Newbie to SBS 2003, Mail Receiving Problems

[Archetypture]

First off, I'd like to apologize if this has been answered before, or if it's so incredibly stupid that it's amazing that I can't figure it out myself.

I'm the "IT guy" for our small architecture firm, which means I'm an architect with a dangerous small bit of knowledge about computers and networks. We recently installed SBS 2003 on our file server, and I'm trying to get Exchange 2003 set up correctly.

Background: We used to use Outlook and an external POP3 mail server to route out mail. I called our email host and had them reroute all mail to the firewalled static IP address of our router.

In the DNS area of the TCP/IP connection, I added the IP address of our router as the primary address. This allowed me to send emails out to external address, but I cannot currently receive emails. I'm stumped as to what I'm doing wrong. Any help would be appreciated. Please remember to use small/common words in any help suggested. Thanks in advance.

who handled changing the MX records in DNS for you and are you sure they did that right

It was one of the tech reps for our ISP, and I guess I can't say whether he did it right, but since we can send mail correctly, I might assume that he did the incoming correctly as well. I'll call them to double-check, though.

Thanks for the reply.

Well......

sicktrick, you were correct. They fubar'ed something on their end. He tells me they changed whatever needed to be changed (CSF maybe?), and that we should be up and running in a few hours.

Thanks for the suggestion!

if ever you face this situation again,

at the command prompt, preferably from a 3rd party machine like your PC at home w/ a cable modem, run the command:

nslookup

then at the nslookup prompt type:

set type=mx

then just type in domain name

architect.com

that will show you the IP addresses that are set to receive mail for architect.com
