Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

We have just about everything we want, with one exception- I have no way to easily add an IP address (or range) or domain to manually blacklist.
Yes, you can do it with complex tables and hashes that have to be rebuilt every time you want to add or change something in it. But isn't there a way I can have either Postfix or Postgrey just look in a plain text file for a list of banned IP's/names without having to rebuild a hash table every time (and sometimes even reloading Postfix)?
Then make sure you have "check_client_access hash:/etc/postfix/client_access" in your "smtpd_client_restrictions" section (or any section) in /etc/postfix/main.cf.
All you need to do is type "addblacklistedip x.x.x.x" and hit enter. In fact, you can name the script anything you want. "blacklist" "badip" etc. It will append the IP with REJECT in your client_access file and postmap it. This will stop the IP from connecting to Postfix.
