APC UPS Power Management (daemon)

apcupsd provides UPS power management for APC products, including most BackUPS series models (including USB), SmartUPS V/S, SmartUPS (NET/RM), and Matrix series. It controls and monitors the status of UPS and allows your computer to run for a specified length of time on UPS power, and then executes a controlled shutdown in the case of an extended power failure.

High-performance mail transport agent

Postfix is Wietse Venema's mail transport agent that started life as an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.
