question about sending mail and postfix

[Adam Hardy <adam.ant@cyberspaceroad.com>]

This is possibly an exceptionally easy question to answer because I feel like 
all the documentation I've read about sending mail and postfix starts at step 2, 
and step 1 is just common knowledge that I somehow failed to pick up.

I have a new server online with lenny that I want to configure to send all its 
mail for root to my email address, and that's all. I don't want it to receive 
any email or relay or anything else.

I set this up a few years back with postfix and now trying to recreate this 
setup, I am running into the problem that the mail command isn't installed. It 
obviously doesn't come with postfix and there appears to be a huge choice of 
packages that I could choose from in the debian repositories, but isn't there a 
default? My guess is that my hosting service installed such a stripped-down 
version of lenny that I didn't get it.

Any enlightenment gratefully received,

Adam
