Hi, about 6 months ago, my BT email address started sending out spam to whole address book. I deleted all my contacts, all my old emails, spoke to BT who informed me that my address would be deleted within a couple of months! But it hasn't been, as I received a spam email from this address yesterday. How do I go about deleting this address. Any help would be gratefully received.
It is more likely that the email address has been spoofed rather than it sending the emails. If your account was previously hacked all your contacts addresses will have been harvested by the hackers and they are now free to use them anytime they want. Presumably you have told your contacts to treat anything from that email address as spam and to bin it. If not you should do that now.
