Java POP3 server question

[Guest]

Hi all,

I have written this code to see how the mail application response to
my pop3 commands, but it doesn't work at all.

How I want it to work is to print out the pop3 request command from
the mail application eg outlook express etc... but it doesn't seem to
print out any command at all and just does nothing... can anyone help
please.


import java.io.*;
import java.net.*;
import javax.mail.*;
import java.util.*;
import javax.mail.event.*;
import javax.mail.internet.*;

public class SimpleProxy
{
public static void main(String args[])
{
try{
ServerSocket server = new ServerSocket(8189);
Socket incoming = server.accept();
System.out.println("Waiting!");

BufferedReader reader = new BufferedReader
(new InputStreamReader(incoming.getInputStream()));

PrintWriter out = new PrintWriter
(incoming.getOutputStream(), true);

String line = reader.readLine();

System.out.println(line);




}catch(Exception ex)
{
ex.printStackTrace();
}
}


}

You could try
telnet localhost 8189
and type in the request you would expect outlook to issue.
Have you configured outlook to connect to a non-standard port?

You are listening on 8189. I hope you changed outlook's POP3 port
from 110 to 8189 ?

Be warned about something here. If you're typing, then you're fine.

But if you decide to build a bunch of data and pipe it into telnet to see
the results:

cat data | telnet <somewhere>

You can run into trouble, because telnet dies the moment that its stdin
closes. You'll need to do someting similar to this (in uxix shells):

(cat data; sleep 99999) | telnet <somewhere>
