You hadn't uploaded the blank2.php page... so I set it back to the blank.php page so I could test it. I also updated the settings which is why they appeared to be the same when you checked. Did you get the emails from yesterday that I tested? I did.
Also you had the FROM address set to an email address from a different domain that matched the TO address. The incoming email server would be able to see that it didn't actually send that email and could block it as spam. You should also use the same FROM address from the working email.
