I hope you will be able to provide some basic guidelines on how to
enable/use the new functionality. (I am not very code-literate.)

Looking through the code, the functionality should not be too hard to enable using the configuration:

This is a list of trusted networks... ips are seperated by ", "

default, empty

haproxy_trusted_networks = 10.1.2.0/24, 10.2.1.0/24

This is the timeout... in seconds.

default, 3

haproxy_timeout = 3

modify your inet listener's to include haproxy=yes

inet_listener { haproxy = yes }

As for HAProxy, the configuration would look something like this:

listen smtp :25 mode tcp option tcplog option smtpchk balance roundrobin server smtp1 ip.of.server1:25 check-send-proxy check inter 10s send-proxy server smtp2 ip.of.server2:25 check-send-proxy check inter 10s send-proxy
