Exchange Server as POP3

I've set up Exchange 2003 Enterprise on a test server running Win 2003 Enterprise Server. It is not a DC, but is a member of a domain. I can send and receive internal (user@domain.local) emails, can send external emails (user@internetdomain.com), but cannot receive external emails. We've added the appropriate mx record for a fqdn test site pointing to the exchange server which can be reached throught a router/firewall by a static IP/NAT forward. The DC is also provides DNS configured with appropriate DNS forwarding. My questions are

1. Do you have to install the out-of-the-box POP3 service in Windows Server 2003 even though Exchange is installed

2. Do any white papers exist on this particular aspect of configuration

Thanks.

Hi - not sure what this has to do with POP. Do you need POP for some
reason?
See if http://www.msexchange.org/tutorials/MF002.html helps - it's written
for E2k but should help. You need to set up your recipient policy to handle
internetdomain.com - and then I suggest you change the default/reply domain
to internetdomain.com so that it's everyone's default address.

One, no you don't need the POP3 service from W2K3.

Do you have both address listed on your recipient policy?
ESM- Recipients - Recipient Policies
Do the e-mail addresses both have 'This Organization is responsible for all
mail delivery to this address' checked?

If the above are correct:
Can you telnet to the server from outside?
syntax: telnet IP 25

If so, on the 'rcpt to:' line use only the first part of the email address
before the @ sign.
It will the append the domain to it, is this domain correct?

Thanks to both of you for the timely response and help. Turns out I had not allowed port 25 through the firewall. Once that was done, all was well.
