I followed the instructions, left the email server blank, then tried specifying the server, which was confirmed correct with the provider, and nothing has worked yet. On the page for the web form, shouldn't there be a path specified for the script in the action=""? It seems like it is not seeing the settings. After I click on the submit button it does respond with the "thank you" page, but I don't receive an email to either of my test addresses. I didn't change anything else but the email server and the email address in the CAPTCHA settings.
Puzzled and Frustrated
