I must have signed myself up to something dodgy, I cannot get rid of spam emails , I keep marking them as spam and do not open them, getting lots every day, do I have to change my email address or is there anything else I can do.i am with bt.
Are they going into your spam/junk folders, if so then just stop opening those folders, you should only need to check them if a mail you are expecting hasn't turned up. You can't really stop Spam these days as they just send to every possible email combination they can come up with, so even if you change your address chances are things will just be the same.
If you access your email account via BT's website then there's nothing else that you can do. If you access it via an email client (such as Outlook Express, Windows Live Mail, Thunderbird, etc) you can install the excellent Mailwasher:
