email search listings notifications not working

[1or24u]

I have about thirty search email notifications listed and regularly every day I get notifications coming through of items I am searching for, however, in the last 2 days these have ceased and also a couple of recent messages from clients using the Ebay message system have failed to show in my email box as they normally do although they are in my ebay message box. I have checked that my email address is still current in my Ebay personal details section, which it is. I have also checked my search items page and all searches are saying "currently receiving email notifications"? I also sent a couple of test emails to my email address and they came through no problem and I am getting emails from other sources to this same email address as well, very strange. This must be an ebay fault but I can't seem to figure it, any ideas anyone, thanks Phil
