Once in middle school in the late '90s I created an email loop between two free email accounts that forwarded an extra copy of the email every iteration. It was an experiment out of curiosity and mischief. I don't think the server actually went down when I started the loop (at least, I can't remember if it did) - since the mailbox would have failed up and messages fail to be delivered. I think I was hoping to produce an "email cannon" similar to yours - an email spammer to be directed at whoever I liked.
