6a00d8341c562c53ef01538f8abd65970b-800wi"Whats in the box" -- David Mills Lets face it, one of your users needs to have a package installed on a system, you tend to do it for them. That is, as long as the package looks safe. Sure, your not going to install an rpm that is clearly dangerous, but as long as the package name looks reasonable and you trust the user, you might actually just go ahead an install it for them without thinking much about it. Hell, I know that I have done the exact same thing from time to time. And I have done it with an unsigned package.

RHEL6 – Common Postfix Server Roles
10736157-a-cartoon-rabbit-with-an-angry-expressionIf you are anything like me you would rather not have anything to do with Sendmail or Postfix, however unfortunately it can be required learning in some circles. That being said this is my second postfix post in what I call my "Postfix: Nasty!" series. The first one can be read here, and I will be the first to admit that its not very good. However I chock this up to the fact that I really don't know much about Postfix at all and I'm writing these posts as part of the process of figuring out how to do what with Postfix. Specifically this post outlines and defines the standard roles that a postfix server can serve. Below are three common roles and their characteristics. You should get to know each of these and how to configure them.
