I have an Exchange 2003 Server running on SBS 2003. All of a sudden I cannot receive email from external recepients. Internal email works fine both incoming and outgoing and sending email to external recipeints works as well. When I try to telnet to the public IP of the server from a computer on a completely different network and Internet connection I receive a connection failed error. When I telnet to the Internal IP address of the SBS Server from a computer connected to the same network I receive a response.
