No push notification on iOS Mail app
I've seen other posts here that push on iOS native Mail app works but I haven't been successful. I can send and receive email from my mailbox.org email and alias using the app. However it is only after I open the iOS Mail app does the message show up in the inbox. I have set the account to use "push" in iOS. What else do I need to do to get iOS Mail to receive pushed emails and provide a notification?
