My mx record is causing problems. Some emails are not getting through my mailman listserve tied to my domain. When I looked up my domain name on leafdns.com, I receive the following message: FAIL: _dc-mx.aa4a59d0700c.domainname.com. is not a valid domain name. Yet, it claims my MX record IP(s) have proper PTR (rDNS) records. (Note: I removed my real domain name for the purposes of this message.)
I am also receiving an alert that says “This record exposes the IP behind your domain which you have proxied through cloudflare.” (I have read through some other examples of issues marked by this message and found no solution) All my other records are proxied with an orange cloud. I am on the free account.
