We’re excited to announce that we will be adding DomainKeys Identified Mail (DKIM) support to Proofpoint Essentials. You will be able to add DKIM signatures to outbound email that will ensure destination email systems trust emails that are sent from your domain. This update is expected to be available to all customers across all packages by December 14th, 2020. No actions are required to receive this update. 

For more information about deploying DKIM, just check out our how-to.



What Is DKIM?

DKIM is used to help prevent entities from sending emails that look like they are coming from your domain. When you configure DKIM, you are authorizing your domain to be associated to an email by using a digital signature. External email systems that receive email from your domain can use this signature to confirm that the email legitimate.
