Hi
Yes, WinGate can operate as a secondary. Basically for the domains you want the WinGate to be secondary for, you create a domain in WinGate Email, specify that it is hosted on a remote server, and specify the server, entering the name of the primary. Don't select using MX, since this machine itself will presumably also be an MX server for the domain.
Then if anyone delivers mail to that WinGate for that domain, it will be queued for delivery to the primary server, and retry if it is currently unavailable. Benefits here are that you can get this WinGate to authenticate to the primary if you need it to be trusted.
Be aware however that many spam agents deliberately try to deliver to secondary servers, in the (well founded) belief that they are more likely to be less securely configured, or have a less up-to-date knowledge of valid users etc.
