Displays the current set of target servers to which mail can be sent that are configured or resolved from the TargetServer statement.
Helps you determine how mail is being processed off the JES spool file.
Helps you monitor the mail that is being sent to target servers to determine whether mail is being delivered, is being placed in undeliverable states, or is being tried again through long retry queues. This command also helps you determine the list of target servers, their attributes, and the number of mail messages that a target server is accepting.
