The output returned is normally returned to the sender as an error,
depending on how the transport is configured.
Oh, I think I see what you are really asking. If you write
pipe /some/script
in a filter file, it does *not* run the pipe right there. It simply sets
up a pipe delivery, to be done along with all the other deliveries.
Think of a filter file as a "conditional .forward file".
