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.
