No.

Usual aproach is to configure http in the same nginx and 
proxy_pass/fastcgi_pass/whatever with appropriate balancing and 
redundancy, e.g.

mail {
    auth_http 127.0.0.1:8080/mailauth;
}

http {
    upstream auth-backends {
        server ...
        server ...
    }

    server {
        listen 127.0.0.1:8080;

        location = /mailauth {
            proxy_pass http://auth-backends;
        }
    }
}
