@rajkinkhabwala please check why system is not sending confirmation emails ? @dushyant reports that he didn't get any email but can still join without confirmation link
I didn't get the confirmation mail the first time but it worked after I clicked on the "send again" button.
The first activation mail did come in eventually but, even though the time-stamp is earlier, it definitely came later. Very strange.
vistasp actually it might be in the server queue and the mail we were using at that time was using the local server and now it using other servers which much faster.
