>Applications such as Apache or a cron daemon often need to send mail to users (often the root user) to 
>inform them of an error or simple operations. When a system is not properly configured to relay these
>emails some problems may arise which might not get noticed. For example, a job is set up in a cron daemon 
>that outputs some sort of message. What the cron will do (by default) is send an email to
>root@localhost. However, because root@localhost is not a real email address, the email will be sent out
>to no one knows where and bounce. The bounced email will most likely make its way to your ISP's servers 
>(or other email servers on its way). This mini-guide explains how to configure your machine to make such 
>emails come to you rather than strangers.
