Not necessary. Just very highly recommended. I can still deliver my cron emails from a rando host successfully.

That doesn't rule out DKIM, which only requires the `From:` header's domain to list a pubkey and the email to include a DKIM signature from a matching private key.
SPF is the one that regulates which hosts a domain's outbound SMTP servers are on.
