Alright here is the setup. Windows 2003 Server Standard SP2, Exchange 2003 SP2. Server is hosted at a dedicated server host provider. Its a single server set up so it is the DC and the Exchange Server. Got everything all set up, OWA works, and I can get Outlook working with it using pop3 setup as long as I dont have it authenticate for SMTP. if I check the little box where it says server requires authentication, use same settings as POP3 it just keeps asking me for my user name and pass over and over and wont actually accept them. However if I set it to do SMTP with annonymous settings it works just fine. This is a problem as i dont want my server to be able to do open relay. Unfortunately I can't lock it down till I can figure out why I cant authenticate. What steps do I need to do in exchange to make this work. Bonus points if you can walk me through getting it set up to use SSL but thats not a must.
