Hi there,


i have been given a project in socket programming. Task is to download all the mails from remote server to localserver.

i am going through java mail tutorials. i am new to software development.

please help me in this. please let me know any books i can refer to.
please tell me how to go about.

the first example in java mail tutorial gives error: smtp host not found.

by this example can i send messages from any rediff server to any other server.

my code is like this:

import java.util.Properties;

import javax.mail.*;

import javax.mail.internet.*;

public class MailExample {
public static void main (String args[]) throws Exception
{

String host = args[0];

String from = args[1];

String to = args[2];

// Get system properties



Properties props = System.getProperties();

// Setup mail server



props.put("smtp.id.eth.net", host );

// Get session



Session session = Session.getDefaultInstance(props, null);

// Define message



MimeMessage message = new MimeMessage(session);

// Set the from address



message.setFrom(new InternetAddress("info@e-datsource.com"));

// Set the to address



message.addRecipient(Message.RecipientType.TO,
new InternetAddress("pushpa97@rediffmail.com"));


// Set the subject



message.setSubject("Hello JavaMail");


// Set the content



message.setText("Welcome to JavaMail");


// Send message


Transport.send(message);


}

}

i have compiled it.

i am giving following command to run.
java MailExample smtp.id.eth.net info@e-datsource.com pushpa97@rediffmail.com

it is giving following error.

Exception in thread "main" javax.mail.SendFailedException: Sending Failed
nested exception is:
javax.mail.MessageException: Unknown SMTP host: SMTP.id.eth.net
