Session session = Session.getDefaultInstance(properties); // Get a Store object that implements the specified protocol. Store store = session.getStore("pop3"); //Connect to the current host using the specified username and password. store.connect(host, user, password); //Create a Folder object corresponding to the given name. Folder folder = store.getFolder("inbox"); // Open the Folder. folder.open(Folder.READ_ONLY); Message[] messages = folder.getMessages(); for (int i = 0; i < messages.length; i++) { System.out.println("------------ Message " + (i + 1) + " ------------"); // Here's the difference... Enumeration headers = messages[i].getAllHeaders(); while (headers.hasMoreElements()) { Header h = (Header) headers.nextElement(); System.out.println(h.getName() + ": " + h.getValue()); } System.out.println(); } } }
