Ah, okay. Is default_process_limit the correct setting to be looking at here? I have it set to the default of 100. The maxproc of the smtp unix service in master.cf is set to the default. I notice that maxproc of some other services in master.cf is set to 1 or 0, rather than the default of 100 (eg pickup: 1, cleanup: 0, qmgr: 1).
