Here's a test routine:
1. Log in as rland.
2. $ mail root -s "mail to root" </dev/null
3. Launch your favorite email reader ('mail' will do) and see if you
have a message titled "mail to root".
4. You should check out the Mail-Administrator and Mail-User HOWTO docs.
Debian installs exim by default, anything named 'sendmail' on a default
Debian system is actually a symlink to exim.
