I no longer receive notifications from ebay

Hi I no longer receive notifications from ebay saying bid excepted been outbid etc. I have looked around the net and even rang ebay, but problem is not there end. I have checked spam and junk email filters and cant find a problem. The strange thing is I have changed nothing, and if it was working why would I change it. There are lots of threads talking about this but no answers. Hope someone fixes soon. I also did not have a problem when it was Hotmail only seems to have happened since outlook.com took over.
