Apple Mail - Two sound everytime I receive an email
Hi, I can't understand why I always hear two notification sounds every time I receive a single email. I believe it has something to do with the fact that my account is a Gmail one, and I have both the inbox and the global one (is it called Archive in English? Sorry, can't remember at the moment), but I can't find something correlated in the preference. Can someone help me understand it? It is a bit annoying...
Thank you very much.
