Explanation

An SPF record prevents other servers from spoofing your domain and getting your addresses flagged as spam. You must have this in the external zone for the domain you want to protect. What Is An SPF Record? Sender Policy Framework (SPF) is a security standard that has been implemented to stop forgery of sender address. Domain owners can say "I only send mail from these servers" which helps to separate forgeries from real mail by using SPF record. https://hosting.intermedia.net/support/kb/default.asp?id=1010
