Indeed. SPF and DKIM were supposed to reduce spam by ensuring that every sender was verified. Now, we have more spam than ever, and all the senders are verified (on short-lived garbage domains that are not yet on blocklists). The only DKIM failures I ever see are on legitimate mail from badly set-up lists.
