I've never used shadow_transport so can't answer your question directly.
You could also consider the "unseen" option, so that the mail continues
to be processed even when your procmail transport succeeds.
You are trying to filter spam; you may need a test in localuser so
that something different happens if procmail finds any, otherwise this
could just by-pass the filter ?
