I have several att.net email accounts that I have set up on my Droid4 without problem except that "push" does not work with them. If I set them up as Yahoo accounts, but manually enter all the info, it sets them up fine and email is pushed, but when I delete an email on the phone, it deletes it on the server. There doesn't seem to be a way to change a setting so that the emails are not deleted. Can anyone help?
