<?xml version="1.0" encoding="UTF-8"?>
<provisioningDescription xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<packageExtension name="MailAddon" xdt:Transform="Insert">
        <serviceLimitationList>

- On the Billing box: You have to change C:\Program Files (x86)\Atomia\BillingAPIs\BillingApi\Web.config,

(This should be done trough transformation file:

EDIT file "C:\Program Files (x86)\Atomia\BillingAPIs\BillingApi\Transformation Files\Web.examplenet.config")

FIND line <provisioningOrder provisioningService="MSSQLAddon" order="10" />

- ADD bellow it:

<provisioningOrder provisioningService="MailAddon" order="10" />

- FIND line <!-- Extensions -->

- ADD bellow it 

<package name="MailAddon" type="PackageExtension"> <!--package name-->
      <properties>
              <packageProperty key="MailAccount" /> <!--name of service to extend-->
       </properties>
</package>

- so at the end section looks like

<!-- Extensions -->

 <package name="MailAddon" type="PackageExtension">  

            <properties>

              <packageProperty key="MailAccount" />

            </properties>

         </package>

         <package name="StatisticAddon" type="PackageExtension">

         </package>
