spamassassin

I have set-up Postfix with Spamassassin on Ubuntu 12.04.5. Fundamental usage of Postfix is to (pipe) trigger a PHP file. Till here I've arrived successfully.

Now, to avoid unneccessary load on the server, and also to avoid unwanted mails triggering my PHP script, I want to configure Postfix to allow mails only from [email protected] and reject everything else.

How to achieve this absolute lock-down on mail server unless mail comes from [email protected]?
