Just go to hackforums all ready. You do 0 research, 0 learning, and obviously have 0 knowledge. you would fit right in at that site. I mean i havent even TRIED to google this question and i can guarantee you could find out a TON about this with just a single search. I mean jesus email spoofing is one of the oldest tricks in the book, and that is not an exaggeration. The ONLY way you could not know this, or not find information on it, is if you havent even tried. I will not try for you.
