When I was installing it I provided my personal email. Now I changed it to my admin email via admin panel, then I changed it in smtp settings i.e. I changed it everywhere I could find in the admin dashboard.

The problem is that when users sign up it is still says: If you don't receive then whitelist MYPERSONAL EMAIL 

I don't want users see my personal email. It looks like the var name is $site-email but I can't find the source file in which I can change it. I tried to hard code my admin email in base.xml in langs.zip in updates but there are too many of them.
