No sending service shows in DNS for example.com: a null MX that says it accepts no mail, no sender 
in SPF, and a wildcard that answers every DKIM name.
Not checked: the crt.sh certificate log (read only with --ct).

NEEDS ATTENTION
  ● The domain accepts no mail
    It publishes a null MX record, which tells senders it receives no email.
  ● Every name under _domainkey.example.com answers with a key
    A wildcard record makes every selector look published, so keys there say nothing about which    
    services sign for the domain.                                                                   

WHAT WAS ASKED
  example.com: 25 CNAME labels, 2 pages

NOT RUN
  certificate transparency, crt.sh: read only with --ct (it also holds expired certificates)
