need help reverse-proxy config

[Thierry]

Thx a lot ... I do understand  better now.

In my nginx.conf I do have:

*****
stream {
  limit_conn_zone $binary_remote_addr zone=straddr:10m;

  upstream backendmail {
    server email.domain.tld:448;
  }
}

*****

In my server.conf  I do have:

*****
server {
    listen 448 ssl;
    error_log   /var/log/nginx/error-proxy_mail.log debug;
    ssl on;
    ssl_certificate /etc/ssl/certs/cert.org.chained.crt;
    ssl_certificate_key /etc/ssl/private/iRedMail.key;
    include /etc/nginx/sslciphers.conf;
    ssl_session_timeout   60m;
    ssl_handshake_timeout 10s;
    proxy_connect_timeout 10s;
    proxy_timeout 300s;
    proxy_pass backendmail;
    limit_conn           straddr 15;
    limit_conn_log_level error;
  }

******
When tying to  run  the server:

nginx: [emerg] "ssl_handshake_timeout" directive is not allowed

If removing  this directive :

nginx: [emerg] "proxy_timeout" directive is not allowed here

etc ...

I did  respect the context this time.

Thx
