Directly enforces authorization checks on functions such as /srms/script/admin/core/update_smtp.php to block unauthenticated remote access.
Restricts privileges so that SMTP configuration functions cannot be reached or modified by entities lacking explicit administrative rights.
Requires successful identification and authentication before any access to privileged management endpoints is granted.
