I am writing a program which retrives the mails from mail server onto the hard
disk of the client like outlook. But i dont know how read this mail.

Properties props = System.getProperties();

props.put("mail.pop3.host", host);

Session session1=Session.getInstance(props,null);

URLName url = new URLName("d: est");

Folder folder=session1.getFolder(url);

But gives an error Provider not found. Can i apply javamail to access mails stored
other then mail servers (i.e. without protocols).
