I'm trying to configure SMTP, POP3, and IMAP4 for outside users so they can use their regular outlook outside the building rather then the web-based outlook application.

Most of the Exchange server is still in the default state, so I'm guessing all these services are up and running they just need to be properly assigned internal and external IPs and properly NAT and route stuff in the Cisco PIX firewall to get everything working properly and pointing where it is supposed to go.

When right clicking on the Virtual Servers, one sees "Assigning a Static IP Address" should this be an internal or external IP address? I'm assuming this should be the internal IP address of the Exchange server and the in the PIX we should route "smtp.domain.com", "pop3.domain.com", and "imap4.domain.com" with the associated ports to the internal IP address and port? Is that correct?

On Exchange Server 2003 POP and IMAP are not running by default. You will have to start them. SMTP runs by default. You will have to forward the appropriate ports to your Exchange Server internal IP address. Make sure your ISP is not blocking your server ports (go to grc.com and use ShieldsUp to test them). You should be able to telnet to your ports from outside your LAN once everything is working. I do not see the "assigning a Static IP Address" on my server but I think you are correct about that being your internal IP. Without knowing exactly where this item is I can only guess.
