Have just installed Exchange 2007 SP1 on Windows Server 2008 SP2. Have used defalut configuration. Have enabled Anonymous access on Default Hub Transport and created a Send connector for my ISP. I am now testing telet from my internal network (have also tested external after forwarding port 25) but cannot connect. Have turned off firewall, but same problem. No problem to ping the address on the Exhchange server.
What am I missing?
