Exim4 maybe a heavy weight e-mail system, but the package config can make it very simple to set up your server to forward all received mail on to you main e-mail server.

A friend of mine had two drives fail simultaneously in his RAID setup. Since those were the only two, he faces serious data loss. (everything since the last backup, and yes, he did have one of those). He tells me that when he investigated he found that one of the drives had failed silently some time earlier, and the RAID was covering for the failed drive by using the other. He also told me the SMART stuff had provided no indication of any trouble. I find myself wondering just how he found out that his drive had been nonfunctional for some time if he didn't have any diagnostic information -- but this story is enough to make me suspicious of RAID monitoring tools. Should I ask further about *exactly* what he had set up abd report back here?

Not all RAID controllers will provide SMART info from the drives, so using SMART status to check your array health is a very bad idea. The only sure way to know when a drive in an array fails is to monitor the array itself via appropriate tools. Should I ask further about *exactly* what he had set up abd report back here? (by the way, it wasn't Debian, nor was it and AMD-64, so this is technically off-topic.) My guess would be that, as I said above, he had some SMART monitoring tools going, but no RAID monitoring tools. He just had log entries from the RAID kernel driver telling him that a drive had failed, and probably wasn't checking his logs regularly enough.

I would also like to use a easy to setup/simple to use mail service for this. I've looked at Nagios for the Monitoring and it looks like hitting an ant with a bazooka.

Right, I've got Smartmontools installed and working just fine, as well mdadm working for my array. Can these tools be configured to send alerts to a local mail account???
