Rapidweaver 7.1.3 contact form will not send email

I get this message when trying to send from the built in contact form - We cannot verify that you are trying to send an email from this form. Please try again. I am using the Natural theme, a GoDaddy domain being forwarded to another DNS and then to my in house OSMac server which is hosting my website. I have tried email at GoDaddy, email being forwarded to, and email on my server.
How do I find what is causing this message. I have tried everything I can think of to try. Any suggestions are welcomed.

I have never used godaddy but they have restrictions on what email accounts you can send to from a form, check out this thread and see:
