How to get syslog to trigger an event.

[Per-Erik Persson <pere_(_at_)_fos_(_dot_)_su_(_dot_)_se>]

A long time ago I used the following setting in syslog.conf
*.crit               |mail -s "blablabla" bla_(_at_)_bla_(_dot_)_bla

But it doesn't seem to work nowdays.
I suspect the chrooting of syslogd might have something to do with it.

Is there some other very obvious way that I have missed to get a hint 
from sensorsd that some of my computers are overheating.
I suspect my AC is not cool enough to get me thru the summer.
