The imsimta start command starts up detached MTA processes. If no component parameter is specified, then the MTA Job Controller and MTA Service Dispatcher are started. Starting the Service Dispatcher starts all services the Service Dispatcher is configured to handle, which usually includes the SMTP server.
The services handled by the MTA Service Dispatcher must be started by starting the MTA Service Dispatcher. Only services not being handled by the MTA Service Dispatcher can be individually started via the imsimta start command. The Service Dispatcher may be configured to handle various services, for example, the multithreaded SMTP server.
