You'll have to explain in more detail, because what you posted so far makes no sense. That can't happen unless there some other connection, in you have similar names, or theres more connection between you than a single email.
AlbacoreA - no other connection, just one email is all i ever sent. His email is a comcast address, mine in eircom and our names are totally different.
Why are you worried your mails are going to him? Hes either forwarding his email to you, he set a rules, or has a virus. You obviously can check that isn't happening on your cmputer. If its a virus, either you've sent it to him, or perhaps its on his machine only. Mabe his emails are being sent to everyone in his contacts list.
Complainer, no hes not sending them to me and my address is not visible. Dont really like emailing him about it cos the man is in his eightys and i think he is doing quite well to be able to email
Has he incorrectly set your email address as his reply to address ? Do you only get mails sent in reply to his mails - if so this would be the most likely cause
