Right. It sure is something people can do and I think that
@fixme accurately alludes to the general nature of things,
but it's not clear to me how this got specifically bound to
questions relating to a high-volume box.
You are right in pointing out that you want to avoid
such things and user, eg, qmail-users. But on a HV box there
are many things you want to avoid.
