When I got this email, I was not sure whether I should laugh or cry:
Thank you for writing to MSN Hotmail Technical Support.
This is Nat and I will be assisting you today.
Due to safety and security reasons, we are not authorized to open any attachment. If you have received an unsolicited e-mail with the Hotmail domain name in either the header information or the body of the message, please copy and paste the complete and unedited copy of the e-mail to your reply to us with full message headers exposed so that we can investigate each instance.
I probably would have given Nat the benefit of the doubt if the attachment was something sketchy like "microsoft.exe." Had he looked at the "complete and unedited copy of the e-mail" that I had sent to him, he might have realized that the attachment was text-based.
