When an end user send a message to the support email, he receives the confirmation reply from eticket system with the ticket number but at the same time he receives a delivery failure; this is part of the message:
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
pipe to |/home/horseand/public_html/eticket/pipe.php
Any idea why this happens?
Thank you
