Securing Email Delivery
The Email Delivery service offers an SMTP endpoint, secured by a password generated in the Console. The SMTP password is required for sending emails using Email Delivery. Oracle recommends that you create a separate IAM user for SMTP. This user must have manage permissions for approved-senders
and suppressions
resource types. Oracle recommends that you securely store the SMTP credential, and periodically rotate it. For more information about generating an SMTP credential for Email Delivery, see Create SMTP Credentials.
