Monitoring the status of SMTP using the TSO SMSG command

The TSO SMSG command provides an interactive interface to the SMTP server to do the following:

Query the operating statistics of the SMTP server
Query the SMTP mail delivery queues
Perform privileged system administration tasks, such as shutting down the SMTP server and enabling or disabling various tracing and debugging options

Responses to commands are sent back to the originator of the command using MSG commands (or MSGNOH commands if SMTP is running with privilege class B).

Restriction: SMSG SMTP is not supported in batch mode. SMSG SMTP uses VMCF and the PASCAL interface to queue information and does not print the information to a DD card.
