Exchange server not receiving Internet mail;

Client has just installed an Exchange Server 2003 SP2 running on Server2003 Ent. We can send mail locally and over the Internet but cannot receive Internet mail. When the Internet mail recipient replys, no NDR or error saying the message was not delivered; appears the message went through but is never received.

-On the web host, I created an A record "server.domain.com" pointing to the Exchange IP and an MX record pointing to "server.domain.com".

-Opened port 25 on the local firewall.

-Created a local MX record for server.domain.com.

HAve a check between the SMTP gateway and your exchange server. The mails might be received and still residing on the SMTP gateway....waiting to be delivered to the exchange server.

Below are links showking how to test the SMTP manually.

The administrator account didn't have a mailbox setup. I just created one and checked; obviously nothing there. Try again?

Moron6969Author Commented:
I checked the mailbox info from the exchange mgt console and it appears there are messages items listed in the inbox that do not appear in the client inbox.
So it looks like mail is received by exchange but not delivered to the client workstations.

Any ideas?

good
on HUB transport server, open receive connector properties and change logging level to verbose

then go to http://mxtoolbox.com/ and type your domain name and perform SMTP Test

then go to C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive

open today's receive connector and examine it
