Setting it up can mean that you check these things on the receiving end. Big difference between self-hosting and accepting all e-mails and self-hosting and checking the sender's SPF and DKIM.
- trumpd 11y agoYou can check incoming SPF/DKIM/DMARC regardless of whether you implement it for your own mail. That said, it will reduce bounce-back from spam that forges your domain.
