Maxfiles Channel Option

Maximum number of messages a delivery job can process
Periodic delivery jobs normally attempt to process every possible message in the queue. The  channel option can be used to place a limit on the number of messages a delvery job will attempt to process. Message past this limit will simply be ignored. It takes a single integer argument and the default is infinite.

IMPORTANT NOTE:  is only meaningful when the (on-disk, rather than Job Controller in-memory) queue cache database is used; it has no effect on processes controlled by the Job Controller.
