I understand why it is dangerous to use tainted data in constructing filenames so I can no longer run a command containing the local_part, e.g.
data = |/home/exim/scripts/$local_part I see that it is also an error to use, e.g. data = |/home/exim/scripts/my_script $local_part In this case the script is fixed and the tainted data is being used as an argument. Is that still dangerous? The script can pick up the local_part from the LOCAL_PART environment variable.
