Topic: loadbalance iRedMail
I was thinking about load-balance for our email server, as pr today we are running only one mail server, but I will have 2 mail servers instead.
so one of the options is to setup a new server and configure MX record pri 20 for example because MX priority 10 is used for primary server.
But the question now is if the primary server fails and secondary is up and running for example 5 days what happen with emails which users received in their inbox when the primary server is coming up again ? how is this handled ?
Or is there a better way to load-balance it ? what I am looking for is, we can run only one server but if that server fails than secondary server should take over... But the problem is how can we synchronize the users inbox later ?
any good suggestions ?
