How does one send a spam email that passes SPF and DKIM if one doesn't have access to the DKIM private key, or the DNS server to edit the SPF or DKIM records?

  • Open a Gmail account, send spam.
  • Buy a domain, setup SPF and DKIM, send spam.
  • Hack an SMTP server, send spam.

You can't... But you can register a domain and set up your own DKIM key and DNS records and then use it to send spam (until you get blacklisted, anyway). There's a cost to doing that, though, so it's less appealing.
