我有一个发送签名的电子邮件可爱的小Java客户端。 我们有需要的用户名/密码验证发送邮件的Exchange服务器。

当我连接到Exchange服务器，我得到这个错误： 

avax.mail.AuthenticationFailedException: failed to connect
        at javax.mail.Service.connect(Service.java:322)
        at javax.mail.Service.connect(Service.java:172)

当我连接到其他服务器（Unix服务器），我没有问题。

以下是完整的调试跟踪。 我无法弄清楚。

Answer 1:

显然，微软的Exchange SSL连接不正确的Java邮件API建立的。 它依赖于使用SSLSocketFactory为，但如果我没有记错，MS Exchange需要有点混合的方法。

无论如何，我有这段代码在我的项目之一： 

import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.*;
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class ExchangeSSLSocketFactory extends SSLSocketFactory {

private SSLSocketFactory sslSocketFactory;
private SocketFactory socketFactory;

public ExchangeSSLSocketFactory() {
    try {
        socketFactory = SocketFactory.getDefault();

        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, new TrustManager[] { new EmptyTrustManager() }, null);
        sslSocketFactory = (SSLSocketFactory)context.getSocketFactory();
    }
    catch (Exception e) {
        throw new RuntimeException(e);
    }
}

private final class EmptyTrustManager implements X509TrustManager {
    public void checkClientTrusted(X509Certificate[] cert, String authType) throws CertificateException {}

    public void checkServerTrusted(X509Certificate[] cert, String authType) throws CertificateException {}

    public X509Certificate[] getAcceptedIssuers() {
        return new java.security.cert.X509Certificate[0];
    }
}

public static SocketFactory getDefault() {
    return new ExchangeSSLSocketFactory();
}

@Override
public Socket createSocket(Socket socket, String s, int i, boolean flag) throws IOException {
    return sslSocketFactory.createSocket(socket, s, i, flag);
}

@Override
public Socket createSocket(InetAddress inaddr, int i, InetAddress inaddr1, int j) throws IOException {
    return socketFactory.createSocket(inaddr, i, inaddr1, j);
}

@Override
public Socket createSocket(InetAddress inaddr, int i) throws IOException {
    return socketFactory.createSocket(inaddr, i);
}

@Override
public Socket createSocket(String s, int i, InetAddress inaddr, int j) throws IOException {
    return socketFactory.createSocket(s, i, inaddr, j);
}

@Override
public Socket createSocket(String s, int i) throws IOException {
    return socketFactory.createSocket(s, i);
}

@Override
public Socket createSocket() throws IOException {
    return socketFactory.createSocket();
}

@Override
public String[] getDefaultCipherSuites() {
    return sslSocketFactory.getSupportedCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return sslSocketFactory.getSupportedCipherSuites();
}

}

你告诉Java邮件API通过设置以下属性来使用这个套接字工厂：

  • ssl.SocketFactory.provider
  • mail.smtp.socketFactory.class

到完整的类名称ExchangeSSLSocketFactory

从你的调试输出，似乎你已经有：

  • mail.smtp.starttls.enable设置为true

有了这一切的地方，这个问题应该得到解决。



Answer 2:

我有同样的问题。 现在它工作正常。 我禁用了防病毒（迈克菲）和纠正用户名（我不必要给域，而它不需要）。



Answer 3:

尝试禁用明确平原登录： 

properties.setProperty("mail." + protocol + ".auth.plain.disable", "true");

要么

props.put("mail.smtp.auth.plain.disable", true);

显然有在交流的一些版本在那里做广告的普通身份验证支持，事实总是会失败时的错误。
