We recommend that you create a Sender Policy Framework (SPF) record for your domain. An SPF record is a type of [[DNS ]] record that identifies which mail servers are permitted to send email on behalf of your domain.
The purpose of an SPF record is to prevent spammers from sending messages with forged From addresses at your domain. Recipients can refer to the SPF record to determine whether a message purporting to be from your domain comes from an authorized mail server.
