Who handles email for example.com?

  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.                                              

Good to know
  Nothing to change here. These explain what the map shows.

  ·   The domain accepts no mail                                              
      It publishes a null MX record, which tells senders it receives no email.
        example.com MX 0                                                      
  ·   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.                                                                 
        *._domainkey.example.com TXT v=DKIM1; p=
