How to enable SPF and DKIM in cPanel
Open Email Deliverability in cPanel. cPanel will check your domain and show whether SPF and DKIM records are valid. If your DNS is hosted on the same cPanel server, you can usually repair records automatically. If DNS is hosted elsewhere, copy the suggested SPF and DKIM records into your external DNS provider. SPF tells receiving servers which systems can send mail for your domain, while DKIM signs messages to prove they were not altered. Correct email authentication reduces spoofing and helps messages avoid spam folders.
