<html> I made a monitor from my machine (CentOS 4.5) to do an http to a machine retrieve some info to see if a process is running (on this remote machine I have a task running so it is easy to get the info from my machine). If I cannot access the remote machine, my machine sends mail to me and a couple other people saying the machine is unreachable. My cronjob runs every 5 minutes. Juts occured to me now though that if our network goes down, my machine will be sending mail every 5 minutes saying the machine is unreachable. These messages will get stored on my machine and all get sent when it comes up. I am wondering whether someone knows how to cancel mail that is queued on a machine, so it doesn't all get sent out. I do have root access. </html>
