## 2.2 Aliases for administrative account

Linux system have several administrative accounts which received mail. It is a pain to manually log as one of those user just to check if there is any mail. This is a good idea to redirect those account to a real user (you ?).

Here is a list of those accounts

- root
- uucp
- news

## 2.3 The admin pseudo-user

On small site, there is a single administrator for the complete network. Instead of setting all those aliases pointing to him, you may save some time and point all to the pseudo-user admin which is itself and alias pointing to the administrator.

This may save time.
