We recommend that you create a Sender Policy Framework (SPF) record for your domain. An SPF record is a type of Domain Name Service (DNS) record that identifies which mail servers are permitted to send email on behalf of your domain.
When a recipient's mail server receives a message from email@example.com, it can check the SPF record for example.com to determine whether it is a valid message. If the message comes from a server other than the mail servers listed in the SPF record, the recipient's mail server can reject it as spam.
If your domain does not have an SPF record, some recipient domains may reject messages from your users because they cannot validate that the messages come from an authorized mail server.
Please refer to the VCG User Guide for information on creating an SPF record.
If VCG manages your DNS record, please contact VCG Client Support for information relating to creating your SPF record. If VCG does not manage your DNS, please contact the company that manages it to inquire about creating an SPF record. If VCG is hosting your email, you will need to include VCG's hosted mail server information (please refer to the VCG User Guide).
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.
