A spammer is sending me at least one email message a day with attachments. I'm managed to get his email address and ip address. His isp is Charter.net (or charter.com). I've tried sending him an email but (surprise) his email box is full. I've tried forwarding the spam to firstname.lastname@example.org with warnings about his spamming telling them to stop him/her, warning of legal action, etc. but they haven't done anything. How can I stop this? Any ideas are appreciated.
