Reciting durood when hearing the blessed name of Rasulullah (Sallallahu Alayhi Wasallam)

I had heard that whosoever does not send durood on the prophet (Sallallahu Alayhi Wasallam) when they hear the prophets name, they are cursed by Jibrel and Ameen was said by the prophet (Sallallahu Alayhi Wasallam). Is it correct? Now if its is, then what are the rulings if we hear the name of prophet in namaz (Salah) from other people? And while listening to Qur'an in Salah And what if we were reciting Quran and we heard the name of the prophet? Could you please tell me.
