Hey, I'm going to set up a firewall on my Exchange server. Can somebody give me the list of ports that I should keep open, please!

It depends. All that we know now is that you have an Exchange Server. We don't know anything about what types of mail systems, WAN structuring, etc... In general, if mail is pointed to your computer via an MX record, you just leave port 25 open (smtp) and possibly 110 (for POP mail). Other than that, since we know nothing, that will get you started. If you have front end and back end Exchange Servers or Exchange Servers on the WAN side those are different issues.
