mail.smtp.auth.ntlm.domain

我尝试用本地网络中的java发送电子邮件，使用微软交换服务器

 

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 =[e-mail]; 
     final String password =password; 
 
    //属性
    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）; 
 
 
    //会话
    session = Session.getInstance（道具，新的MyAuthenticator（用户名，密码））; 
 
     try {
 
         Message message = new MimeMessage（session）; 
         message.setFrom（new InternetAddress（[e-mail]））; 
         message.setRecipients（Message.RecipientType.TO，
         InternetAddress.parse（recipent_adresse））; 
         message.setSubject（Testing Subject）; 
         message.setText（Dear Mail Crawler， +\\\\\\我的电子邮件中没有垃圾邮件！）; 
 
         Transport.send（message）; 
 
         System.out.println（Done）; 
 
        } catch（MessagingException e）{
             throw new RuntimeException（e）; 
        } 
    } 
} 
  

 

这是我的验证类：
 

 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（）
     {
        返回新的PasswordAuthentication（user，pw）; 
    } 
 
} 
  

 

我使用NTLM机制，但我得到这个错误：

解决方案

我通过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。

 

我进行了以下更改：
 

1）用户名应该是Windows登录，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应该是您的Windows域 - 即如果您正常登录，则是斜杠之前的部分使用MYDOMAIN\id12345作为用户名在Windows机器上。
 

以下更新的代码：

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("[e-mail]"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[e-mail]"));
        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);
    }
  }
}

 

最后一点，您可能需要禁用/更改防病毒设置才能允许访问25端口。
