In Snow Leopard Server, under Workgroup Manager, I used to be able to forward mail to that account to another email address. I no longer see that option. Did they remove this ability or am I missing something?
Lion Server (just like Leopard Server) uses postfix as its outgoing mail server. Unfortunately your not missing anything. Apple did remove the GUI way of forwarding email. You can still accomplish the same thing editing a couple of configuration files and running a few command in Terminal.
