Education is incomplete.
To wit, where I used to work at least two outside engineers (not IT, construction) routinely emailed documents from unrecognized accounts (home? phone? WTF?) and subject lines like "heres pdf for filtration project plz review". The email itself would typically contain no text, just an attached document.
It was a great way to prep an organization for successful spear-phishing.
Idiots.
