Add mailFrom (sender) option to mails

Why

If this isn't done, then reset password messages (and in the future, all messages) will say that they are coming from a default email address at Digizuite (hostmaster@digizuite.com).

1. On your web server, navigate to C:\Program Files\Digizuite\UserManagementServices\[yoursite]
2. Edit the file named Digizuite.UserManagement.MessageHost.exe.config

3. In user management service config, notice the following section:

   <messageHost>
   	<endpoint endpointName="#{dzMessageHostEndpoint}" concurrencyLimit="#{dzMessageHostConcurrencyLimit}" />
   </messageHost>

4. It's missing an element for the notification - it should look like this:

   <messageHost>
   	<endpoint endpointName="#{dzMessageHostEndpoint}" concurrencyLimit="#{dzMessageHostConcurrencyLimit}" />
   	<notification mailFrom="#{dzMessageHostMailFrom}" />
   </messageHost>

   ^-- Where #{dzMessageHostMailFrom} should be your chosen sender email address

Here's the Jira for fixing this issue. It seems to affect all versions from (and with) 4.7.0 to (and with) 4.8.0 (at least):
