How to change the 'From' in auto email confirmation

Hi, Cory here.

Was testing PC registration and everything is going well. PayPal worked. Auto emails worked. Great!

My only concern is the 'From' part of the email with the auto emails using your PC(Protected Content) plugin. It shows "From: WordPress <wordpress@faa-s-t.newedealsdaily.com>".

How can I change this to show my clients Company Name and email address?
