Chapter 5: Mail
The Debian installer takes you through a standard script before configuration. Fol-
low the standard setup routine until you see a graphic screen asking you to choose
the type of installation you want. The screen will look like this:
( ) Desktop Environment
( ) Web Server
( ) Print Server
( ) DNS Server
( ) File Server
( ) Mail Server
( ) SQL database
( ) manual package selection
Don’t select any of the options; you’re not going to use the default Debian mail
server (Exim) because you’ll install Postfix instead. Just press the Tab key and click
the OK button that comes up. Debian’s installer will then proceed to download and
install packages. During the downloads, it will present one more graphical screen
asking if you want you to configure Exim (Exim-config). Choose “no configuration.”
Then answer
yes when it asks you, “Really leave the mail system unconfigured?”
The Debian installer will continue downloading and configuring packages. When
Debian finishes its job, you’ll see a screen thanking you for using Debian.
At this point you should remove some unnecessary programs using Debian’s apt-get
utility. If you decided to use another distribution, you can delete the packages
according to its procedures. Under Debian, run:
# apt-get remove lpr nfs-common portmap pidentd pcmcia-cs pppoe \
pppoeconf ppp pppconfig
Now, disable some service scripts:
# update-inetd --remove daytime
# update-inetd ...
