Like Lomoto, Ive been getting these too - ever since Tiscali took over Pipex (who used to be one of the better IPs I was told 6 years ago), the spamming has been getting steadily worse. I suspect most of the problem is due to what Mr L says above but is there any straightforward way of stopping it, rather than using a different e-mail address as changing that from a business standpoint would be a real headache?
