I am migrating from Ex2003. In Ex2003 I remember changing the FQDN that was presented when I would telnet to port 25 on the local box. I created a reverse pointer record in DNS that matched the name present in my banner header.
In other words I would telnet to port 25 and it would come back mail.myserver.com. Then I created a reverse PTR record in DNS to point mail.myserver.com back to the IP of my mail server. This was needed because certain mail servers would not accept mail until I did it.
I am having problems doing this in Exchange 2010. I go to Server Config->Hub Transport-> Receive Connectors. I am not able to put in my FQDN into the Default Connector. The only name it will accept is my local AD domain name (ie exchange2010.myserver.lcl). Since this is not a FQDN, how do I enter one in to keep the other mail servers on the net happy?
Hope I was clear on this.
