It changes it only in that it becomes a *lot* easier for you to track down
which of your users has a compromised machine. (It's a lot easier to just look
at the Received: headers than have to take the hostname, chase it back through
your logs, and all that - especially if the user is roaming and just caught
something over their Aunt Tilly's unsecured wireless access point....)
