Reading through this post to understand how the piping works and how to setup it properly, I came across this post. It appears that this post is referring to setting up piping using a primary domain email with WHMCS installed on a sub-domain.
For example:
Domain: somedomain.com
Pipe Email:
[email protected]
WHMCS: subdomain.somedomain.com
There are many ways listed here to set it up so I figured I would add the way I got mine working without the extra email accounts and forwarding. I do not know if this will work for everybody, but I did it without the extra forward to a
[email protected]
I used the directions found here:
http://wiki.whmcs.com/Email_Piping
My subdomains I create will work with either of the following addresses:
http://subdomain.somedomain.com
http://www.somedomain.com/subdomain
I use C-Panel (X3) and created a forward from
[email protected] using this command (found from my WHMCS Support Departments):
php -q /home/cpaneluser/public_html/subdomain/pipe/pipe.php
(original command included a "|" in front of php but cpanel forwarders would not accept it)
Replace the "cpaneluser" with your cPanel Username and replacing "subdomain" with the folder you actually used to install WHMCS.
I have tested it both ways: from user and admin, and the piping is working perfectly!
NOTE: Even though I am using X3 theme in C-Panel, using only "public_html/subdomain/pipe/pipe.php"
DID NOT work. Even though the Trace in Cpanel resolved, it would not pipe through. It started working by changing the command for piping.
Hope this helps someone along the way!
