Enabling SPF makes it so that mail servers are required to check if your domain is listed in your SPF record. SPF or Sender Policy Framework is a way for an administrator to help prevent spam. If the sender's IP address doesn't match the IP address in the SPF record, your mail server will reject the message and any associated spam checks that you have set up will be passed.
