Currently running exchange server on one physical server (yes, I know this isn't best practices... I'm getting a copy of SBS and will eventually run ISA but for now, I'm just happy things work). This is not (yet) a critical server-- it's mostly for hobby, but will soon be serving emails for a small (3-5 person) firm.

What ports on the firewall are *absolutly* necessary for exchange in this configuration? I'm running rpc/https, owa, and mobile outlook. I'm using exchange 2003 standard, running on top of server 2003 enterprise.

Port 443 (HTTPS on SSL)
Port 25 (SMTP)

No other ports are required.
