Indeed, that does sound odd. I've filed a ticket with my registrar and
for now I'm moving DNS hosting to my own nameserver but it may take 24
hours to update and propagate. Hopefully that fixes things.

MX is never an IP address; that's not even valid and not possible to
represent in DNS. It's always a name, and it's required to be an A
record, not a CNAME. Check MX for any other domain and you'll find an
A record.
