Well, keeping things encrypted helps, especially backup disks - one site was being generally harassed and may be convicted because of possible child pornography that the sysop had deleted but was still on backup floppies in his re-use bin. (Police got a 15-year-old kid to log in for them and find some adult material, but dropped that attempt probably because it would have been thrown out as entrapment; the child-porn gave them a much nastier charge to use to steal the computer.)

On the other hand, making sure your users *have* email on the system, especially mail in transit to other systems, is good protection, since the ECPA limits what they can do with it.
