Cluster, Load Balancing mail system with HAProxy

[bzero]

Hello,

Is that possible to deploy clustering mail server system? My idea is as below

HAProy --> (Poste 1 and Poste 2)

With postfix, i can use this option: postscreen_upstream_proxy_protocol =haproxy And dovecot, https://wiki2.dovecot.org/HAProxy

Not sure if Poste can support this. Please advice.

Thank you.

Hello,

since "whole-in-one" poste mailserver is consisted of lot of moving parts which are not prepared to behave as synchronizable master-master it is almost impossible to do it right now without huge amount of work...
