Someone sent an email logging into my yahoo account to a group of people. One of the recipients on a list was my friend Jim. His only address I had in my inbox was Jim@mac.com. I’ve got a call from one of the people on the list and he forward that email to me. I looked at the cc list and saw that Jim’s address was Jim@me.com. Is it possible that mac.com somehow converted itself into me.com on a route from my Yahoo account to all these people?
