I have been trying to get a reliable email app for both my wife and myself. We have Comcast accounts. We are both new Moto Driod users. We aren't big into Gmail and the default email app is doing different things on our individual devices. Mine is randomly deleting emails ( I think). At least they are leaving the inbox without any input from me. My wife's gets mail sometimes and then won't get anything for days. Anyway I am trying out K-9 Mail and it seems to meet our basic needs. My problem is that I don't seem to have turned off the default email account. I did delete it from the accounts and sync screen in settings. So now I get two buckets of incoming mail. How do I turn off the default email accounts, to include gmail, so that I only see what I am getting from K-9?
