Linux Mail Server - run external programs?
Hello, I have a surveillance DVR which sends email messages on multiple alarm events.
I have a (separate) spare Linux box and I want to install a Mail Server to take further actions. For example, I want to control some external hardware (buzzer, lamps, door locks etc) through parallel port. Is there any Mail Server which could filter the incoming messages (by address or subject) and run external programs accordingly?
I prefer a Mail Server over a Mail Client because I want to run those programs (almost) in realtime (no polling interval).
Thanx in advance for any clue.
