Hi,
I configured haproxy 2.1 with postfix using the sample socket configuration found in example folder, socks4.cfg.

I managed to send mail. but it takes around 30 sec average to get a success response.

I observed that I get response near to same time when I get email. Is it working in a synchronous way. But If I call direct to one of the SMTP then it give me immediate response.

So how can I configure it in a asyn way to get immediate response

Thanks
