Hello Gary,
Thanks for sharing the email header, going over that message header it seems the owner of the gmail account is forwarding their email
over to your own email address, the fact that you did not receive the password reset I triggered indicates this. You will have to send the user more
emails regarding the issue and hopefully they take action. I would link them the following article. https://support.google.com/a/answer/2491924?hl=en
Best of luck.
