Create a script. Instead of running deliver directly, run something
like:

#!/bin/sh

deliver $*
err=$?
if [ $err != 0 ]; then
  echo failed | mail postmaster
fi
exit $err

This should never happen. The worst that can happen is that deliver
returns temporary failure and its delivery is attempted again. Although
if deliver crashes, some MTAs treat it as hard failure rather than
temporary. You could prevent that with a wrapper script too.
