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

Note that all "#{dzSomething}" notations are tags. So in a running system they should all contain valid configuration instead.

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):
