Javamail在公​​司使用outlook

Question

我第一次使用 javamail，遇到了一些我不明白的异常，我在这里也看到了其他问题中的一些错误，但它们的答案对我没有帮助。这是我的代码。

        final String username = "imsan1@cdcpk.com";
        final String password = "**********";
        Properties props = System.getProperties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.host", "10.1.136.26");
        props.put("mail.smtp.port", "25");
        props.put( "mail.smtp.user" , username );
        props.put( "mail.smtp.password" , password );

        Session session = Session.getInstance(props,
          new SmtpAuthenticator(username, password)
          );


        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("imsan1@cdcpk.com"));
            message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("immni1@cdcpk.com"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"
                + "\n\n No spam to my email, please!");

            Transport.send(message);

            System.out.println("Done");

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

SMTP验证器

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;


class SmtpAuthenticator extends Authenticator {
     String user;
     String pw;
     public SmtpAuthenticator (String username, String password)
     {
        super();
        this.user = username;
        this.pw = password;
     }
    public PasswordAuthentication getPasswordAuthentication()
    {
       return new PasswordAuthentication(user, pw);
    }
}

错误日志是

非常感谢任何帮助

该代码工作正常，它给出错误的原因是因为我没有获得 SMTP 服务器的权限，因此显示异常，在配置访问权限后，邮件已发送。
