstance(emailPorperties, new Authenticator() {

            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                System.out.println("Authenticating");
                return new PasswordAuthentication(USER_NAME, PASSWORD);
            }

        });
