Pipe works, but return delivery message to sender


Recommended Posts

Hi sirs,

I have WHMCS work perfectly, but I have a problem with pipe mail.

When a customer send a email to any support department adress (eg. support@mydomain.com), the ticket is opened, but customers receive two return messages, one confirmation of ticket opened and another, a return delivery message as bellow:


Subject: Mail delivery failed: returning message to sender‏


This message was created automatically by mail delivery software.

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/user/public_html/customers/pipe/pipe.php
   generated by support@mydomain.com

The following text was generated during the delivery attempt:

------ pipe to |/home/user/public_html/customers/pipe/pipe.php
      generated by support@mydomain.com ------

------ This is a copy of the message, including all the headers. ------

Return-path: <sender@domain.com>
Received: from localhost ([] helo=hostname.server.com)
by hostname.server.com with esmtp (Exim 4.69)
(envelope-from <sender@domain.com>)


I searched around internet, and found similar problems, but show specific erro. In my case, you can see, that dont show erro. Only a blank line between this line:


------ pipe to |/home/user/public_html/customers/pipe/pipe.php
      generated by support@mydomain.com ------

------ This is a copy of the message, including all the headers. ------


I think the file pipe.php is generating return output as blank line.

I check the file, and dont have blank lines.


The file have chmod 755 and the forward have this value:

support@mydomain.com: "|/home/user/public_html/customers/pipe/pipe.php"



Somebody can help me?

I'm having the exact same issue. I submitted a ticket about it, and they told me to do the obvious (CHMOD, try different command variations, etc), but I still haven't been able to correct it. They haven't replied since I told them I already tried everything, but hopefully I will hear back from them soon.
