The Help Desk solution integrated with Plesk provides the server administrator with an easy-to-use interface for handling technical assistance requests submitted by the control panel users.
Before users are able to submit the trouble tickets, you should perform an initial configuration of Help Desk. To this effect, you should create at least one instance of Queue, Priority and Category and then activate the Help Desk:

Queues icon. The page opens displaying the queues registered in the system:

Select the
Add New Queue icon. The queue properties page appears:

Enter a title, select the Enabled checkbox and click OK.
In the same manner create at least one Priority and one Category using respective
Priorities and
Categories icons on the main Help Desk System’s page.
Once the queue, priority and category are created, return to the main Help Desk page and click
General Settings. The General Settings page opens:

Select the "Allow customers to submit tickets" checkbox, and select the default queue, priority and category, created at the previous steps. Click the
Enable icon. Help Desk is now activated. Click OK.
You can also allow submitting tickets by e-mail. To do this you need to configure the mail gate:

Mail Gate Settings icon. The mail gate configuration page opens:

Fill out the following fields:
Once the required fields are filled out, click
