I worked with a technician this morning at GoDaddy. Tried many of the items above. The fix for me was modifying the “SPF record”. The technician stated it was outside their scope to correct and that a webmaster should know what to do. He did fix the issue but I reviewed the documentation after being armed with that knowledge and came across this article: About SPF records – Google Apps Administrator Help at the bottom of https://contactform7.com/best-practice-to-set-up-mail/ . I hope this helps resolve your issue. There are many other forums that have been closed so I was unable to update the individuals. – Mickey
