Not sure whether I understand the question completely.
If you want to use more PMG for outbound relaying - just add 2 A/AAAA records for mysmtp.domain.com (if that's what you've configured as smarthost in your servers)

check the features page (the HA Cluster tab) on our homepage: https://www.proxmox.com/en/proxmox-mail-gateway/features

I hope this helps!

hello, thanks for your answer.
I've already read some information about cluster in doc but not find this config.

I will attach what i need to do ONLY for SMTP relayrelay.png

The cluster do this functions? Or i need to use records?.. and if i need to use record, which your best pratices?

Thanks

as said - loadbalancing is not built in to PMG's cluster stack - instead use DNS round robin, which usually works very well for SMTP
