Defining a “messagle handler” in Postfix

Question

We are using Postfix for mail delivery and I am trying to make a shell script handle an email sent to foo-bar-baz-bat@example.org.

Is there a way to do this and how?

Postfix's Before-Queue Content Filter can help:

I wrote a post about how you can use it but you can easily adapt it to your needs:
