#### Configuring Custom Field

Once you have set up a server, you will need to set up the one custom field. To do so, log into your Clientexec Admin Area and navigate to **Settings > Products > Custom Fields** > **Add Custom Field**.

Setup one custom field:

###### Email Domain:

**Field Name**: The name you set for the Email Domain Custom Field while setting up the server.
**Field Type**: Text Field
**Is Required**: Yes
**Include in Signup**: Yes

If you have not already done so, go back and add this to your Server settings.

#### Creating Products

Navigate to **Settings > Products > Products**.

Create a new Product Group for your Email Servers, and make sure the type is Hosting. Add the custom field you created to the product group.

Create a new product under your product group to sell Email Accounts, and make sure you tick **Hide hosting custom fields**.

You can set up the pricing terms that you want to offer.

Once you save changes, navigate to the **Advanced & Plugin Settings** tab and select your OpenSRS Email server and save.
