What can I do with someone who continuously spams me via my website email address, that is forwarded to my personal email address and at my actual personal email address ? I deleted all of the known email addresses he has used to sign up to my newsletter, etc., but, he keeps inventing new email addresses and sending me spam mail.

If I could contact the Police or FBI and catch him I would. I do know his name, however, but, I don't know what city he lives in.
