尝试使用JavaMail中的NTLM连接到Exchange服务器。我可以连接到SMTP，但不能连接到IMAP。我还可以使用相同的主机/用户名/密码通过OS

X Mail.app应用程序进行身份验证，帐户类型=“ IMAP”，端口143，ssl = false，authentication =

NTLM，域名=“。

连接代码：

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.Store;
import java.util.Properties;
    public class NTLMTest {
        public static void main(String[] args) throws Exception {
            final String host = "example.com";
            final String user = "bob";
            final String password = "password";
            final Properties properties = new Properties();
            Session session = Session.getDefaultInstance(properties);
            session.setDebug(true);
            // SMTP CONNECT
            final Transport transport = session.getTransport("smtp");
            transport.connect(host, user, password);
            System.out.println("SMTP Connect successful");
            // IMAP CONNECT
            final Store store = session.getStore("imap");
            store.connect(host, user, password);
            System.out.println("IMAP Connect Successful");
        }
    }

输出：

login用反斜杠包装用户名，出现以下错误：

Exception in thread "main" javax.mail.AuthenticationFailedException: One time use of a plaintext password will enable requested mechanism for user

SMTP连接部分中用户名周围的反斜杠导致其失败。我无法确定“一次性使用”错误是否朝着正确的方向迈出了一步。

我注意到-通过SMTP-

NTLM身份验证不适用于旧版本的javax.mail（最高1.4.1），但现在可用于版本1.4.5。并且要指定的用户名的格式为“域\用户名”。可能是同样的效果（javax.mail版本不同）也适用于IMAP。
