Do I need to keep the Mail app open and/or running in background for it to work? I did all the updates and my MBPR says in power save that it'll check for messages in powernap, but nothing gets downloaded.
I left my mac in sleep mode, came back 3 hours later and checked email. All my emails came in. Nothing was downloaded while it was sleeping.
