Let’s we have two Email providers, one is hotmail.com and other is gmail.com , XYZ is a registered user in gmail.com and ABC is a registered user in hotmail.com.
XYZ signs in to his Email account in gmail.com, he then writes a mail to the email@example.com and sends the message.
But what happens behind the curtains, the Email from the computer of firstname.lastname@example.org is forwarded to the Email server of gmail.com. Server of gmail.com then looks for yahoo.com on the Internet and forwards the Email of the hotmail.com for the account of email@example.com. Hotmail server puts that email in that account.
ABC then sits on computer and signs in to own Email account and see the message in Email inbox.

Gmail, yahoo normally do not reveal sender's IP address. But when we send an email from a php script, the headers might reveal Sender's IP. The conclusion is that answer to this question depend on email service providers and the way how email is sent.
