VPN, or RPC over HTTP (which works with E2003 and OL2003 on WinXP SP1/SP2
only).

Don't just open ports. Seriously. Also, I do not recommend that you have
your Exchange server in a DMZ....you're defeating the purpose of a DMZ by
doing this. Stick the server behind the firewall and control access to it
therein.
