I am in a dispute with someone. Months ago he illegally accessed my yahoo account and forwarded a private message to a third party, thereby making it appear that I had sent that email (we discovered that his IP was the real sender of the email --- he was deliberately attempting to frame me!).
But we have confronted him with the evidence, and in a really lame attempt to lay some kind of cover story, he has recently sent me more emails from his yahoo account, but the IPs in the headers are from other countries. So I think he used proxy servers to do it. It appears he is trying to lay some precedent for being
Thanks for your question sandyspook.
I'm not an attorney so I can't offer any legal opinion, but, if the original offending email has his real IP in it as the sender, all of the additional emails he sent using proxies shouldn't mean anything. He might suggest that someone else used his IP by proxy but, unless it was setup to accept proxy connections, it wouldn't be possible.
