BellSouth Email setup on Android is easy, but it can't be possible without knowing the right server details. What you should do is navigate through the Accounts& Sync option from the Settings of your Android device. Then, add an account of yours with BellSouth email settings, including incoming and outgoing server details. By doing so carefully, you can easily set up your account on the device you want.
