i had somehow clicked on something with Bt to stop spam. trouble is i recently realsied that it was intercepting genuine emails as well. I found I had 796 unread emails and that was for one month and no idea how many in the past had been deleted.
Amazed at the number of them from banks I have never dealt with asking me to confirm my details. i guess for every ten thousand they email there is one

that will enter their details.
