Domain Forwarding

Domain forwarding allows you to easily send mail through one server to another. This will allow your server to act as an incoming gateway to your network, and permit you to have a single point of entry for incoming SMTP traffic. For more information about the roles of Domain Forwarding, please see Gateways and Other Server Roles.

When messages come in to a forwarded domain, they are run through the command-line exe referenced in Protocol Settings. If a delivery delay has been established for the server, messages are also delayed accordingly. This allows you to establish an incoming server that can run external virus or spam scanners, which can reduce the load on your existing network servers.

To establish domain forwarding, go to the Settings -> Domain Forwarding menu and choose to add a target server. Enter the server that should receive the mail and add the domains that should be forwarded to it, one per line.

Note: If you do not host any actual domains on the server, in order for your mail server to listen for traffic, you need to set up a dummy domain ( to listen on the IP and ports from which you expect traffic.
