Hello !I have a 2-nodes-active/passive cluster, each node runs postfix independently, only for local email.
I would like to achieve this scenario:-if the nodes are both secondary, or one is down and the other one is secondary, each node stores locally iits own emails.
-If a node `is or becomes primary`, the secondary node transfers its own emails to the primary node.
Could you give me some clues ? Regards, Vianney
