Linux as a Backup E-mail Server
Setting up a fall-back e-mail server using a Linux system running on older hardware is an excellent tool to preserve incoming e-mail in the event of a disaster on your primary server. While I am backing up a Microsoft Exchange server, the same technique can be used to back up an SMTP server from any vendor. Setting up the fall-back server costs nearly nothing other than the time required for configuration. Having a very stable system completely independent of the rest of our network has also proven useful. Since I first configured bartleby, I have set up a collection of relatively simple scripts to watch other services on our network and page me in the event of an irregularity.
A fall-back e-mail system is a good way to sneak Linux into a low profile but “mission-critical” application in your organization. Once you've proven Linux is a “real” operating system to any skeptical decision maker, you can begin to utilize it in higher-profile roles.
