On a recently installed Excahnge 2010 server I am not able to connect to the SMTP port. When it was originally installd I was able to telent into port 25 and get the mail server header info but now I am not and I am not getting any incoming mail.
The server does not have any anti-virus software or spam filtering software and the receive connector is set to allow anonymous connections. All available updates are installed and SP1 has been installed. All after the problem started. I know it is not a firewall issue because I am not able to connect from the local network or even the local machine.
The system was not a upgrade, it was a clean install and it is running Server 2008 R2 with Exchange 2010 SP1. The system is running the Hub Transport, Client Access and Mailbox roles as well as DNS and AD. It is the only server in the network. Any help would be appreciated.
