email forwarding: pipe to a program

Ever tried to read your mail outside of your mail client?
Then here's your chance to try to read or play with your incoming mails.

go to your cpanel , look for email forwarding option.
Add a new email forwarder and from the drop down list choose "pipe to a program".
In the text box enter a pipe sign `|` followed by a path to your script file.
eg.
|/home/mysite/public_html/test.php


Set it permission to 0755 and put a hash bang as the very first line of your code


In your test.php (or another) structure your code as this:


#!usr/local/bin/php -q


   --- your php code goes here---
//To read mail use this : 

$fd = fopen("php://stdin", "r"); 

#end
