    Reading mail contents

      I am trying to read inbox using java mail prgm but it is showing some exception as

      DEBUG: setDebug: JavaMail version 1.3.1
      DEBUG: getProvider() returning javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsystems, Inc]
      DEBUG POP3: connecting to host "pop.gmail.com", port 995
      ---oops exception caught------javax.mail.MessagingException: Connect failed;
      nested exception is:
           java.net.SocketException: Connection reset

      my java prgms are

      public class ReadMail {
           public static void main(String[] args) {
                String email = "das.kumar88@gmail.com";
                String toAddress = "das.kumar88@gmail.com";
                try {
                     String subject = "Cluster Software Solution";
                     String message = "Hi, This mail ur getting from java main class";
                     try {
                          FunctionReadClass mailClient = new FunctionReadClass();
                          mailClient.postMail(new String[] { toAddress }, subject, message,
                          System.out.println("Mail sent succesfully");
                     } catch (Exception e) {
                          System.out.println("---oops exception caught------"+e);
                } catch (Exception e) {
                     System.out.println("===========" + e);
