I am in the process of setting up Exchange 2010 in my Exchange 2003 system. i currently have my CAS array setup with hub transport installed. I have successfully setup my edge transport in my dmz and have setup the subscription and verified connectivity by using the command test-edgeSynchronization and it comes out successful. What i would like to try is to test this setup via telnet to edge server and send an email. I would like to know if it is possible to send an email this way to one of the email boxes that still resides on my exchange 2003 server. Thanks.
