Hi,
I’m using Proxmox mail gateway servers as relay for sending mails and as proxy for receiving.
I have three Proxmox mail gateway servers in front of two mailcow mail servers.
On both mail servers I have several domains. Sending mail works well.
On Proxmox mail gateway servers I have disabled all spam and AV protections, RBL’s etc.. because I want to use mailcow RSPAM.
My domains on mailcow mail server as MX using Proxmox mail gateway servers and I have problem because mail server see incoming asn IP from Proxmox mail gateway not real IP.
That make me problem. Is there exists some option to bypass that through Proxmox mail gateway.
On example, mail from gmail on mail server I see that comes from my Proxmox mail gateway IP and RSPAM see and check that IP, not real.
