E-Mail on the Cheap

Free open-source e-mail servers can give you everything commercial e-mail servers provide, including antispam and antivirus facilities. Some open-source solutions, such as the Courier Mail Server, go further than simple e-mail services by providing groupware functionality, like group calendaring and scheduling.

So what's the catch? In addition to supplying your own hardware, you'll have to obtain the expertise to compile the code and install and maintain the software. In addition, you must be willing to rely on support from informal usenet newsgroups. If you don't have an employee who's a card-carrying geek with time to burn and a spare computer lying around that's got reliability written all over it, then open source isn't for you.
