(There are no backend servers configured in nginx, for mail.)

Correct.

auth_http is documented at http://nginx.org/r/auth_http, which also
shows the authentication protocol.

nginx does not care how the authentication is done, or how the ip:port
to next connect to is chosen; it just connects to what it is told to by
the response of the auth_http request that it makes.
