SBS 2011 Exchange Migration
Hi All we have tried moving the SMTP receive port across to the new exchange 2010 server. We have migrated from windows small business server 2003. When trying to telnet we dont get a response from outside the network. If we telnet to the server within the network from the old server to the new server it shows a response from the Microsoft ESMTP Mail Service.
Looks like the Internet Receive connector isn't responding, but the default SBS2011 one is.

Have you correctly forwarded port 25 on the router to the new Server?
Check if the internet Receive connector has to correct IP addresses set. It should accept mail from the router's IP address.
Select properties on the SBS Internet Receive connector. Select the Network tab. At the "Receive mail from remote servers...." part it should look something like this:
0.0.0.0-192.168.0.255
192.168.1.2-192.168.1.2
192.168.2.0-255.255.255.25
In this case 192.168.1.2 is the IP of the router.

In this case 192.168.1.2 is the IP of the router.
The default receive connector should be configured to accept mail from * by default - all source IPs.
But you also need to enable "anonymous" in permission groups for that receive connector. This does not make you an open relay, it just allows remote machines to connect to your SMTP server and send you mail without being authenticated.

Thanks I have done all of those checks and it is all set up correctly. A response is recieved from port 25 (as in the screen goes blank) but no HELO string appears after the screen clears.
Have you ran the Fix My Network wizard?
Double check the Internet Receive Connectors Network tab to make sure that its configured to receive mail from your routers IP.
What router are you using?
