I'm setting up Exchange Server 2003 in my office for no other purpose than to teach myself Exchange. I have my own registered domain name but I do NOT have a static IP address from my ISP. I've seen the SMTP settings in Exchange but nothing about POP3. Is this because I can't receive external e-mails on my exchange server without a static WAN IP address? If so then assume I get a static IP address... What is the next step to do? Something about pointing my domain name to certain DNS servers??? IÃƒÂ¢Ã‚Â€Ã‚Â™m hoping I don't have to get a static IP address and that there is a setting in Exchange.
