Flashed in Spain… ..and now?

Hello, I was flashed last week in Spain (near Barcelona) from behind. I didn’t drive much faster (out of town, about 15 kmh faster than allowed), but as far as I know, the speed cameras there are quite “sensitive”. What now? Do I get mail from Madrid now? Or does it get lost somewhere in the EU-Burocracy chaos? thank you for your help! best greetings, Fabio PD: I haven’t seen a “right-jura forum”, so I’m posting it here in “Transport & Security”.
