The odd thing is it's not his normal email address. It's of the form [2-letters, his initials][3 digits][letter s][4 digits]@ntlworld.com
He's been with Virgin for around 7 years and has used his normal ntlworld.com email address all that time. He's not aware of any other ntlworld email address.
Clearly he can just ignore the letter and let the mail box die. But he's curious to know what it is and what, if anything, may be in it.
Any suggestions where it may have come from? Is it perhaps the original email address before a more personalised one was created?
He's no idea of what the password is, I've suggested he go back to the original paperwork to see if there's any reference to this address. I guess he can try to login via web mail, and go through the forgotten password procedure.
