After adding some of my domains (hosted at Opalstack) to my Cloudflare account, I notice in the Cloudflare dashboard that they each have a couple of MX records which I hadn't expected to exist:
MX www mx1.de.opalstack.com
MX www mx2.de.opalstack.com
(The domains also have the expected complement of MX records defined on the domain name itself)
I assume that these "MX www" records are harmless and would only come into play if anyone tried to send email to "somebody@www.mydomain.com" ... which of course should not in general happen.
Nevertheless, two questions
(1) just to tidy things up, is it worth deleting these "MX www" records?
(2) the api function at my.opalstack.com/api/v1/dnsrecord/list/ does not list these "MX www" records. Shouldn't we have a way of finding all the DNS records defined for our domains?
