I have an Exchange 2010 server running Exchange 2010 SP1
If I run telnet myservername.com 25
I get a response, but it's my local domain name (myservername.lcl). Other mail servers are seeing this local domain name as well and are not receiving mail because they can't resolve the local domain name.
If this were Exchange 2003 I could change the domain name seen by other servers in the SMTP virtual server. How do I change the domain name seen by other servers in Exchange 2010?
It's not possible to change the FQDM in the default connector -- it's not allowed, the name must be the local domain name.
I am (was) able to change the banner using the Set-ReceiveConnector comandlet. However, when a HELO command is issued, the same local domain name is being broadcast.
There must be a way to change this so other mail servers will not reject mail.
How can I do that?
