I am having the same problem. I am geting the same e-mail two or three times. There seems to be no logical pattern as to who I receive the multiple e-mails from. I have read on another website that the problem may be with the ISP. However, my IPS claim it is not their fault. (They would though, wouldn't they?). I have also been advised that this may be caused by spyware and that I should run Adaware and HiJack-This. I will try this as a last resort, although I am not that convinced.
Anyone got any other ideas ????
