         print("Connection established....");
         print("<br>");

         //Creating mailboxes
         $newmailbox1 = "{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX.test_mail1";
         $newmailbox2 = "{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX.test_mail2";            
         $res = imap_createmailbox($mailbox, imap_utf7_encode($newmailbox1));
         $res = imap_createmailbox($mailbox, imap_utf7_encode($newmailbox2));

         //Retrieving the contents of mail boxes
         print("List of mailboxes: ");
         print("<br>");
         $list = imap_getmailboxes($mailbox, $url, "*");
		
         foreach ($list as $key => $val) {
            print_r($val->name);
            print("<br>");
            exit ("Alerts: <br>" . $alerts = imap_alerts() ."\n");      
         }
      ?>
