Yes, the email has been in my address book for a long while. I have also replied to him using the reply button to ensure the correct address. i am with Wanadoo and using Outlook 2003 he is with Tiscali using Outlook Express.
VoG™ Thanks may need to get back to you on that since I now cannot raise him on the phone. I have sent e-mail to others and got replies so there is obviously a glitch between my relative and I. Perhaps he is trying to tell me something!!
Just a further thought could my relatives ISP be blocking me? I sent 3 photos a couple of days ago and stupidly forgot to resize them. As a result they went out at a total of some 3megs. It is since then my sending to him has failed.
