Simple Java Mail Pop 3 client

import java.util.Properties;

import javax.mail.Flags;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Store;

public class POP3Client {

public static void main(String args[]) throws Exception {
String host = "your_mail_server_ip";

// Get system properties
Properties props = System.getProperties();

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

// Get the store
Store store;
store = session.getStore("pop3");
store.connect(host, "", "password");

// Get inbox folder

Folder folder = store.getDefaultFolder().getFolder("INBOX");;

// Get directory
Message message[] = folder.getMessages();
for (int i = 0, n = message.length; i < n; i++) {

System.out.println(i + ": Subject" + message[i].getFrom()[0] + "\t"
+ message[i].getSubject());
String content = message[i].getContent();

//This will delete the mail from the inbox after you close the folder
message[i].setFlag(Flags.Flag.DELETED, true);

// Close connection




  1. I have some problem with delete message. The message still in inbox after I run the program. Can you help me ?

  2. Hi Long,
    Did you run the same code as above? What mail server are you trying to connect to?
