Shell Scripts in Postfix

Hi people! I have my system in an internal email using Postfix. I saw this way of implementing a filter. However, I am trying script 1 #!/bin/sh 2 3 # Simple shell-based filter. It is meant to be invoked as follows: 4 # /path/to/script -f sender recipients... 5 6 # Localize these. The

I think if there is a hook that i coul
