Running on OS X Server?

Is there a method to run SpamSieve as a service on OS X Server, and process mail as a drone without having to leave a user session logged in?

Or is it dependent on a desktop mail client open and running. I use MailMate on desktops, and Mail.app is available on the server if needed.

I know OS X Server has mail server and spam filters built in, but for simplicity a SpamSieve option would be nice to have.

No, that’s not currently possible.
