our support person indicates the following needs to be done by Cloudflare to rectify this
second, you need to have Cloudflare setup an spf record as such:

v=spf1 ip4:209.198.84.234 a:walshelectric.com a:walshelectric1.com include:mfg.siteprotect.com –all

Welcome to the Cloudflare Community :logodrop:

You will want to start with this Community Tutorial.

Add a TXT record, with this information:

Type: TXT
Name: @, or walshelectric.com
Content: v=spf1 include:mfg.siteprotect.com –all
TTL: Preferably set it to something like 12-24 hours, as mail related records likely do not change that often.
