Most mail clients conveniently hide a ton of detail that most people
don't want to see.  The actual original message the mail servers see
usually includes the from address - the address of the sender.  If you
want to take a look at the full message, here's how for a few clients:

In Windows, Microsoft Outlook, fully open the message, click on "View"
then click on "Options" and look at the box "Internet Headers".  Look
for the from address of the message.

On a Mac, in Mac Mail, click on "View" then select "Message" and "Raw
Source".  Look for the from address of the message.

In gmail (Google's mail), open the message, click on "More Options" at
the right, click on "Show Original" at the right.  Look for the from
address of the message.

For your message, I do see your from address in the (usually hidden) headers.
