Email headers can be forged, and are not reliable. But the more important thing here is what do you hope to accomplish should you actually prove that all three messages were from the same person?
I am looking for some help from all the computer pro's out there. I am head of a homeowners association and there is this guy who we kicked off the Board for about 50 different reasons. We have a community message board, which he was kicked off as well, but what I think it happening, is he is making new accounts, posing as other people in the community, and then trashing the HOA Board with all the same arguments. I got a hold of a couple emails he send and turned on my hotmail option to see all the email info. Below is three emails, the first being from his real account to me, the send is from his wife to me (so we know these two came from the same computer) and the third is supposed to be this ?new guy?. Can anyone with experience in this look at this and tell if all the emails came from the same computer? Please see each email is sent from 75.51.224.67..Does this mean they are come from the same computer?
