how to proporly setup exchange server with domain name registrar and mx tables
I am planning on building a windows 2003 standard edition server and will load windows 2003 exchange server standard edition. My domain name is registered and my ISP modem has a static ip. So my first question is when i build windows and i setup active directory it asks you the fully qualified domain name of the domain to be, so do i put in the name of the dome that i registered or can i put say domainname.local. I don't plan on hosting the website from server just email. Second Question. Once i setup windows and i install exchange do i have to enter in any tables on the server to accept mail from the domain name registrar. So for example if someone from the outside world sends an email to say firstname.lastname@example.org it will go to my registered domain name hit the mx tables the shoot over to my server. Third Question for the mx tables on the domain name registrar do i just put in the ip of my modem and the name of my exchage server.
Forth Question. Should exchange be put on a separate server like a bdc or can you run it off the pdc. Lastly should i open ports 25 and 110 on my router or are they open by default
