This email was received into my neri_sarah@hotmail.com from mailer-daemon@googlemail.com . It would suggest that I sent that email to neri_sarah@aol.com, but I didn't. I don't even have that email address. Also, there was an attachment on the email which I haven't opened as I don't want to release a virus if one is attached. I'm assuming they want me to think it's the unsent message which failed delivery. My concern is that mailer-daemon@googlemail.com is a valid service to my knowledge? So is someone hacking mailer-daemon to send these fake emails? Or is this actually a fake email address? And why would it be sent from googlemail when the emails are between Hotmail and AOL?
