Pendingignore Channel Option

Pending delivery job check (OpenVMS)
On some systems processing of delivery jobs is implemented through the use of an existing system queuing facility. When such facilities are used there may be no direct relationship between queuing a delivery job and proccessing a specific message or messages - a single job may process anything from a single message to all pending messages in the channel queue. The variability of this relationship can result in excess deliver jobs being queued, so the MTA normally checks to see if a job already exists that will process a given message before queuing another one.

The  channel option provides a means of controlling this check on a per-channel basis. It requires a single integer argument specifying the number of pending delivery jobs to ignore before assuming that sufficient jobs are present to process the message being enqueued. The default value of this channel option is 0, meaning no jobs should be ignored.

Currently the  channel option is only meaningful for PMDF running on OpenVMS. Use of this channel option is rarely a good idea since it usually leads to excess delivery jobs being processed and possibly excess delivery attempts being made.
