Yeah - sendmail is set to listen to local host only on a default setup. Change in sendmail.cf O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA To.. O DaemonPortOptions=Port=smtp,Addr=0.0.0.0, Name=MTA However I don't know what this does security wise, and whether this will open it up to relaying - so be warned.
If the config is sensible (and I think the default one is), then this shouldn't allow relaying, but I'd still recommend that you restrict port 25 access to your local network (assuming you dont need inbound smtp access). O DaemonPortOptions=Port=smtp,Addr=192.168.1.0, Name=MTA looks sensible (assuming you're running a 192.168.1.0/24 netblock). Although firewalling everything you don't explicitly want is always a good bet.
