Sending email alerts

[Blisk]

I have installed on Centos a email server which doesn't send my server alerts, like when yum updates, clamav update, etc. Is there a way to somehow setup external mail server to send this alerts? Or there is some other way to get those alerts by email?

I looked into something similar a while back and decided if i was sent a mail for everytime something happend I could end up with a whole bunch of spam ..... but i was looking after 5000+ servers at the time

In the end this is what i ended up doing:
I set-up monitoring ( Zenoss ) to query my servers
Then run a bunch of scripts out of cron.daily to keep things healthy (yum update etc)
Have zenoss check for errors as well as verify that each of the scripts as been run in the last 25 hours.
Finally configure syslog forwarding to your Zenoss server for critical alerts

You will have quite a nice setup with that.
