Change 220 response with the FQDN of the Exchange 2003 Server

I have an Exchange 2003 server that is now under new ownership.  The former domain name is coming up when I telnet into port 25 and get the SMTP response.

Is there a way to change this to the new domain name without reinstalling the server?

Please not I'm not asking how to receive mail for a second domain - that is already configured and working via recipient policy.

Here is an example:

220 Microsoft ESMTP MAIL Service, Version: 6.0.3790.39
59 ready at  Tue, 6 Apr 2010 16:05:00 -0800

I need the smtp response be equal the ""...

I found on technet an event sink thanks.  It's a small operation and if there a be it.

Thank you for your time and consideration,
