Introduction

Procmail is a very powerful program used to filter emails. With it, you can redirect your mail, sort it, or even protect yourself against spam.

To give instructions to procmail, you need to create a file named .procmailrc in your home directory.

Installation and configuration

To install procmail, as usual:

  apt-get install procmail

Then, for documentation, I recommend the following: Procmail Documentation

Follow that with my small example and you should be able to do what you want :-)
