Uni network here has 2 /16 that are allowed to deliver at the local smarthost. So that means that the server lan can also just drop it off at the smarthost. Incoming port 25 connections from outside the LAN are blocked at the router, except if they are going to one of the mail gateways. All mailservers inside have secondary and tertiary MX records set up so tat after the connection directly from the outside to the mailserver fails a retry is done to one of the mail gateways. It is pretty complicated to set up initially, but it allows students in dorms to run mailservers if they want, without being vulnerable to any open relay problems.
