[Evolution-hackers] How notifications work?

[Cristian Vrabie <cristian vrabie gmail com>]

Hi guys!
I've been using Evolution for a long time, but only recently i decided to get look into the code and maybe give a hand with the development in the little free time i get. 
I wanted to start small issue that interested me, more exactly why in KDE, when you receive a new message, the raised notification does not properly indicate the folder where the message ended up after filtering. I created this bug https://bugzilla.gnome.org/show_bug.cgi?id=605986 which apparently is not an Evolution issue but of libindicate. In order to fully understand that, can you give me a quick high level description of how notifications are raised by Evolution transparently of the notification library of the desktop environment?
Thanks!
Cristian
