Frequently Asked Questions
SPF (Sender Policy Framework) is an email authentication method that specifies which mail servers are authorized to send email for a domain. It helps prevent email spoofing.
SPF helps prevent email spoofing and improves email deliverability. Many email providers check SPF records to verify sender authenticity.
A valid SPF record starts with 'v=spf1' and includes mechanisms like 'include:', 'a:', 'mx:', or 'ip4:' followed by '~all' or '-all' for policy.
'~all' is a soft fail (emails may still be accepted), while '-all' is a hard fail (unauthorized emails should be rejected). '-all' provides stronger protection.
