I have ordered stuff from a company that deals in quirky items, for a 19 year old granddaughter. I suspect one of them has somehow copied my e mail address as I received an e mail from "myself" - with an attachment I did NOT open. Usually if you highlight the "from" part it shows the true e mail sender. In this case the "properties" were exactly my own. I have W7 ant use Outlook as my e mail client. How can I trace the origin; can I get my ISP to check? - Talk Talk /Pipex?
I think I have found something. I highlighted the email by right clicking and then "Message Options" - it had a box with "Internet headers". It still appears to have come from me but I have a ip address that I will try to trace.
