Mail Routing using pipe in Exim

问题

I was looking for sending email to multiple destinations i.e One to the user specified email address and other to a php script. Surfing over the web, I concluded that I have to use pipe in routers and transfer configurations of my mailing agent i.e Exim in my case. I tried but failed to embed pipe transfer in my Exim configurations. Server results in failing pipe transfer. Need help in getting this issue fixed. I modified my exim.cnf file as:

############ ROUTERS
system_aliases:
driver = accept 
domains = **.**.**.**(my Domain) 
transport = use_pipe

############ TRANSPORT
use_pipe:
debug_print = "Using Pipe Transport"
driver = pipe
command = /etc/script.php
return_path_add
delivery_date_add
envelope_to_add
return_output

where script.php is the second destination where I want to send the file. Here are the Logs:

 3402   uid=3000 gid=3000 pid=3402
 3402   auxiliary group list: 3000

 3399   ** abc@myDomain R=system_aliases T=use_pipe: Child process of use_pipe transport returned 127 (could mean unable to exec or command does not exist) from command: /etc/testScript.php

*testScript is present at the exact location specified in logs.

In routers section I wrote my own custom router that will deliver email to my desired php script. In transport section wrote my own custom transport that will ensure delivery to the desired script using curl. Kept the system_aliases section in Routers configuration as it is but changed driver from accept to redirect.Wrote the following configurations in my /etc/exim.cnf file:

############ROUTERS
runscript:
        driver = accept
        transport = run_script
        unseen
        no_expn
        no_verify
############TRANSPORT
run_script:
     debug_print = "T: run_script for $local_part@$domain"
     driver = pipe
     command = /home/bin/curl http://my.domain.com/mailTest.php --data-urlencode $original_local_part@$original_domain

mailTest.php was my php script
