mykill.net does NOT send out emails to unknown people / accounts. If you get an email from this domain and you are NOT expecting it, or the "subject" makes no sense AND/ or has an attachment (zip), it is a spoofed email. Do NOT open it. View the full header to see the IP address of the sender. Then, search it on the web. This will confirm just what I said. I get spoofed emails from my own domain as well, so I know how annoying spoofers / spammers are.
