Retreiving E-mails

Question

Hi, I've recently been working with Java Mail and had a bit of a problem. I can send e-mails fine, but when i used the tutorials code to retrieve my e-mails it gets stuck at the connection even though I am using the same connection information to send as i am to retrieve. If anyone has any information as to why this would be i would greatly appreciate your time and effort. It freezes at the DEBUG POP3 when it tries to connect and I am not sure why.
    public MailClient() throws IOException{
    props = new Properties();
    System.out.println("Please enter username");
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    props.put("mail.smtp.user", in.readLine());
    System.out.println("Please enter password");
    props.put("mail.smtp.password", in.readLine());
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.port", "465");
    props.put("mail.smtp.starttls.enable","true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");
    public void checkMail() throws NoSuchProviderException, MessagingException{
auth = new SMTPAuthenticator();
// Get session
session = Session.getDefaultInstance(props, auth);
session.setDebug(true);
// Get the store
Store store = session.getStore("pop3");
store.connect("smtp.gmail.com", 465, props.getProperty("mail.smtp.user"),
        props.getProperty("mail.smtp.password"));
// Get folder
Folder folder = store.getFolder("Inbox");
folder.open(Folder.READ_ONLY);
// Get directory
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
   System.out.println(i + ": " + message.getFrom()[0]
+ "\t" + message[i].getSubject());
// Close connection
folder.close(false);
store.close();
private class SMTPAuthenticator extends javax.mail.Authenticator
@Override
public PasswordAuthentication getPasswordAuthentication()
return new PasswordAuthentication(props.getProperty("mail.smtp.user"), props.getProperty("mail.smtp.password"));

First of all, read the [JavaMail FAQ|http://java.sun.com/products/javamail/FAQ.html] and see how to significantly simplify your configuration and your code.
Then, read the debugging tips in the FAQ.
Most likely your firewall is blocking your access.
