Using bogofilter via KMail's anti-spam wizrd

[Maurice]

Here on Linux Mageia-5 - after being suddenly being swamped with junk
emails - I've installed bogofilter* and used KMail's Anti-Spam Wizard to 
hook up with it to set up junk filtering.

The Anti-Spam Wizard found bogofilter and added Spam and Ham icons in 
the toolbar, which I've been using them to select the emails for 
bogofilter's training.

I assume it wll take some days/weeks(?) before its learning process 
will allow it to start zapping junk emails for me.

The $64 question is: 
   What indication should there be when eventually it identifies a spam 
email and automatically moves it into its 'spam' directory, without my 
having to hit the Spam icon?

Does it move it silently, or wave some kind of flag or play a happy 
tune?
