Yeah... Change logs and the results from rkhunter and its ilk, aren't
really the sort of messages I want being sent out to some random user
on the internet.

At present, I have all remote delivery disabled. At least until I have
the patience to try and figure it all out again.

It's also hard taking this system offline to test a new mail
configuration. Everyone else in the house starts screaming at me if I
do that, because the internet connection runs through my machine.

The only downside to this configuration, is that every month the linux
counter script tries to email home and shortly thereafter I get a bounce
message in my inbox. One day..... *chuckles*
