And note that *even* if you receive an email that comes from a certain address,
it does not guarantee that the email comes from the owner of that address.
It is easy to impersonate an email address. For example, there are many scams
that look like they are sent from your own address, to make you believe it has
been hacked.

Luckily, we have technologies (SPF and DKIM) that can guarantee an email is sent
from the owner of the sender address, and if an email doesn't pass SPF/DKIM,
it's very likely to be blocked by your spam filter. But this is still possible.

A fortiori, if you receive an email signed "John Doe" but the sender
address isn't John Doe's usual email address, it is very likely a scam.
