How do you determine origin af an Email?
The From: and To: parts of an email message are whatever
a sender wants them to be. Especially if they are not using a
standard email program.
A received email includes header information detailing its
origin and the path the message took to reach you. You can access
this information from many email readers. For example:
- In Yahoo mail, click on More and select View Raw
- In Gmail at the right of the reply button, click the down
triangle and select show original.
- In Thunderbird, choose View > Headers > All
- In Microsoft outlook, find the Properties or
Option, Show Options or Message Options and Header
information appears in the Internet headers box.

Every mail reader has its own way of doing things. Try Searching
with "How to Get Email Headers" for specifics. As of May, 2017,
mxtoolbox.com has a nice list covering many mail readers.
The email message headers have information mostly provided by
the email system. Of interest are the lines starting with
"Received: by " and "Received: from " . They describe the
origin and the path taken by the message to reach you. The first
one usually connects to the original sender where the message first
came from. The last one is normally the mail server from where you
received the message.
