FAQs
What is SPF?
SPF tells receiving mail servers which systems are allowed to send email for your domain.
What is DKIM?
DKIM uses a DNS public key to verify that an email was signed by an authorised sending service.
Why do selectors matter?
DKIM records sit under selector._domainkey.domain. The selector depends on your mail provider.
Should I also configure DMARC?
Yes. DMARC helps receiving servers decide what to do when SPF or DKIM alignment fails.
