We're using GoDaddy, and I have smtp.secureserver.net as the email server. Even when I check the "Use Additional Email Parameters:" nothing happens. And by that I mean the page doesn't refresh, there's no loading bar, nothing. So I thought maybe I was missing a js or php file that was supposed to submit the test email, but I checked and the site has all of the files up there. Anything else you can think of? I'll give you the credentials if you open up a private ticket.
