Not quite. Exim does not run pipes via a shell by default. If you want
to use shell features, such as piping to another process - as you have
done there - you must call a shell explicitly by something like
pipe "/bin/sh -c '......'"

Yes. Well, I suppose so - in the latter case the local delivery program
will read an empty stdin. Assuming it then does nothing and ends
successfully, then it will be as you say. If it grumbles because it
hasn't got any input, and ends with an error code, then the whole thing
will end with an error code.
