Proxmox mail gateway

powersupport · Jul 4, 2023

Hi,

Is it possible to setup a Proxmox mail gateway to send emails via different IPs ?, I mean shuffle the IPs according to server load.

Thank you

Out of the box - no

however you can probably adapt the postfix configuration using the templating system:

see this old thread for some ideas:
https://forum.proxmox.com/threads/postfix-mail-rotate-outgoing.53584/

keep in mind that this is not a supported or tested setup - so some things might not work as they do without modifications

I hope this helps!
