JAVAMAIL:AUTH NTLM失败了

Question

我尝试使用microsoft Exchange服务器在本地网络中发送带有java的电子邮件

有我的代码:

import java.io.UnsupportedEncodingException;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class Main {


        public static void main(String[] args) {

            final String username = "username@MyDomain.com";
            final String password = "password";

            Properties props = new Properties();
            props.put("mail.smtp.auth", "true");
            props.put("mail.debug", "true");
            props.put("mail.smtp.host", "exchange_host.MyDomain.com");
            props.put("mail.smtp.port", "25");
            props.put("mail.smtp.auth.mechanisms","NTLM");
            props.put("mail.smtp.auth.ntlm.domain","MyDomain");


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

            try {

                Message message = new MimeMessage(session);
                message.setFrom(new InternetAddress("from_adress@MyDomain.com"));
                message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse("recipent_adresse"));
                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);
            }
        }
    }

这是我的authentificator类:

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

public class MyAuthenticator extends Authenticator {

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

}

我使用NTLM机制,但我收到此错误:

请帮助我,我过去几天搜索解决方案,但我一无所获

Answer 1

我有这个工作通过NTLM连接到我们的Exchange 2010服务器.

NTLM使用您的Windows登录名和密码进行身份验证,而不是您的电子邮件地址和密码.

我做了以下更改:

1)用户名应该是Windows登录名,而不是电子邮件地址.NTLM使用您的Windows凭据进行身份验证.

2)mail.smtp.auth.ntlm.domain应该是你的Windows域 - 即斜杠前面的部分,如果你通常以"MYDOMAIN\id12345"作为用户名登录你的Windows机器.

更新的代码如下:

public class Main {
  public static void main(String[] args) {

    // *** CHANGED ***
    final String username = "id12345"; // ID you log into Windows with
    final String password = "MyWindowsPassword";

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.debug", "true");

    props.put("mail.smtp.host", "exchangeserver.mydomain.com");
    props.put("mail.smtp.port", "25");
    props.put("mail.smtp.auth.mechanisms","NTLM");

    // *** CHANGED ***
    props.put("mail.smtp.auth.ntlm.domain","WINDOMAIN"); // Domain you log into Windows with


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

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("john.smith@mydomain.com"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("the.recipient@mydomain.com"));
        message.setSubject("Test email");
        message.setText("TEST EMAIL");

        Transport.send(message);

        System.out.println("Done");

    } catch (MessagingException e) {
        e.printStackTrace();
    }
  }


  public static class MyAuthenticator extends Authenticator {

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

对于它的价值,你的原始帖子帮助我解决了我连接已经持续了好几天的问题.

最后一点,您可能需要禁用/更改防病毒设置以允许在端口25上进行访问.
