There are advantages to hosting your own e-mail server over using an outside provider. It gives you flexibility, letting you customize the e-mail options whenever you need to. If you have confidential data in your e-mail, storing your messages on your own server will give you peace of mind.
When using an outside e-mail server, such as an Internet service provider or an offsite host, users in your building who e-mail one another send traffic out through your Internet connection and back. This can slow the Internet connection in organizations with limited Internet bandwidth. Using your own e-mail server keeps internal e-mail traffic off your Internet connection.
This chapter describes setting up e-mail service with all the trimmings, including spam and virus blocking and domain name service (DNS). I also show you how to change the location of the data store — an important task if you don't want to run out of space on your boot drive.
