Remove Proxmox hint in header of sent mail

[Afox]

Hello,

in my header I have something like this:

Received: from mail-gateway-domain.tld (localhost [127.0.0.1])
by mail-gateway-domain.tld (Proxmox) with ESMTP id #############
for <recipient@mailaddress.tld>; Mon, 24 Jun 2019 10:00:00 +0200 (CEST)

How do I remove that Proxmox hint please?

Regards,

Afox

This should be the 'mail_name' setting in postfix' 'main.cf'
To change that please follow the reference-documentation: https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_service_configuration_templates

Hi Stoiko,

This should be the 'mail_name' setting in postfix' 'main.cf'

When using the templates, do we need to carry the entire template across to update a single variable?

ie. Could we just specify the variable in need of override in /etc/pmg/templates/x.y or does the entire template need to be brought over?

yes - you need to copy the whole template and adapt it.

If the template in the package changes you will be asked and warned that a new template is present - via ucf(1)

I hope this helps!

Is it possible to hide somehow entire:

"Received: from mail-gateway-domain.tld (localhost [127.0.0.1])
by mail-gateway-domain.tld (Proxmox) with ESMTP id #############
for <recipient@mailaddress.tld>; Mon, 24 Jun 2019 10:00:00 +0200 (CEST)"

header?

no that last part is not (sensibly) removable:
you can enable hide internal hosts in the Mail Proxy Options - then for all mail received on the internal port everything before that line will be removed (thus obscuring your internal network)
This last header is added by postfix on the way out of PMG - and is needed to prevent mail-loops

I hope this explain it.

Thank you.
Yes, my goal is to hide my internal host names from header and even "Hide Internal Hosts" is enabled but last header still exists. I beleive this header is needed because of ESMTP id, so is it possible at least to hide local domains or change it?
