Enhanced-mailgate & rt3

My company is in need of the functionality of enhanced-mailgate, but
with rt3. Has work already begun to update it to work with rt3? If
so, where can that be found? If not, would it be recommended for us to
start fresh with a new implementation for rt3, or work to port
enhanced-mailgate?

Thanks,
Ben
