I am running Postfix mail on ubuntu 14.04.1.
I want to "trigger a PHP script when Postfix server receives a mail" After investigation and the help of many tuto, . I have configured "postfix" & "Postfix virtual Aliases" first time (I don't have deep knowledge of it) and I wrote my php code but the script output is always empty. Below all necessary file that allow you to detect my error.

Is this the correct way to " Trigger a PHP script when your Postfix server receives a mail " ?
If Yes , can you help me to run my script else any advice to find another way.
Best Answer
Do a tail -f on maillog, pipe it into your program and look for delivered statements. Then, you'll not be interfering with the system's spam filtering, and will only get solid hits. You'll also know who received the message - it's in the log file...
As for php, well, it's the wrong language for this, but your watching program can launch php to do whatever is needed there. Someone who's really clever might even be able to figure out how to harness php to do this, but, again, wouldn't be my choice.
Trying to catch mails through the mechanism you propose isn't likely to ever be made workable.
