Part of what makes core.async great is that you don't have to use atoms to communicate between threads in every case. For your case, I don't see what using an atom gets you. It seems like you could replace the atom with a channel, and put values on the channel whenever mail is sent. Your code will be almost unchanged, except you'd replace your atom reset with a channel put.
