Dear admin.Can't thank you enough for your replies.there's one more question,that suppose in windows someone names her/his computer as 'charlie' under my computer description option.will that show in the ip address if that person sends me email?when we go to my computer and under properties option it shows computer name and then there is an option which is my computer description or my computer name which can be edited to any name.if suppose the person has named his computer as 'charlie' and that person sends me email from that computer.will the IP address show that name?
