I'm actually receiving NOTIFICATIONS of mail that I SEND now. Is this something to do with iOS8.4 because it wasn't happening previously? Very odd and would love to not have that, as I obviously know I sent the message.
Yes, exactly. It's really strange and I have no idea why it's happening. I don't CC or BCC myself on any of the messages, either. And the devices, except my MacBook Pro, receive them now. Apple Watch AND iPhone.
