How to change Received (Proxmox)

[Mersa]

Hi,

How can I change the text in the source (Proxmox) of the e-mails received by PMG?

Example content;
Received: from ....... (Proxmox) with ESMTP id 5007461133

 

[poetry]

This should be your server hostname

You can edit the file /etc/hostname

example
nano /etc/hostname

edit the file to match your needs (it should look something like this mx.example.com or mail.example.com)
save the changes by using ctrl +x and Y

You can also change your SMTPD Banner via Configuration - Mail Proxy - Options - SMTPD Banner (it should usually be the same as your server hostname)

After the changes restart and test again. Make sure you have also configured your PTR records for your server IP you can check via https://mxtoolbox.com/ReverseLookup.aspx and https://mxtoolbox.com/diagnostic.aspx to check if your server is configured correctly.

Hi,

What I am asking is not smtpd banner or hostname or rdns record. I want to change the (Proxmox) with ESMTP text in the Header in the source of the e-mails.

My mistake I am guessing it's this
nano +56 /var/lib/pmg/templates/main.cf.in
mail_name = Proxmox

Follow the template recommendations https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine to retain this value after upgrades.

example:
cp /var/lib/pmg/templates/main.cf.in /etc/pmg/templates/main.cf.in
nano +56 /etc/pmg/templates/main.cf.in
change the value mail_name = Proxmox and save changes then
pmgconfig sync --restart 1
