Which email setting is recommended for the production environment?

In a production environment, the recommended email setting is SMTP (Simple Mail Transfer Protocol). This is because SMTP is a widely recognized standard for sending emails over the Internet. It allows for reliable, efficient, and secure email delivery, which is crucial for operations that depend on timely notifications and communications.

Using SMTP, IdentityIQ can connect to an email server to send out alerts, notifications, and reports necessary for identity governance processes. This ensures that stakeholders receive important messages and that the business processes reliant on these communications operate smoothly.

Other options do not suit production environments as effectively as SMTP. Redirecting to a file is generally used for testing or debugging purposes and does not facilitate immediate and reliable communication. Redirecting to email might imply the use of a less formal or secure internal email system, which may not guarantee timely or secure delivery. The choice of "None" does not serve a purpose in a production setup as some email configuration is essential for operational communications. These elements reinforce why SMTP is the preferred approach for managing email settings in a professional context.
