I have an existing Domain, example.co.za {This is windows Server 2003 standard}, I just recently installed a SBS 2003 R2 Standard in our Cape Town branch. {cpt.example.co.za}. Now replication is not allowed with SBS. example.co.za is my main exchange server and it uses an internet SMTP connection to our ISP. I set the SMTP connector in cpt.example.co.za to point to the example.co.za' ip. There is a Firewall to Firewall IPSEC VPN tunnel that connects the two sites. I have also created the DNS zones in example.co.za and MX record. This works fine for CPT to send mail out to the world and recieve mail back from the world, also Ican send internal mail from example.co.za to cpt.exaple.co.za,but the problem I have now is that I cannot send mail from cpt.example.co.za to example.co.za. Anyboday have a solution for this, it would be appreciated.

So, the environment is: Domain: example.co.za Main exchange servers FQDN: ?? SBS servers FQDN: cpt.example.co.za Internal mail flow from main exchange server -> cpt.example.co.za is OK Internal mail flow from cpt.example.co.za -> main exchange server is failed Check info: 1. Please describe the exchange version of main exchange server, its not a SBS server, right? 2. Is there any error event in the application log on the exchange servers? 3. Is there any NDR for undeliverable messages? Please post the content at here for analyzing 4. Please use queue viewer for troubleshooting the mail flow 5. On the SBS server, please use telnet to send a test mail to the mailbox on the main exchange server directly, see if the mail flow still blocks Resources: How to install Small Business Server 2003 in an existing Active Directory domain Exchange Server 2003 Mailflow

Could you provide the description part of the error events like the examples below? ==================== Event Type: Information Event Source: MSExchangeTransport Event Category: RemoteDelivery Event ID: 8003 Date: 9/17/2008 Time: 11:23:13 AM User: N/A Computer: EXCH03 Description: Resubmitted 1 message(s) from queue 'SmtpRelayWithinAdSite':'MySendConnector':'db2df65b-ff29-41a6-b36a-f52fbad0af47' because the queue has been inactive for longer than 12:00:00. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. ==================== So, we can only telnet main server via IP. Whats the error if we use the FQDN of the main server to telnet? Please check the DNS setting in the NIC, ensure the DNS server that SBS server used has the record of main server. And also check the Hosts file of SBS server, see if theres any entry that contains the wrong info

You have installed exchange 2003 on the main server, right? Hows the DNS setting? I noticed that the first error event is event 1194, right? Please check this article Please check the info in the AD Sites and services snap-in, see if theres any old DC object under the Default-First-Site-Name Please create a new test mailbox on SBS server, and then send a text message to main server, see if the symptom still persists Also run Netdiag and DCdiag to check the issue Resources: KB 828051 for event 8026 KB 322837 for event 2102 and event 8250 Accepting or denying a meeting request causes a "5.1.1" non-delivery report in Exchange Server MSExchangeAL events 8026 and 8260: Cannot access Address List configuration information
