UPDATE: So I fixed my user profile issues after having to re-install and reconfigure Windows 2003 on my server. I have since installed FTP, HTTP, SMTP and POP3 roles onto it. My FTP configuration works just fine, as does my HTTP setup. I have not been able to get the SMTP and POP3 working properly, however. Well, let me rephrase that... they may be working just fine, but I may not be able to tell due to the fact that my server is using a local domain name and is only accessible over the internet via an IP address. So my question is this: can emails be sent/received over an IP address without having a proper domain name, or must I register a domain in order to do so? I have been trying to test this myself, but despite having sent emails from both my AOL address and my server address (to each other) I have not yet received any of them, nor have I received any "error - can't send" emails. Any ideas as to why this is or how to fix it?
