You’re minding your own business and one day you get email
from someone you’ve never heard of and they’re asking you to
stop sending them email. Or worse, they’re angry. Or worse
yet, they accuse you of sending them a virus! But you don’t
know them, you’ve never heard of them, and you know you’ve
never sent them email.
