There is a very different set of circumstances where something similar
but a bit different would be needed. That is when the police or
judicial authorities require an individual's email to be "tapped" as
evidence. I believe that in some countries this could be required --
in the same way as post can be opened and phones tapped, with a
suitable court order -- for example to break a ring of child
pornographers or fraudsters. Whatever one thinks of this, if the law
requires it, it needs to be done _without_ informing the suspect. Of
course the archive needs to be private -- ideally only accessible by
the police / examining magistrate.
