For those who might need this later, I've finally with the help of gandi-hosting newsgroup / irc Found solution to my problems :
1rst thing : My transport_map was not initialized in main.cf : To make piping work it's better to set it correctly without any misspelling... transport_maps = hash:/etc/postfix/transport_maps which contains : bounces.f.net bounceh: 2nd thing : Master.cf had a problem with php file mapping, I had followed : http://answers.google.com/answers/threadview?id=562518 In my case I had to use following : bounceh unix - n n - - pipe flags=Rq user=phpuser argv=/usr/bin/php /srv/f/www/f.net/htdocs/bounces/get_bounces.php $sender $recipient Last thing : Php script must take a #!/usr/bin/php in first line to make it bash comprehensible... don't know why but seems needed. Script must evidently have rights to execute. Php script must be unix formatted, beware of any Windows / Mac editors that can loose the unix format to file and throw errors like file not found, when the file does exist with a ls -la. Thanks any case for your ideas... T. de LASSAT
