Run php using a pipe in Postfix.

Thank you for your help.

I set up the settings to run php using a pipe in Postfix.
Is there anything missing?
Professor, please
(I set it up in a different environment and it worked.)

Environment
Linux CentOS 6.6
Postfix 2.6.6

1.
Add program start pipe processing to master.cf.
For your information, I did the following

webmaster-test unix-n-pipe
  flags = User = vmailuser argv = /usr/bin/php-f/tmp/test.php$sender

2.
Add the email address that transport passes to the pipe.

webmaster@***.com webmaster-test

If I send an email to webmaster@***.com, /tmp/test.php will run, but it won't.
