I'm trying to figure out how email event handling functions.

I want Mango to send me email when user logs in. And it works.
I configure it in Event handlers/System events/User login.

Where is the code that is activated when user logs in? That code should check what event handlers are configured and send email.

Of course, it's not all code in one file, but can you tell me where to start?

Thank you very much
