I finally found it in the 404.php.
https://codex.wordpress.org/Creating_an_Error_404_Page#Writing_Friendly_Messages%3C/a>
I just commented out the email part:
#mail($adminemail, "Bad Link To ".$_SERVER['REQUEST_URI'],
# $failuremess, "From: $websitename <noreply@$website>"); #email you about problem
I have looked through the plugins.. All settings, etc and I can not locate anything.
I have :
Akismet Anti-Spam
Contact Form 7
Contact Form 7 Skins
Hello Dolly
Limit Login Attemps
WordPress Importer
WP Mail SMTP
WPBakery Page Builder
