Select new subsystem for Simple Mail Transfer Protocol server jobs

The stage needs to be set just so.

You can specify a separate subsystem for the Simple Mail Transfer Protocol (SMTP) server. This should increase performance, because the need to share resources is eliminated.
To specify a separate subsystem, complete the following steps:
1. In iSeries™ Navigator, expand your iSeries Server > Network > Servers > TCP/IP.
2. Right-click SMTP and select Properties.
3. Click the Additional Parameters tab.
4. Select the Subsystem description radio button.
5. Enter the new subsystem's name and the library where the subsystem description and job queue will be created.

The program will check for existence of the specified subsystem. If it does not exist, the program will create it along with routing table entries, auto-start job entries, pre-start job entries and job descriptions. Even if the subsystem does not already exist, the library for the subsystem description and job queue must already exist. When the startup job for the server is processed, it will specify the parameters for the newly created subsystem and then submit the server jobs for batch startup in that subsystem.
