function sendEmail(){// Send Mailbox Authentication Mail 
  var me = $("#sendAgain");
  me.time = 60;
  (function() {
    if (me.time > 1) {
      me.time--;
      me.html("2. Send Again Need (" + me.time + ")");
      setTimeout(arguments.callee, 1000);
      me.attr("onclick","");
    } else {
      me.html("2. Send activation mail again ");
      me.attr("onclick","sendEmail()");
    }
  })();
