I also received this message today.
Like you state, could this be an insider, as the email I use dates back to 1998 the old virgin.net.
I would be interested to know if all the people that have received this threat message, have been in touch with VM before the message? I had reason to contact VM a couple of months ago, and found their help as good as useless. Reason being, my email account is the old virgin.net, which they had NO idea what I was talking about.
Perhaps if the message has been sent to users that have been in contact with VM, then another route to follow!
