Outbound relay configuration

Jan 18, 2020

We are new to Proxmox Gateway and we have set up a Proxmox gateway and we are trying to set up an outbound relay from Postfix through PMG.

Can anyone advise on the correct configuration we have to change in postfix for the outbound to work?

Thank You
In postfix, you just set the smarthost to be:


where pmg-server.example.com is your PMG server address and :26 is the Internal SMTP port set under Mail proxying -> Ports . With that said, any mail going out from your postfix server will go through PMG and then PMG will send it off if it is clean.


The Proxmox community has been around for many years and offers help and support for Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway.
We think our community is one of the best thanks to people like you!
