Full Headers, not basic headers on email - have a timestamp on them and information on where the email originated. If your email program allows you to see the full header, please post a screen cap of your headers along with the email response received from info@war.systems with your email address redacted (blacked out).

Some programs won't allow you to see the full header, but you should be able to access it in Gmail by clicking the 3 vertical dots to the top right of the sender's email, then choosing "Show original."
