What is SPF?
SPF (Sender Policy Framework) is a DNS-based email authentication method. It lets domain owners specify which mail servers are authorized to send email on behalf of their domain.
This generator builds a single v=spf1 TXT record from the mechanisms you add. Combine include: entries for your providers with ip4:/ip6: ranges, then end with ~all (soft fail) or -all (hard fail). Already have a record? Check it first to see what is published.
SPF Record Syntax
An SPF record is a TXT record published in DNS. It always starts with v=spf1 followed by mechanisms and modifiers.
