I'm using 1.5.2.8 Gravity Forms on WordPress 3.1. My form works fine and save entries as expected. However, the notification mail doesn't get sent when I specify certain email addresses in the 'Send to Email'. If I specify info@mydomain.com (the domain where I'm using the plug-in), I don't see a notification. If I use a Gmail address, I do see a notification.
I've disabled all plugins and retested with the same results. I also have Contact Form 7 which does send messages to info@mydomain.com.
Can you assist?
