Windows Svr 2K3: which ports should I open for exchange 2K3?

We have an exchange 2003 server that I'd like to use the built in server 2003 windows firewall, but which ports should I open to get this going? So far, I'm not comfortable having the windows firewall turned off on that server...

Thanks!

None. Put it behind a real firewall or your asking for a LOT of trouble. Despite that, this link will help you a bunch: http://support.microsoft.com/?kbid=278339

nm....each year, I get inspired and decides to lock down exchange. However, I get disappointed everytime,, because I realize with those ports opened...you're already giving away the whole world...

sigh!
