Expert in Cloudflare, cPanel, GoDaddy, WordPress Contact Forms and MX Exchange 2010

We host 3 WordPress sites with GoDaddy and 2 contact forms on each site. All contact forms worked perfectly until we implemented a Cloudflare SSL on our sites. Ever since, we’ve been having issues with the contact forms on our main site to flow through to a specific (Distribution List) e-mail address. (FYI - We host our own on-site MS Exchange 2010 server). Contact forms on our sub-domain are set up to forward to a (Distribution List) e-mail address on our main domain. This works fine. Strangely, WHAT’S NOT WORKING are the two contact forms on our main site which are directly set up to go the same (Distribution List) e-mail address as the contact forms on the subdomains. We need an expert that’s able to resolve the above issue, as well as to check if everything is set up correctly on Cloudflare (gray vs. orange clouds, etc.) and cPanel.
