Easy integration into existing e-mail server architecture

In a default configuration, e-mail traffic arrives on the firewall and will be forwarded to the internal e-mail server. With the integrated Proxmox Mail Gateway all your e-mail traffic is analyzed and filtered before reaching your internal e-mail server. You can manage incoming and outgoing e-mail traffic.

For other deployment scenarios including Proxmox Mail Gateway HA Cluster setups please take a look into the Proxmox Mail Gateway Deployment Guide.
