Why JavaMail connection timeout is too long

Question

In my application I connect to server to authenticate users. This is code:

try {
        Properties prop = new Properties();
        prop.put("mail.smtp.starttls.enable","true");
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.connectiontimeout", 1000);


        Session session = Session.getInstance(prop, null);
        Transport transport = session.getTransport("smtp");
        transport.connect("mion.elka.pw.edu.pl", 587, registerLog, registerPass);
        transport.close();
        return true;
    } catch (NoSuchProviderException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    } catch(AuthenticationFailedException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    } catch (MessagingException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    }

I set connection timeout to 1000 ms = 1s but it's ignore. When i debug and set wrong username and password i catch

javax.mail.MessagingException: java.net.SocketTimeoutException: Read timed out

not after 1000 ms, but after 5000*60 ms = 5 min

What is wrong ? How can i reduce timeoute ?

I resolve my problem by changing to the newest version of JavaMail (to JavaMail 1.5). I write about it there: http://openejb.979440.n4.nabble.com/Which-version-of-JavaMail-td4665285.html

thank's everybody for help, specially to Bill Shannon :)
