Postfix on another server not on PVE

[horizn]

Hi,
Is it possible/safe to diable Postfix from autostart and use Postfix configured on another server?

Hi,

you should add the relay server in the postfix conf and do not disable postfix.

Not good. Currently I have only one public IP, and the plan is to have VM running mail server with ports (465, 587, 993, 995) forwarded on to that VM. So ideally will be to shutdown Postfix on hypervisor.

Proxmox VE uses sendmail for notification and the pve-manager has a dependency on it.

But it should still work if I change smtpd port in Postfix on Proxmox?

You could let postfix run and bind only to localhost :1/127.0.0.1) - if you plan on forwarding the ports via iptables this should work.
