Exchange 2010 FQDN

I'm trying to set up the FQDN on an SBS 2011 server that runs Exchange 2010.  If I telent to the server on 25, it responds with mail.domain.local, but I need it to respond as mail.domain.com.  I set up a new Receive Connector that uses the FQDN mail.domain.com b/c the default connector uses mail.domain.local.  Then I restarted the MS Exchange Transport service, but the mail.domain.local still shows.  The reason I'm doing this is that I need to set up a PTR for mail.domain.com to go to the public IP of the server and need the server to respond to mail.domain.com.

Any suggestions?  Sounds more like an Exchange issue but have to mention the OS anyway :)

The proper way to configure is using the "set up your internet address" wizard. The following is for SBS 2008 but the process is the same. In step #7 click advanced and replace remote with mail

I'm hesitant to do that b/c this is a live server that's being worked on remotely.  And if the Internet connection fails, it means me driving over an hour to the client's site.  There has to be some way to do it other than the wizard.

This is SBS, you MUST use the wizards. There is a FAR greater chance of failure if you don't. The wizard updates Exchange, internal DNS for the external domain name, IIS, certificate services, and more. You cannot do all of it manually.

When you run the wizard you will loose the connection while IIS resets, but you should be able to reconnect within 2 minutes. I always have a second method of access when making changes such as that.....just in case.
You could temporarily install something like free LogMeIn for safety.
