"stream" directive is not allowed here in
/etc/nginx/email/balanceador.conf:1
Your mail configuration file is imported inside a mail block. That won't work.
Stream operates on the same level as an http or mail block - that is, it's not *part* of the mail{} block but instead its own stream block. You would need to import the stream function directly at /etc/nginx/nginx.conf root level and NOT as part of the mail{} block. Details on *that* are in the nginx documentation: <a href="http://nginx.org/en/docs/stream/ngx_stream_core_module.html#stream" moz-do-not-send="true">http://nginx.org/en/docs/stream/ngx_stream_core_module.html#stream</a>
Basically, you're trying to include the stream configuration at the wrong level - the stream{} block you are configuring needs to be at the nginx.conf base level and NOT as part of the mail{} block as your nginx.conf is trying to do.

<pre class="moz-quote-pre" wrap="">Hi folks,
I'm trying to do a round-robin load balancing for outgoing connections from
my MTA servers. At first I tried it as follows:
[root@proxy-lb02 email]# pwd
/etc/nginx/email
[root@proxy-lb02 email]# cat balanceador.conf
stream {

least_conn;

fail_timeout=15s;
server mta-04.srvmail.com.br:26 max_fails=2

server mta-05.srvmail.com.br:26 max_fails=2
