SMTP-Send

The architecture of SMTP-Send comprises several key components designed for efficient and secure email routing on z/OS. The SMTP-Send daemon is the core process responsible for receiving email requests from z/OS applications, such as CICS transactions, TSO users, and batch jobs. The configuration manager reads and applies settings from configuration files, which specify SMTP server addresses, port numbers, and authentication details.

The logging service records all activities, errors, and audit trails, providing detailed information for troubleshooting and security analysis. These components communicate using internal z/OS mechanisms, ensuring high performance and reliability. The SMTP-Send daemon interacts with the z/OS system through native interfaces, allowing seamless integration with existing applications.

The configuration manager uses z/OS file systems to store configuration files. The logging service utilizes z/OS system logs for recording events. The product supports SMTP AUTH for authentication, and TLS/SSL for encryption.

The z/OS security infrastructure is leveraged for access control, ensuring that only authorized users can send emails. The architecture is designed for scalability and can handle increasing volumes of email traffic. The system is managed through the z/OS console and configuration files, with monitoring provided through z/OS system logs.
