services.nullmailer.config.pausetime

The minimum time to pause between successive queue runs when there are messages in the queue, in seconds. Defaults to 1 minute (60). Each time this timeout is reached, the timeout is doubled to a maximum of maxpause. After new messages are injected, the timeout is reset. If this is set to 0, nullmailer-send will exit immediately after going through the queue once (one-shot mode).
