All of the above...
Yup, I agree with all posts. Spam gets identified & ignored. The prob, as far as I'm concerned is those mails which appear to come from friends. And, yes, SD, I know that I can trace the sender - after I've opened the mail and found another spurious one.
I just wondered if there was a magic bullet other than wot I dun - see my first post... It's just a poxing nuisance.
