We plan on deploying a few iRedMail Enterprise Edition servers, and want to configure them in HA with our Proxmox infrastructure. I've been asked to verify / get clarification. For each iRedMail server we have that is configured for HA, can we maintain one license per node? Do we need to have two EE licenses for a replicated host?

Additionally, is there anything I should be aware of for HA configurations for iRedMail? All replication and configurations will be handled by Proxmox, but if there's anything in the configs we should have in place on the actual iRedMail server itself, please let me know.
