I've set up osticket in an ibay called support, which from a web point of view, works fine. I can post how I did it if interested, but I do run signal-event ibay-modify support at the end to make sure the permissions are set up right.
The package does have a pipe.php which should accept emails and parse them into new tickets.
I created a /var/qmail/aliases/.qmail-support, which contains:
|/home/e-smith/files/ibays/support/html/api/pipe.php
When I send mail from an external host to support@... I get relaying denied
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:

Technical details of permanent failure:

What am I missing?
