Hi dcsapak,
I for one would want to have different settings fro the mail servers, since for me the gateways are in different locations, however the incoming e-mail, and quarantine should all be the same if possible (all going to the "master").
In my example:
Site A:
Primary Proxmox Mail Gateway
E-mail Server
Services sending e-mail via the mail gateway as outgoing
Site B:
Secondary Proxmox mail gateway
Services sending e-mail via the mail gateway as outgoing
However both site A and B have only 1 public IP and thus I want to deliver the mails from site B via a seconcdary port towards the e-mail server, and not send again to the primary mailserver. And since there is no site-to-site VPN I also can't use the same IP address.
So what I would like to see to have the same settings are:
accepted domains;
Quarantine
Logs
Seperated I would like to see:
Smart host
per domain endpoint
Note, I know some biger comapnies who have the same kinds of prodcuts do this by default.
