I have been doing cleanup in our CiviCRM, like merging duplicates and fixing errors. I changed an email address for one contact that I (incorrectly) thought was wrong, but I immediately heard from the person to let us know that the original email was correct. He responded to an automated system email that looks like the text below. I had no idea that it would trigger this notice, and have not been able to find the setup for it anywhere. Where is the admin page that controls or edits these notices? Civicrm 5.38.1 on Wordpress 5.7.2.
