Mavericks server alerts and User account questions

Question

Hi
I'm looking for more detailed information about setting up Alerts in Mavericks Server, plus I seem to have a strange problem with new user accounts when setting up.
More Info.
I have a Mac Mini acting almost 100% exclusively as a Time Machine backup device with encryption of three portable computers on a wired network.  This was originally set up three years using Snow Leopard Server and a 2Tb external FireWire Drive.
The external drive is now proving too small, and in any case is showing the possible first signs of failure when tested, so the intention is to replace it with a RAID of some sort, probably a 2-drive RAID 1 device but if the budget allows we might be able to look at RAID 5 or 6 units.
It seems a good opportunity to clean install Mavericks Server on the Mini, so I've set up a test station on my MacBook Pro with my Mac Pro (both running 10.9.2) as a test backup client.  The Server OS is on an external FireWire boot drive, and the TM backup folders are on another external, in this case a USB 3.0
For obvious reasons there does not seem to be any reason to turn on more services than absolutely necessary, so just Time Machine and File Sharing for the moment.  All works well but I can't seem to get Alerts working.  I've listed 3 different eMail addresses (all mine) for the alerts to be sent to, and I have two Admin Accounts for Notifications, both using the same AppleID I set the Server software up with.  I've gone through the rather sparse setup help information carefully, and there is no information about additional services being required, although I did try setting up the Mail client (tested sending and receiving) on the Server and having it running whilst the backups were being tested.
As I said, the test backups went fine and when I disconnected the backup drive from the Server to simulate a failed drive the TM on the Mac Pro client showed an alert saying the backup drive could not be found.  However, there were no emails or Notifications received, either on the Mac Pro or my iPhone from the Server.
There seems to be minimal amount of information available about the workings of Mavericks Server, but I have gone through what I can additionally find online about Mountain Lion Server, with no real indication of what it is that I am missing.  The only instructions seem to be exactly what I've done, so your advice would be appreciated.
Another thing that puzzles me, is that when restarting the MacBook Pro I get all the Admin and Standard User Accounts (created in Server.app) showing at the login screen.  This is only four Accounts in total, so what would happen if this was 50 Users?  If I click on the 'User' tab in Server.app I get 83 User Accounts showing, but that was not the case until this evening, as only the Admin and Stardard User Accounts I had set up were visible.
It's obviously possible that I've mucked up the install and basic setup somehow, but I can't see that anything I've done would have these effects as I've been careful to follow the options put in front of me.
Thank you in advance.

There's nothing to fetch. You assign the value from the function GET_APPLICATION_PROPERTY(USERNAME); as you would any value returned from a function.
DECLARE
   myVar    VARCHAR2(50);
BEGIN
   myVar := GET_APPLICATION_PROPERTY(USERNAME);
END;Hope this helps.
