Contact link not working rapid weaver 6

I believe I have a broken link in the contact email area of my Endeavor web site?
I am able to send myself an email from my iPhone to my email address hosted by my server company, but not able to send myself and email from the my website contact area. I customer emailed to let me know he had tried to contact me but it was not working.
When I opened the contact form settings it says tried that did not work. changed it to - did not work, tried another gmail email - did not work? By the way I republished after each attempt and refreshed the website and cleared all history.
