Question

About a year ago someone helped me to setup a file that would pipe email coming to a specific domain to a PHP script. I am on UNIX (CentOS) and know that the file should be in /etc/aliases

Have no idea what else to look for. I need to modify the file to add similar functionality for another domain.

Any guidance would be highly appreciated.

For postfix:

VERY IMPORTANT: Save existing /etc/postfix/master.cf and /etc/postfix/transport.

Edit /etc/postfix/master.cf

Append these line

php-transport    unix  -       n       n       -        1      pipe
    flags=Rq user=phtran argv=/path/to/script.php ${sender} ${recipient}

Note: it’s important to have white space before flags
For more parameters to pipe read this -> http://www.postfix.org/pipe.8.html

Create user phtran and assign it to be the owner of /path/to/script.php. Make the script executable.

Add this line to /etc/postfix/transport

my.domain php-transport:
.my.domain php-transport:

Run

postmap /etc/postfix/transport

Here is the doc for tarnsport map: http://www.postfix.org/transport.5.html

Restart postfix service.
