Sorry I must have explained incorrectly. I know its not Fedex sending me the emails. It just annoys me that the scammers use the company logos. I used to work for a very large Bank and I got scam emails saying they were from the bank that I worked for so I used to forward them on to our security teams.
So I have started doing it again, i.e. if they use a company logo I will forward it on to that company. Is that just a waste of time?
