If you want to use SMTP to allow mail to be delivered directly to your
Exchange from the internet (recommended), you need a 'fixed address' so that
mail destined for your domain knows where you are.

Is you public IP fixed, or dynamic?

If it's dynamic, then you should call your ISP and enquire about a fixed IP,
and find out whether they permit things like mail servers. Some ISPs will
block certain things, unless you purchase a 'business' account. If you can't
get a static IP, you could check out the dynamic dns services of
organizations such as dyndns.

One way or another, you must have an MX record that will enable your
exchange server to be found on the internet for mail delivery.

Note that you don't have to use SMTP, you can still set up exchange and use
the pop3 connector. In this case, email is still delivered to your ISP, but
the exchange server - rather than each client - picks up the mail from the
pop accounts and places it in the users exchange mailbox. This isn't the
best way, but that functionality is there if SMTP cannot work for you.
