如何为Microsoft Exchange配置JavaMail？

Question

I am trying to connect to a Microsoft Exchange (2010) mail account using JavaMail 1.5.1. When I try to connect, I get the following exception.

Exception in thread "main" com.sun.mail.util.MailConnectException:
    Couldn't connect to host, port: domain server, 25; timeout -1;
      nested exception is:
        java.net.SocketException: Permission denied: connect 

Here is the code I am using.

public class SendMail 
{
    public void mail () throws MessagingException
    {
        Properties props = System.getProperties();
        String protocol = "smtp";

        // Setup mail server
        props.put("mail." + protocol + ".host", "domain server");
        props.put("mail." + protocol + ".auth", "true");
        props.put("mail." + protocol + ".port", "25");

        Session session = Session.getInstance(props);
        Transport t = session.getTransport(protocol);

        try{
            t.connect("domain\\user name", "password");

        }
        finally{
            t.close();
        }
    }
}

What I am doing wrong?

Replace domain server with the actual server name in exception and code.

默认情况下 ，Exchange服务器上未启动SMTP，因此我建议您仅使用Exchange本身
